Abstract

CaMgSi₂O₆ gels using a mixture of each individual metal alkoxide were prepared by sol-gel method adding hydrochloric acid with various concentration as a catalyst. The crystallization of CaMgSi₂O₆ (diopside) by heating the gels at various temperatures was investigated using X-ray diffraction. Hydrochloric acid concentrations above 3mol is found to be suitable.
