CO2 removal with enhanced wollastonite weathering in …
Wollastonite powder removed CO2 in soils with pH values of 4.4, and 7.7, at 1.0 and 1.1 g C kg−1 soil, respectively. Wollastonite powder increases CO2 emissions in acidic soils, but these emissions are less than 20% of the total carbon removal by wollastonite weathering. CO2 emissions in acidic soils result from the acidolysis of CaCO3 within the wollastonite …

Wollastonite
Wollastonite's greater readiness to melt at higher temperatures has a curious side effect: Glazes can tolerate higher SiO 2 (from the Wollastonite) and melt just as well or better. In glass and fiberglass making wollastonite melts more readily (lower energy costs) and microbubble generation is lower than limestone-sand mixes.
