Graphite crucible has good thermal conductivity and high temperature resistance. Thermal expansion coefficient is small. It has a certain strain resistance to acid and alkaline solution of strong corrosion resistance and excellent chemical stability. It is widely used in metallurgy, casting, mechanical, chemical and other industries.

In recent years, adopted high temperature resistant composite material, such as: silicon carbide, alumina, silicon carbide, ferrosilicon do skeleton of the crucible, clinker, etc. 

The clinker to improve crucible product quality,enhance the crucible density and mechanical strength has a significant effect.

Packing & Delivery time:

Usually use plywood case or cartons, with enough fillings to protect the products avoiding damage

Usually takes 10--25 days after confirmed, which is decided by the quantity.
