Aluminium Oxide Boats Description
Aluminium oxide boats possess high thermal conductivity, compressive strength and resistance to temperature fluctuations. Tonerdekeramik is a fine technical ceramic material that is extensively used in various industrial sectors. High-purity aluminium oxide is characterised by its high electrical insulation, high chemical resistance and low thermal expansion. High-purity aluminium oxide materials are well suited for the manufacture of components for CVD, ion implantation, photolithography and semiconductor parts. In conventional industry, aluminium oxide ceramics are utilised for products such as injection tubes, gas nozzles and insulators. Aluminium oxide tubes are also employed as protection for high-temperature thermocouples.
Aluminium Oxide Tubes Specifications
Aluminium oxide tubes, fabricated from aluminium oxide (Al2O3), are employed in various fields owing to their high thermal and chemical stability. In laboratories, they facilitate the operation of high-temperature furnaces, enable chemical reactions and thermal analyses. In materials science, they assist in sample preparation and powder processing. In industry, they play a critical role in metallurgy, glass and ceramic production. The semiconductor industry utilises them for wafer processing, whilst the chemical industry employs them as catalyst carriers. In environmental science, ceramic boats are used for the ashing of samples to determine composition or contamination levels. Given their high melting point, chemical inertness and mechanical strength, they are suited to high-temperature and corrosive environments.
