5 FAQs of 95% 99.7% Al2o3 Alumina Alsint C799 Cylindrical Ceramic Crucibles Sagger Boat With Lids

What are the max temperatures for these crucibles?
The 95% alumina handles 1700°C max. The 99.7% pure alumina handles 1800°C max. Do not exceed these limits. High purity means higher heat resistance.

What chemicals can these crucibles resist?
They resist most acids, alkalis, and molten salts well. The 99.7% pure version offers better chemical resistance. It’s less likely to react with aggressive materials. Avoid strong hydrofluoric acid and hot phosphoric acid.

Will these crucibles crack from sudden temperature changes?
They handle moderate thermal shock. The 95% alumina version typically handles sudden changes better than the 99.7% version. Always preheat them gradually. Avoid extreme, rapid temperature swings to prevent cracking.

Why is the surface so smooth?
The fine, dense surface minimizes material sticking. It helps keep your melts pure. It also makes cleaning easier between uses. This smooth finish is a key feature of quality alumina ceramic.

What are the main uses for these crucibles?
They work best for melting, calcining, and sintering materials. Common uses include precious metal refining, ceramic powder processing, and lab analysis. They are stable containers for high-heat work. The lids help contain samples and reduce contamination.
