Alumina Boats Description

Alumina boats have high thermal conductivity, compressive strength, and thermal shock resistance. Alumina ceramics, as a fine technical ceramic material, are widely used in different types of industries. High-purity alumina has superb performance in electrical insulation, high chemical resistance, and low thermal expansion. High-purity alumina materials are excellent for making parts for CVD, ion implants, photolithography, and semiconductor parts. In traditional industries, alumina ceramics are ideal for products such as injector tubes, gas nozzles, and insulators. Alumina tubes are used as a protector for high-temperature thermal couples as well.

Alumina Boats Specification

Alumina Boats, made from aluminum oxide (Al2O3), are used across various fields due to their excellent thermal and chemical stability. In laboratories, they facilitate high-temperature furnace operations, chemical reactions, and thermal analysis. In material science, they aid in sample preparation and powder processing. Industrially, they are crucial for metallurgy, glass, and ceramics production. The semiconductor industry uses them for wafer processing, while the chemical industry employs them as catalyst supports. In environmental science, alumina boats are used for ashing samples to determine composition or contamination levels. Their high melting point, chemical inertness, and mechanical strength make them ideal for high-temperature and corrosive environments.
