BOEHMITE | CAS 1318-23-6

Product Overview

Boehmite (CAS: 1318-23-6) is an aluminum oxide hydroxide mineral with the chemical formula AlO(OH), belonging to the orthorhombic crystal system. It is a white to off-white crystalline powder that serves as a key precursor for the production of various alumina phases and is widely used as a functional filler, catalyst support, flame retardant additive, and coating material across multiple industries.

Product Description

Boehmite is a white, free-flowing hydrated alumina powder with a boehmite crystal structure. It is a high-temperature resistant aluminum oxide-hydroxide that exhibits excellent thermal stability up to approximately 500°C before undergoing phase changes. The material is insoluble in water but soluble in strong acids and hot alkali solutions. Boehmite can be easily dispersed in monovalent acid solutions such as nitric acid and acetic acid, achieving stable dispersion concentrations up to 25% by weight.

Boehmite is a major component of bauxite ore and serves as an important chemical raw material. Its unique crystal structure and high purity make it an excellent precursor for preparing various alumina phases widely used in ceramics, electronics, adsorption, and catalysis applications.
