Corundum Mullite Crucible

Corundum Mullite Crucibles are made by combining corundum and mullite materials into one crucible for enhanced thermal shock resistance, high temperature stability and chemical corrosion protection. Corundum is an aluminum oxide crystal while mullite is an aluminum silicate mineral; when combined together they create an unrivalled combination for chemical corrosion protection.

Corundum mullite crucibles are widely utilized for high-temperature applications, including melting and casting metals, alloys, and other materials. Their exceptional durability and resistance to extreme temperatures make them suitable for use across industries including metallurgy, foundries, and laboratories.

These crucibles come in various sizes and shapes to meet various melting or casting requirements. They’re often utilized when other forms of crucibles may not be up to the challenge, such as applications that involve extreme conditions.
