Product information

These products are made of common chemical porcelain as raw materials, and are formed by the process of grouting or hollow grouting method. They are suitable for the analysis of carbon and sulfur content in steel and iron samples. Porcelain ark is suitable for the test of volatiles from light mineral samples. Such as charcoal, can be used to replace the volatile crucible.

Product Details

High Temperature Resistance

It has the characteristics of high melting and boiling point and can be used at high temperature without being affected.

Electrical Insulating

Insulator has high resistivity at room temperature. It can be used in equipment requiring insulation.
