Upper Graphite Heat Shield

Upper Graphite Heat Shield 

Upper graphite heat sheild can protect the device from damage and contamination in graphite hot zone.It requires advanced processing tecnologies and high quality graphite materials.The high mechanical stregth graphite can avoid cracking during 

the calcination.

Adcantages:

1.Graphite heat sheild have high thermal stability.

2.Graphite heat sheild have good electric conductivity.As temperature rises, electrical conductivity increases. 

3.Graphite heat sheild have high thermal conductivity.The thermal conductivity of graphite is higher than that of many metals and falls with increasing of temperature. 

4.Graphite heat sheild can resist thermal shock. so rapid heating or cooling is not a problem.

5.Graphite heat sheild can resist corrosion.It can be widely used in acid based environments.

6.Graphite heat sheild are not wetted by molten glass or by most molten metals.

7.The tensile,compressive and flexural strength of graphite heat sheild are very high.

8.Graphite heat sheild have high purity.
