95% aluminium hydroxide Al(OH)3 Powder For Industry with good price
1. Aluminum Hydroxide, archaically called hydrate of alumina or alumina trihydrate (Al2O3•3H2O), which is a non-abrasive powder with a Mohs' hardness index of 2.5 - 3.5 and a specific gravity of 2.42. It can be heated to 200°C and hydrated alumina can be decomposed into 66% alumina and 34% water.
2. Aluminum hydroxide is white powder product. Its appearance is white crystal powder, non- toxic and odorless, with the characteristics of good flowability, high whiteness, low alkali and low iron. It is an amphoteric compound. The main content is AL (OH) 3.
