  • mechanochemistry of materials international fine

    A mixture of CaO and silica-gel (SiO2) was subjected to grinding using a planetaryball mill,followed by heating to investigate the temperature for synthesizing para-wollastonite (CaO·SiO2). TheMCtreatment of the mixture brings about amorphous aggregates with almost homogeneous chemical composition. 2-hoursMCtreatment enables us to synthesize para-wollastonite by …
