Silicon Carbide Crucible

High-grade silicon carbide crucible for firing lithium battery anode material and for the powder metallurgy industry, made from silicon carbide raw material of 98 % content.

Grades / types: Single specification

Product overview

Silicon carbide crucible is a high-grade refractory product for firing lithium battery anode material and for the powder metallurgy industry, including the sponge iron large tunnel kiln.

The source states that the crucibles are made from high-grade silicon carbide raw material with a content of 98 %, and that a special process is applied when the raw material is selected so that its purity stays high.

They are used in the field of new inorganic materials, principally lithium battery negative-electrode material and powder metallurgy.

Key characteristics

Made from high-grade silicon carbide raw material of 98 % content
A special process is applied in raw-material selection to keep raw-material purity high
