Introduction:

Alumina Crucible is made of raw material aluminum oxide. Alumina is a ceramic material with high thermal conductivity, compressive strength, high-temperature resistance, and thermal shock resistance.

It also has a low thermal expansion, making it a suitable material for furnace use in the crucible, tube, and thermocouple sheath form. Alumina is high hardness and good wear resistance, making it a suitable material for ball valves, piston pumps, and deep drawing tools.
In addition, it can be easily combined with metals and other ceramic materials using brazing techniques and metalizing.Alumina Crucible is made of raw material aluminum oxide.Alumina is a ceramic material with high thermal conductivity, compressive strength, high-temperature resistance, and thermal shock resistance. It also has a low thermal expansion, making it a suitable material for furnace use in the crucible, tube, and thermocouple sheath form.

Alumina crucibles are essential tools in high-temperature applications, widely used in laboratories and industrial settings. Made from high-purity aluminum oxide (Al₂O₃), these crucibles exhibit exceptional thermal stability, chemical resistance, and mechanical strength.
They can withstand extreme temperatures up to 1750°C, making them ideal for processes such as melting, sintering, and analyzing materials. Their excellent resistance to acids, alkalis, and corrosive substances ensures durability and reliability in harsh environments. Alumina crucibles are commonly employed in metallurgy, ceramics, chemistry, and materials science research, providing a robust and inert container for high-temperature experiments and processes.

Application

Ceramics: Sintering and firing ceramic materials. Chemistry: Chemical analysis and reactions with corrosive substances. Materials Science: Synthesis and testing of advanced materials. Research and Development: High-temperature experiments and thermal analysis in labs.
