The resulting products are investigated employing XRD and SEM techniques. β-wollastonite was obtained at 1050 ◦C and transformed to pseudowollastonite (α-CaSiO3) at 1150 ◦C. Physical and thermal properties have been evaluated. The batch sintered at 1250 ◦C showed the highest value of density of about 1.98 g/cm3 with high shrinkage rate as compared with other batches. The results also revealed that thermal expansion coefficient is more compatible with results obtained from natural wollastonite.
