Abstract

White pigment based on hydrated calciumsulphoaluminate, has the following physical data- pH value 10.6; dried solid material at 20 degrees C 31% by weight; dried solid material at 105 degrees C 21.9% by weight; viscosity 50 centipoises; particles size distribution 75% of particles of less than 8 mu; and an X-ray diffraction spectra corresponding to the formula 6 CaO, Al2O3, 3 SO3- 31H2O. In an example chalk was stirred with water a solution of aluminium sulphate added, trisodium citrate added as dispersing agent and the product passed through a sieve with openings of 80 mu. Other dispersing agents may be used as starch, protein, polyacrylates, etc.
