Alumina/Silica Cylindrical Crucible (Al₂O₃85/SiO₂15)

Alumina/Silica Cylindrical Crucible (Al₂O₃85/SiO₂15) combines high-purity alumina with silica to deliver excellent high-temperature stability, thermal shock resistance, and mechanical strength. The unique two-phase microstructure, primarily composed of α-Al₂O₃ and mullite (3Al₂O₃·2SiO₂), offers exceptional creep resistance and the ability to retain over 90% of its room-temperature tensile strength at elevated temperatures. This makes it ideal for use in demanding industries such as glass manufacturing, metallurgy, semiconductor processing, and advanced ceramics production. Specific applications include high-purity metal casting, glass melting at temperatures exceeding 1500 °C, and chemical reaction containment in corrosive or oxidative environments. Its reliability in extreme thermal cycling environments makes it invaluable in research on advanced refractory materials and industrial process optimization. The crucible’s resilience under intense operational demands underscores its role as a key enabler of scientific experimentation and precision manufacturing in high-tech sectors.
