5 FAQs of Alumina Al2o3 Ceramic Crucible/boat Container Ceramic Products

Alumina Al2O3 ceramic crucible/boat containers are widely used in high-temperature applications. Here are 5 common questions about these products. What makes alumina ceramic suitable for high temperatures? Alumina ceramic has a high melting point above 2000°C. It resists thermal deformation even under prolonged heat exposure. This stability comes from its strong atomic bonds and dense structure. How high a temperature can these crucibles handle? Most alumina crucibles withstand temperatures up to 1800°C. Specific limits depend on purity levels and manufacturing methods. Higher alumina content (99%+) allows better performance in extreme conditions. Can these containers survive rapid temperature changes? Alumina ceramic has moderate thermal shock resistance. Sudden temperature shifts may cause cracks. Preheating the crucible gradually reduces this risk. Avoid placing hot crucibles directly on cold surfaces. Do alumina ceramics react with chemicals? Alumina is chemically inert in most environments. It resists acids, alkalis, and molten metals. Hydrofluoric acid and strong alkaline solutions at high temperatures may damage it. Check compatibility charts before use. What industries use alumina crucibles? Laboratories, metallurgy, and electronics rely on these products. They melt metals, analyze samples, and sinter materials. Semiconductor manufacturing uses them for wafer processing. Jewelers also employ alumina boats for casting precious metals.
