Abstract

Mfr. of a fine white filler for use in industry, viz. ettringite, calcium trisulphoaluminate 3CaO, Al2O3, 3CaSO4, 32H2O (I), by hydrating at 20-90 degrees C, a mixt. of calcium aluminate, calcium sulphate and water, as in Parent Patent, is improved by hydrating at 20-100 degrees C a mixt of a product contg. calcium silicate, pref. Portland cement and a product contg. calcium aluminate, pref. an alumina cement, plus calcium sulphate, e.g. powdered gypsum, with stirring for sufficient time to obtain a mixed cpd. contg. 69-98 (I), 31-2% tobermorite and 0-4% hydrated silica as SiO2. The pref. uses are as a filler for the paper-making and paint mfg. industries.
