: “ AN IMPROVED PROCESS FOR THE PREPARATION OF LOW APPARENT DENSITY AND BRIGHT WHITE ALUMINA TRIHYDRATE POWDER”
Application 1123/DEL/2000 published 2006-04-28, filed 2000-12-08
Aluminium metal in the form of powders, granules, thin sheets/foils and in the form of blocks were used as the source of aluminium component of aluminium trihydrate. Alkali metal hydroxides (typically in the concentration range 3-20%) were used as the other reactant. The reaction of the above two constituents was carried out to generate aluminate solution with alumina trihydrate precipitate and on hydrolysis of the above solution, alumina trihydrate was completely precipitated. The precipitate was filtered and dried at 1100C to generate free flowing powder.
