5 FAQs of High Hardness Aluminium Oxide Al2o3 Refractory Ceramic Crucible with Volume 500 ml

What’s the highest temperature this crucible handles?
It withstands constant 1750°C easily. Short bursts near 1800°C are okay sometimes. Don’t run it hotter than that. The material loses strength fast above 1800°C. It might crack or fail. Stick to 1750°C max for safety.

Can it handle sudden temperature changes?
It handles moderate thermal shock well. Don’t take it straight from extreme heat to cold water. That stresses it too much. Let it cool down slowly first. Controlled heating and cooling cycles are fine. Avoid big, fast temperature swings.

What chemicals won’t damage it?
Alumina resists most acids and bases very well. It handles molten salts, common metals, and glasses fine. Avoid strong alkalis like hot sodium hydroxide. Avoid hydrofluoric acid. These chemicals attack the alumina surface. Check chemical compatibility first.

How do I clean it after use?
Remove leftover material once it cools. Use mechanical methods mostly. Scrape it gently. Use a wire brush if needed. Avoid harsh chemicals unless necessary. Sometimes soaking in dilute acid helps. Rinse it thoroughly with water after cleaning. Make sure it’s completely dry before reheating.

How long does it last before needing replacement?
Lifespan depends heavily on use. Extreme temperatures, thermal shock, and harsh chemicals wear it down faster. Look for cracks, deep pits, or significant surface erosion. Thinning walls mean it’s weakening. Replace it when damage appears. Regular inspection is important.
