WhatsApp Calcium carbonate is an inorganic chemical compound with the chemical formula CaCO 3. Calcium carbonate is one of the most popular chemicals which is first encountered in school classrooms, where the use of chalk (a form of CaCO3) is found. It is found in the earth''s crust. It is also found in many forms such as marble, limestone, etc.

Separate the CaCO3 from the SiO2. The solid mixture of CaCO3 and SiO2 on the filter paper will be separated by chemically reacting the CaCO3 to form soluble CaCl2. The SiO2 will remain behind as a solid. The solid must first be transferred to a container of known mass. Preweigh a clean, dry evaporating dish.

Abstract A new CaCO3SiO2 composite with coreshell structure was successfully prepared by mechanochemistry method (MCM). SEM and FTIR indicated that SiO2 particles were homogeneously immobilized on the surface of CaCO3. The well dispersion of this CaCO3SiO2 composite into silicone rubber can not only reduce the usage amount of SiO2, but also improve the mechanical properties of silicone rubber.
