Corundum Mullite Combination Sagger Crucible Alumina Ceramic Zirconia Sintering Crucible for Scientific Research and Experiments (1, 230×230×40mm)

Specification: length, width, height, internal height, wall thickness, opening height as shown, alumina content > 90%, operating temperature ≤ 1700 ℃. AI2O3 (%): 91, SiO2 (%): 8.5, Fe2O3 (%): 0.06, Na2O + K2O (%): ≤0.03, Service Temperature (°C): ≤1700, Flexural Strength at 1400°C (Mpa): 16.5, Thermal Expansion Coefficient at 1000°C (10⁻⁶): 6, Apparent Porosity (%): 17, Bulk Density (g/cm³): 3. Corundum mullite crucibles are more resistant to high temperature and rapid cooling and heating than ordinary ceramic crucibles, with Mohs hardness grade 9, ultra-low coefficient of thermal expansion, high structural strength and thermal stability. Applications: Ceramic substrates, substrate sintering, ceramic tools, semiconductors, aerospace, research, etc. The first use is recommended to empty firing 1-2 times to remove moisture and impurities, so as not to affect the quality of the product firing.
