Calcium Carbonate, Calcite (CaCO3) ScienceDirect

1997-1-1  Calcite or calcspar is the mineral name of the low-pressure, hexagonal form of calcium carbonate, CaCO3. It is observed that calcite is the principal constituent of limestone, marble, and chalk. The mineral Iceland spar is a pure, colorless, optical quality form of calcite. The significant optical feature of calcite is its very high

Calcium Carbonate an overview ScienceDirect Topics

Calcium carbonate (also known as chalk), mined as calcite, is the most commonly used filler for PVC. It is discussed in detail in Section 8.4.1 . It is usually surface treated with stearic acid, producing a layer of calcium stearate on the filler surface.

Calcite an overview ScienceDirect Topics

Calcium carbonate in the form of calcite has been used as filler in the construction industry for a very long time. The addition of calcite is beneficial to cement and concrete properties due to the fact that it can chemically react with the tricalcium aluminate (C 3 A) phase in PC to form monocarboaluminate (C 4 AĈH 11 where Ĉ stands for CO
