ABSTRACT:
A crystalline zinc silicate mineral of the sauconite, hemimorphite or willemite type is prepared by subjecting an acid-treated product of a clay mineral and an oxide or hydroxide of zinc or a compound capable of forming this oxide or hydroxide under reaction conditions to a hydrothermal treatment. This crystalline zinc silicate mineral has a fine and uniform particle size and is excellent in the pigmenting characteristics.
