Manufacture of Synthesis Wollastonite

Synthetic wollastonite a calcium silicate has received much attention over the last decade. It is largely chemically inert and biologically safe. Due to its immense properties, the production capacity has increased substantially in recent years. Synthesis of wollastonite was investigated with regard to optimum parameters at laboratory scale; such as mesh size of raw material, (calcium carbonate, silica) time duration, sintering temperature, stoicheiometric ratio and characterization of product. It was found that wollastonite may be synthesized at maximum degree with varying sets of parameters. The maximum yield of the product with ratio 26: 15 for one hour was suitable to produce commercially acceptable product which is economically feasible.
