Function:

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