Calcium carbonate - Wikipedia

The main use of calcium carbonate is in the construction industry, either as a building material, or limestone aggregate for road building, as an ingredient of cement, or as the starting material for the preparation of builders' lime by burning in a kiln. However, because of weathering mainly caused by acid rain, calcium carbonate (in limestone form) is no longer used for building purposes on its o

Calcined kaolin - why use it? - Serina Trading

Using calcined kaolin as a filler in rubber and plastics helps impart tensile strength. Hence it is a reinforcing filler instead of being non-reinforcing like hydrous kaolin. The fire-resistant property of calcined kaolin plus the fact that it is an electrical insulator is especially useful in the plastic covering of electric cables. It also imparts uv-resistance which is why it is often added ...

Kaolin vs Calcium Carbonate - Serina Trading

This meant calcium carbonate could not be used as filler because it would dissolve. Now most paper mills have gone over to alkaline sizing. Thus calcium carbonate now beats kaolin as the main filler for paper. Calcium carbonate is preferred for paper because it is much whiter than kaolin. Its ISO-Brightness is usually 96%, compared to around 83% for a typical kaolin. Quite a
