High Purity Aluminum Hydroxide

2019-07-07 admin
By the Bayer process, we produce High Purity Aluminum Hydroxide (Gibbsite) which is a white powder with about 20% of the water, this prevents the powder from flying in your processing process.
The purity of this series is with 99.9% and 99.99%, and metal impurities such as iron are extremely low.
 
AH-3N product introduction: Appearance is white crystal powder, uniform particle size, high purity, stable chemical properties, good crystal phase stability, and good sintering activity. It’s the excellent raw material for the preparation of optical glass additives and high-purity aluminum salts.
 
AH-4N product introduction: Appearance is white crystal powder, uniform particle size, high purity, stable chemical properties, good crystal phase stability, and good sintering activity. It’s the excellent raw material for the preparation of high purity activated alumina, petroleum, chemical catalyst, lithium ion battery and other industries.
