Abstract

PURPOSE: To obtain petallike calcium silicate with high bulk specific vol. and high oil absorbing capacity by adding calcium salt to alkali silicate in a specified excess amt. to the slkali followed by reaction under specified conditions.
CONSTITUTION: To alkali silicate are added 1.05W1.4 times as much calcium salt as the alkali contained by eq., and they are reacted at 150W250°C in the presence of 5W100 times as much solvent as the resulting calcium silicate by wt. according to the equation (where R is Na or K, X is an anionic radical forming salt by combination with Ca, e.g. Cl2 or (NO3)2, m is a positive no. and n=0.1W10), thus obtaining petallike calcium silicate to which amorphous silicon dioxide is added in formation of gyrolite type calcium silicate of 2CaO.3SiO2.nSiO2.mH2O.
