Product FAQ's
Alumina crucibles are prized for high-temperature work in metallurgy, ceramics, chemical processing, and materials testing. Their purity and strength let you melt, calcine, or sinter samples without contamination, making them a staple in both lab and industrial furnaces.
Depending on purity and wall thickness, alumina crucibles can safely handle up to 1700 °C (3092 °F). High-grade ceramic versions resist thermal shock and chemical attack, ideal for demanding refractory applications.
Fine aluminum oxide powder (Al₂O₃) is shaped—cylindrical, boat-style, rectangular tray style or other—and then sintered at very high temperatures to produce a dense, durable ceramic vessel.
Alumina Crucibles are available in a purity range from 85% to 99.8% alumina. Typically grades of ≥99.5% are recommended for analytical or semiconductor work to minimize contamination and boost chemical resistance.
Gently remove loose debris by tapping or brushing.
Heat in a furnace or kiln to burn off organic residue.
Use non-abrasive ultrasonic baths or soft brushes for cleaning.
Avoid strong acids or harsh abrasives that can erode the ceramic.
Routine, gentle maintenance preserves integrity and ensures consistent results.
Alumina crucibles are available in various shapes to suit different applications, including cylindrical, conical, rectangular, boat-shaped and customised designs. These shapes are chosen based on the specific heating and material handling needs of laboratories or industrial setups.
Trusted alumina ceramic tube suppliers in the USA, such as M-Kube Enterprise, also offer custom alumina crucible shapes and sizes to meet unique requirements. With their expertise in high-temperature ceramic solutions, M-Kube Enterprise provides high-purity alumina crucibles tailored for durability and precision in demanding environments.
