Function:
1.Graphite blocks have high thermal stability.Graphite does not melt but sublimes at about 3627 ℃ .
2.Graphite blocks have good electric conductivity.As temperature rises, electrical conductivity increases.
3.Graphite blocks have high thermal conductivity.The thermal conductivity of graphite is higher than that of many
metals and falls with increasing of temperature.
4.Graphite blocks can resist thermal shock. so rapid heating or cooling is not a problem.
5.Graphite blocks can resist corrosion.It can be widely used in acid based environments.
6.Graphite blocks are not wetted by molten glass or by most molten metals.
7.The tensile,compressive and flexural strength of graphite are very high.
8.Graphite blocks have good sliding properties.It can slide itself without lubricant.
9.Graphite blocks have high purity. Graphite can be purified to 20-30 ppm in block or less than 5 ppm for the
finished items.
