Product Description:

Specifications of Black Silicon Carbide:

Black silicon carbide grit F 24-240, sic 98.5%min, F.C 0.2%max, Fe2O3 0.3%max. Packing:25kg bags be packed into 1mt big bags. 

- Description:

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is sharp and has electrical and heat conductivity in some degree.

- Application:

    ♦As the abrasive: used for abrasive, such as grinding wheels, whetstone, grinding
     wheel, sand tiles etc.

    ♦As the metallurgical deoxidizer and high temperature material.

     Four main application areas of SiC: functional ceramics, advanced refractory,
     abrasives and metallurgical materials.

   ♦High purity single crystal, used to manufacture semiconductors, manufacture of
     silicon carbide fibers.

   ♦Silicon carbide is very hard, with excellent thermal conductivity, as a semiconductor
     and high temperature resistant to oxidation.

- Specification:

Grits: F12-90, F100-240.

Q:What can light hydrocarbon carbon five be packed with?
Light hydrocarbon carbon fiveLight hydrocarbon carbon five is a light yellow or colorless transparent flammable liquid with a density of 0.60-0.68 and a boiling point of 36.1 degrees. The calorific value of liquid light hydrocarbons is 10800kcal/kg. (the current price in Chengdu is 2000 yuan / ton, and the monthly supply is about 1000 tons.).
Q:What is the carbon emission of the air conditioner?
Summer, less air-conditioning, 1 hours to reduce carbon emissions of 0.621kg, the action of the low carbon family is not how much money you need to pay, but to change some of your habits and habits, and contribute to environmental protection. Hand in hand to join hands to tackle climate warming, perhaps our hearts will be less worried about the future......
Q:What should we do to reduce carbon emissions in our lives?
The use of public transport, of course, is best to walk long distances, as far as possible the use of roads or railways, aircraft carbon emissions, the largest use of disinfection chopsticks, do not use disposable tableware, handkerchiefs do not use napkins
Q:Carbon fiber refractory?
Carbon fiber carbonization points: 1, graphitized carbon fiber cloth, can withstand 2000--3000 degrees of high temperature;
Q:What is the basic principle of carbon fourteen detection?
Carbon fourteenCarbon fourteen, a radioactive isotope of carbon, was first discovered in 1940. It is produced by hitting twelve carbon atoms in the air through cosmic rays. Its half-life is about 5730 years, the decay is beta decay, and the carbon 14 atoms are converted to nitrogen atoms. Since its half-life is 5730 years, and carbon is one of the elements of organic matter, we can infer its age by the 14 component of the residual carbon in the dying organism. When living in the biological, because need to breathe, the carbon content of 14 in its body is about the same, the organisms die will stop breathing, at this time the carbon 14 in the body began to decrease. Since the proportion of carbon isotopes in nature is always stable, one can estimate the approximate age of an object by measuring its carbon 14 content. This method is called carbon dating. Other commonly used methods include potassium argon measurements, potassium argon measurements, thermoluminescence measurements, and others;
Q:Is badminton all good as carbon or aluminum carbon? Does carbon fiber on the Internet mean total carbon?
The badminton racket is different in texture. Mainly divided into titanium, carbon, aluminum, carbon fiber, aluminum alloy and pure iron, pure aluminum. Among them, the best material is titanium, followed by carbon, aluminum, carbon fiber, aluminum alloy and pure iron, pure aluminum. Related knowledge: before 70s, the material is almost entirely of wood and steel in the world, in 70s began to use Aluminum Alloy, now the world is completely new materials such as carbon fiber, titanium alloy, high strength carbon fiber and other materials because they are lighter, stronger, more durable and can absorb more vibration and shock, at the same time let the racket maker the hardness of the racket, ball, have more space to play ball on the performance design. When choosing the racket, best to look at this is what a racket made of material, usually in the racket racket rod and a racket frame will be labeled with the material, sometimes is the same as YONEX ISO-800TOUR High Modulus Graphite shot rod (high strength carbon fiber) frame also has the same mark, and some racket racket rod and frame material is not the same as: YONEX ISO-250LONG High Moudulus Graphite shot frame for Graphite (carbon fiber). Some also took pole, beat box made of the same material the labeled All Graphite or All Graphite racket only in a local frame or shaft. Sign formal products are accurate and reliable, and fake products marked is printed, it is generally used in relatively poor carbon cloth, compared the density, purity and regular products so large that the cost is very low.
Q:What are the brands of carbon batteries?
Carbon batteries are not recommended, and each carbon cell can permanently destroy one cubic meter of soil or more than a dozen cubic meters of water!Today's alkaline batteries are basically mercury free environmentally friendly batteries, which can be thrown away with common waste, with very little environmental damage!What's more, the durability of alkaline batteries is several times that of carbon! Now alkaline battery quality is good, basically will not leak alkaline material!If you think the alkaline battery is not good, it is recommended to use Ni MH rechargeable batteries. The battery is also environmentally friendly and can be recycled for long periods of time,Initial input slightly larger, but if the correct use and charging, cost-effective! Especially for toys with large power consumption!The disadvantage of Ni MH batteries is memory, which needs to be used up and recharged, and is easy to discharge. It loses ten percent of the battery power every monthA few! But now there is a new type of Ni MH rechargeable battery, which is introduced by the manufacturer as if it has a semi discharge of less than fifteen percent and a low memoryOf! More suitable for clocks and watches, remote control, these electrical appliances! What's more, the voltage of Ni MH battery is usually 1.2V, which is lower than that of ordinary dry electricityPond. It is recommended to study the charging, storage and usage of NiMH rechargeable batteries. The correct method of use can save moreMoney, more environmentally friendly!The earth is my home, and it depends on everyone!!
Q:What is the starting temperature and final forging temperature of carbon steel?
2. final forging temperatureThe final forging temperature, that is, the temperature at which the billet terminates, the final forging temperature shall ensure that the billet remains sufficiently plastic until the end of the forging, and that the forging is recrystallized after forging3. forging temperature rangeForging temperature range refers to a temperature interval between the initial forging temperature and forging temperature. To determine the basic principles of forging temperature, can ensure that the metal has a high plasticity and low deformation resistance in the forging temperature range, and organization and performance requirements. The forging temperature range should be as wide as possible, to reduce forging times, improve productivity.The starting temperature and the final forging temperature and the temperature range of the forging can be determined by the Fe Fe3C alloy phase diagram. The present state of the iron carbon alloy is a part of the iron carbon alloy with carbon content ranging from 0 to 6.69% (i.e., Fe - Fe3C part)The forging temperature range of carbon steel is shown in the shadow line shown in this figure
Q:Consult the carbon content of austenite
Pure iron carbon alloys, austenitic (A) carbon content in different grades, different temperature and different, in more than 727 degrees (727 degrees when the carbon content is 0.77%), 1148 degrees, 2.11% carbon content with see iron carbon phase diagram
Q:Carbon steel with carbon steel, carbon steel yuan yuan is the same? The trouble to know the answer urgently
Not the same! Simply say: the high quality carbon steel or carbon steel. Specifically speaking is the carbon content of less than 0.08%. and carbon steel compared to its quality is excellent, there are strict requirements to ensure the chemical composition and mechanical properties, phosphorus and sulfur are high quality carbon steel eliminating lower impurity content.
