High Quality Multiple Baking Graphite Block/Carbon Graphite Block for Electrical Furnaces

High Purity Graphite Block

1. High temperature resistant, graphite block is known as one of the most high temperature resistant materials. Its melting point is 3850 ℃ + 50 ℃, boiling point of 4250 ℃. It under 7000 ℃ high temperature arc 10 s, graphite loss minimum, meter graphite loss of 0.8% by weight. Thus, high temperature resistant performance of graphite is prominent.

2. Thermal shock resistance of special: graphite has good thermal shock resistance, namely when the sudden changes in temperature, small thermal expansion coefficient, thus has good thermal stability, when the change of temperature, thermal shock, won't produce crack.

3. Thermal conductivity and electrical conductivity: graphite has good thermal conductivity and electrical conductivity. It compared with the general material, its thermal conductivity is very high. 4 times higher than stainless steel, and 2 times higher than carbon steel, non-metallic 100 times higher than the average.

4. Lubricity, graphite lubricating performance similar to the molybdenum disulfide, the friction coefficient is less than 0.1. The lubrication performance varies with the scale size, the greater the scale, the smaller the coefficient of friction, the good lubricity.

5. Chemical stability: under normal temperature graphite has good chemical stability, can acidproof, alkali resistance, corrosion resistance to organic solvent.
