摘要 |
Method for the production of a finely crystalline boehmite and application of said boehmite as flame retardant in plastics. The method involves mixing aluminum monohydrate with a boehmite crystal structure in water to form an aqueous dispersion of said aluminum monohydrate in said water, and then grinding the dispersion while maintaining the dispersion in a pH range of 2 to 4 and forming boehmite seed crystals. The boehmite seed crystals can then optionally be mixed with a hydrate and a basic aqueous solution to form a dispersion which may be heated to convert at least a substantial portion of the aluminum monohydrate to boehmite. |
