Graphite Block

We can supply various sizes of graphite blocks with high strength(50~100Mpa) high purity(99.99%)and high density(1.8~1.90g/cm3). It has the properties of fina grains, uniform structure, and it is typically used as the construction materials of nuclear reactor, the heater of vacuum furnace and high-frequency furnace, the crucible and mould ofr melting metals, the internal lining of reduction furnace, mechanical sealing ring in the erosive medium and industry ambiance.

Q:What about the thermal conductivity of graphite rods?
Its thermal conductivity is not only more than steel, iron, lead and other metal materials, and with the rise in temperature, thermal conductivity decreases, which is different from the general metal materials, at very high temperatures, graphite and even tend to adiabatic state.
Q:Not that the solid does not conduct electricity, like the solid potassium chloride, but why the graphite rods, wires, these solids can conduct electricity
Since there is no moving charge in potassium chloride crystals, it naturally cannot conduct electricity. Potassium chloride in molten water and in molten state, because of the free movement of chloride and potassium ions, it can conduct electricity
Q:How good is the conductivity of graphite and the conductivity of copper?
It's copper. Copper resistivity is 10 negative, 8 times only after silver, and graphite resistivity magnitude is negative 6 timesGraphite rods are used in dry cells because they are stable in electrolytes, free of corrosion and low in industrial cost
Q:How many times will a high pure graphite stick turn red at temperature?
With the increase of temperature, the oxidation rate is increased, if the nitrogen protection, can reduce the oxidation rate, so some high temperature furnace, vacuum furnace and vacuum extraction is to prevent the oxygen in the air oxidation of graphite, McNair to answer your questions.
Q:Bought a high pure graphite stick, how so hard?! Doesn't it say that graphite is soft? Why is it so hard?
High pure graphite rod belongs to artificial graphite is processed by tar pitch coke and the like, through the press, after N N in the baking leaching intensity, hardness increased, high purity graphite, graphite electrode made of graphite mould etc..
Q:What is Teflon graphite stick for?
Graphite can improve the wear resistance, thermal conductivity, self lubrication, electrical conductivity, heat resistance and deformation of polytetrafluoroethylene. With the application of high temperature resistance, wear resistance, corrosion resistance and other environments, in addition to food, insulation, oxidant environment, graphite modified (enhanced filled PTFE) can PTFE can be used instead of the original environment.
Q:What is the difference between the conductive effects of different grades of graphite? Refers to the pencil core
Such as "H" or "hard" English (hard) on behalf of the prefix, clay, pencil hardness to said. The bigger the number in front of the H (such as 6h), the harder the pencil core, the greater the proportion of clay in the cartridge to the graphite, the less pronounced the word, and is often used to duplicate.
Q:Copper, graphite rods, dilute sulfuric acid, why not make up the original battery?
Because there is no oxidant, and can not react with dilute sulfuric acid, and if the graphite rod in the vicinity of the continuous access to oxygen, you can form the original battery
Q:What kind of sketch do you want, Shi Mobang?
Instead, it is the lead, and use the pencil almost, but it is not like a pencil with a wooden package, is a core bare, so it is easy to break, the price is not expensive... The beginner is recommended to use the pencil lead is difficult to master the appropriate
Q:Is graphite rod resistant to sulfur corrosion?
It is widely used in petroleum, chemical, hydrometallurgy, acid and alkali production, synthetic fiber, paper making and other industrial sectors. It can save a great deal of metal materials.
We strictly follow the modern testing standard, such as ISO3069 standard, DIN24960 JB/T41271. It is for this reason that we has built a strong reputation in the market for it quality products. We always insist on building strong and long term relationship with our customers.We are willing to make persistent efforts to seek common development and create the future with friends from all over the world!
