Features of solid phase synthesis of wollastonite from natural and technogenic raw material

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°C...

Summary: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°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.
