Dispersible alpha alumina monohydrate |
| abstract |
An alpha alumina monohydrate, AlO(OH), powder is produced which is capable of readily dispersing in aqueous solutions to yield a shear-rate thinning mixture. The alpha alumina monohydrate is made by reacting an acid reactant and a base reactant, wherein at least one contains aluminum, in an aqueous medium in proportions to yield a solution having a pH of from about 7.5 to 10. Then the mixture is given the unique heat treatment at a temperature of from about 60 DEG to 100 DEG C. for a period of from about 2 to 7 hours. The excess water is removed from the product such as by filtration. The solid can be optionally washed to remove by-product salts. The solid product can be readily redispersed in water to yield a shear-rate thinning liquid without the aid of any further acid or base or the use of excessive high shear mixing. The solid product can be further dried to recover a solid product with greater than 10% AlO(OH) and even greater than 35% AlO(OH). |
