Taguchi's method was applied to investigate the effect of main high energy ball milling (HEBM) parameters: milling time (MT), ball to powder weight ratio (BPWR), and milling speed (MS) on the CaCO3 crystallite size. The settings of HEBM parameters were determined by using the L9 (33) orthogonal experiments array (OA). The as-received …Web

When calcium carbonate reacts with water that has dissolved carbon dioxide, it forms a calcium bicarbonate. As new cold water with dissolved calcium carbonate is added and heated, the process continues. In this process, the CO 2 gas is removed repeatedly, and the carbonate concentration increases, and thus more …Web
