With this process for preparation of synthetic β- wollastonite a degree of purity between 92% and 97% is obtained for the synthesized product, from quartz, calcite and diatomite, with addition of lithium carbonate or sodium carbonate acting as mineralizers. The work cycle involves two stages: the 1st, in which the maximum temperature level, between 1050 degree C and 1150 degree C, is attained after 30 minutes of rapid heating, and the 2nd, in which said level is maintained for two to three hours.
