摘要：
Solid phase synthesis of wollastonite based on natural (diatomite, opoka, marshallite) and technogenic (microsilica, 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 degrees 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.
