Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke. Its hardness is between that of fused alumina and synthetic diamond and mechancial intensity of it is also greater than that of fused alumina. It is brittle and very sharp and  has a certain degree of electrical and heat conductivity

Q:What is the the best ratio of mortar in refractory cement?
Specifical proportions are as following: 42.5R cement is 425 rapid hardening cement. Using the 425 cement to compound the mortar. The reducion of cement will naturally impact the workability of the mortar. The mix design standard of the mortar specifies the minimum amount of cement is not less than 200kg / m3. If it is composite mortar, and the strength and workability can be ensured, it is Ok to use 425 to compound. You can look for instructions of mixing proportion of mortar online as a reference.
Q:Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
Q:What is glass furnace used high-grade refractory materials?
Glass furnace need to use refractory that temperature resistance is more than 1600 degrees, corundum mullite brick, etc., What's more, in the key parts of the glass furnace needs to use chromium zirconium corundum material, such as alumina hollow brick and corundum brick.
Q:What are the disadvantages of the refractory industry?
The rapid development of continuous casting technology allows Hua Heng refractories to be improved in variety and quality. The development of refractory for continuous casting has a significant impact on the production of continuous casting and quality of continuous casting billet. Constructing and putting Baosteel into action has greatly pushed the improvement of the refractory technology. Continuous casting refractory is an important part of the continuous casting machine. In addition to the general characteristics of refractories, it is also required functions that can purify molten steel, improve the quality of steel, stabilize temperature and composition of the molten steel, control and regulate the molten steel flow. Therefore, it is known as functional refractories. Continuous casting Refractories include: (1) ladle refractory - ladle lining, permanent lining and ventilation components; (2) tundish refractories - permanent lining, coating, insulating plates, clad etc; (3 ) functional refractories - long nozzle for non-oxidizing casting, submerged nozzle, monolithic stopper, sliding gate; (4) ceramic purifier for purifying molten , slag dam, alkaline paint and horizontal separating ring and gate board for continuous casting.
Q:How long is the duration of fire resistance of autoclaved flyash-lime bricks?
How long is the duration of fire resistance of autoclaved flyash-lime bricks?
Q:What is the difference between wear-resistant material and refractory material?
Focus is different. Some materials are called wear-resistant and refractory material. For example, refractory castable with high strength and wear-resistance, impressionable plastic material or brick. They all begin with fire-resistance and wear-resistance.
Q:Does anyone know the difference between refractory and thermal insulation material?
Refractory refers to inorganic nonmetallic material, whose refractorinessis not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulation material also belongs to refractory as long as its refractoriness is higher than 1580℃.
Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
Go eastward 200 meters from the south gate of cultural square.
Q:What refractories can withstand high temperature above 2100 degrees?
Usually a dryer will not have such a high temperature. I do not know what you would use it for. Refractory cement coupled with quartz sand can work for 4 to 5 hours. So you can try cement coupled with corundum or superfine bauxite for better effect.
Q:How is the development of Xinmi refractories industry? What's its advantages and disadvantages?
The disadvantage is too small yard, vicious competition among each other and confusion in the market, which should be the inferiority of national refractory industry . Xinmi Refractory is well developed in recent years, mostly acidic and neutral refractories. It is still relatively rare to use in iron parts, steel pile with a satin and other basic refractory slide .
