5 FAQs of High Thermal Mullite Corundum Crucible

What is the maximum temperature a High Thermal Mullite Corundum Crucible can withstand?
High Thermal Mullite Corundum Crucibles are engineered to endure extreme temperatures up to 1700°C (3092°F) continuously, with short-term peak resistance up to 1750°C (3182°F). This makes them ideal for high-heat applications like metal melting, ceramic sintering, and advanced material research.

Which materials are suitable for melting in these crucibles?
These crucibles are compatible with non-ferrous metals (e.g., aluminum, copper alloys), precious metals, glass, and ceramics. Avoid highly corrosive substances like strong alkalis, acidic fluxes, or reactive molten salts, as they may degrade the crucible’s structure over time.

How does the durability compare to graphite or clay-graphite crucibles?
Mullite corundum crucibles outperform graphite in oxidation resistance and thermal shock stability. They resist cracking during rapid temperature changes and have a longer lifespan in high-oxygen environments where graphite would oxidize and deteriorate.

What maintenance practices extend the crucible’s lifespan?
Preheat the crucible gradually to avoid thermal stress. Clean residues after each use with gentle tools (avoid abrasive scraping). Store in a dry environment to prevent moisture absorption, which could cause cracking during heating. Inspect regularly for microcracks and replace if structural integrity is compromised.

Why choose mullite corundum over other refractory crucibles?
This material combines mullite’s low thermal expansion with corundum’s high hardness and chemical inertness, offering superior thermal stability, reduced contamination risk, and resistance to slag erosion. It’s more cost-effective than pure corundum crucibles and excels in applications requiring repeated thermal cycling without performance loss.
