Abstract

A process for the preparation of Boehmite particulate material from the waste containing Aluminium chloride. Aluminium sulfate, Aluminium carbide or any other Aluminium salt; said process comprising : a. preparing 2 to 15 wt. % of aqueous slurry of Aluminium hydroxide, said Aluminium hydroxide is recovered from the waste containing Aluminium chloride, Aluminium sulfate, Aluminium carbide or any other Aluminium salt by hydrolyzing the waste with soda ash; b. preparing slurry containing 2 to 10 wt. % of silane and 2 to 10% of silica by making 2 to 10 wt. % of aqueous slurry of silane with stirring followed by adding 2 to 10 wt. % of micro fine precipitated silica powder having average particle size of 3μ and stirring the slurry over night at low speed; c. Mixing slurry obtained in step (a) into step (b) followed by subjecting the reaction mixture to hydrothermal treatment at temperature in the range of 90°C to 250° C for at least 4 hours; and d. collecting Boehmite particulate material by either centrifuging or filter pressing the reaction mixture or any other conventional means followed by drying the product by either spray drying or spin flash drying or any other conventional means and optionally pulverizing to get fine flaky particles with particle size 5 to 8 micron. Boehmite particulate matter having 80 to 84 wt % of Boehmite along with base material as micro fine precipitated silica powder (8 to 10 wt %) treated with silane (8 to 10 wt %) with preferred particles size 5 to 8 microns and a coating comprising thereof.
