Why Has Alumina Crucible Become An Important Container For High-temperature Scientific Research And Industrial Melting?

Alumina crucible is a high-performance ceramic container made of high-purity aluminum oxide such as 92%, 95%, and 99% through precision molding and high-temperature sintering. It is widely used in laboratory analysis, metallurgical melting, and high-temperature treatment of new energy materials.

Different purity levels correspond to different usage requirements, among which 99% high-purity alumina crucibles can withstand high temperatures of 1700 ℃ for a long time, suitable for ultra-high temperature precision experimental scenarios. Its dense ceramic structure endows the product with excellent thermal shock resistance, making it less prone to cracking during repeated heating and cooling cycles, and its operational stability far exceeds that of ordinary refractory crucibles.

At the same time, alumina crucibles have excellent chemical stability, are resistant to acid and alkali corrosion, do not react with molten metal, and ensure maximum material purity. In addition, with its high dimensional accuracy and excellent insulation performance, it can not only meet the needs of small-scale sample baking in laboratories, but also support industrial scale high-temperature production.
