Solid phase synthesis of wollastonite based on naturaldiatomite, opoka, marshallite) and technogenicmicrosilica, and anhydrous silicic acid) silica raw material is studied. A definite effect is established for the nature of silica raw material on wollastonite synthesis in the range 1000-1200°C. The most complete synthesis occurs with use of finely dispersed amorphous silica, in the form of microsilica, independent of the nature of the calcium-containing component.
