· As the main raw material for ceramics and coatings, black talc contains high contents of organic carbon and quartz, which deteriorates the whiteness and purity of calcined talc. In this work, calcined talc powders with high whiteness and purity have been prepared by the milling and reactive calcination of black talc with magnesium precursors.
