The crystallisation of alcaline‐earth metal metalsilicates was studied by slow cooling of saturated solutions in the metal chloride melts at T 0 = 830° to 1300°C, down to ambient temperature; cooling rates were varied from 20° to 200°C hr −1 . Calcium metasilicate crystallised as β‐CaSiO 3 prisms, strontium metasilicate as α‐SrSiO 3 platelets and barium metasilicate as α‐BaSiO 3 platelets. Final crystal lengths increased with reduction in cooling rate and with increase in initial crystallisation temperature.
