Preparation of Aluminum phosphate or POLYPHOSPHATE particles related applications

摘要

Provided is a process for preparing a Pigment based on Amorphous Aluminum phosphate or POLYPHOSPHATE by reaction of Aluminum phosphate and SODIUM ALUMINATE. The Amorphous Aluminum phosphate or POLYPHOSPHATE is characterized by a Density less than 2.50 grams per Centimeter Cubic and a molar ratio of Phosphorus on Aluminum greater than 0.8.In a particular embodiment, the composition is useful for Substitute of Titanium dioxide in paintings.
