GENERAL SPECIFICATION of LARK ALUMINA CRUCIBLE
- Alumina products are fragile. Please handle them carefully and avoid collision during unpacking, transportation, handling, and cleaning. Check whether any micro-cracks exist before using alumina products. Products with micro-cracks should not be used.
- LARK ALUMINA CRUCIBLE products should be completely dry before using them. If they get wet, let the crucible or tube dry naturally before using them. If dry crucibles by placing in a dryer or oven, make sure that the dry process goes slowly.
- Do not load too many materials in alumina crucibles, which can increase the possibility of uneven heating. Alumina crucibles are sensitive to thermal shock. Try to warm up the furnace chamber slowly.
- A heating rate of 150°C/hour is recommended for the first 1-1.5 hours so that the crucibles can be evenly heated to reduce the impact of thermal shock.
Why choose alumina products?
High purity alumina products can withstand very high temperature under reducing, inert or high vacuum condition. They remain good chemical resistance under high temperatures, and have excellent wear and abrasion resistance.
What’s the highest temperature that 99.9% alumina products can withstand?
Alumina products can withstand up to 1750°C (3182°F).
