99.5 Alumina Ceramic Crucible

Alumina ceramic crucible is a type of crucible made from alumina (Al₂O₃) as the main raw material through processes like mixing, shaping, and high-temperature sintering.

It features excellent properties such as high temperature resistance (can withstand temperatures up to 1600-1800°C depending on alumina content), good chemical stability (resistant to corrosion by most acids, alkalis, and molten metals except strong alkalis and hydrofluoric acid), high mechanical strength, and low thermal expansion coefficient.

Widely used in laboratories and industrial fields for operations like melting, calcining, and sintering of various materials, it is a common high-temperature reaction container.
