The difference between talc and calcium carbonate. 3, Talc has a nuclear role in polypropylene, and calcium carbonate in this respect effect is not obvious. 4, calcium carbonate can generally be divided into light calcium carbonate and heavy calcium carbonate, and talc does not distinguish between talcum powder from natural minerals in the flour.

During trials using 4 different additives, Natural Silica, Synthetic Silica, Talc, and Calcium Carbonate it was found that irregularly shaped Silica and Talc outperform the smaller, more spherical particles of Calcium Carbonate. In addition, much higher dosage levels of 250-300% are required to achieve performance equivalent to Silica or Talc.

Calcium supplements are generally made with one of two sources of elemental calcium: either calcium carbonate or calcium citrate. Calcium carbonate, the form of calcium found in Caltrate, is the most concentrated form and is commonly found in food and drug stores. Most formulas supply calcium in the form of calcium carbonate.

Kaolin. 2. Talc. 1. Looking at a pile of kaolin powder and a pile of talc powder, however, you will notice an obvious difference. The talc is much whiter (unless it is very impure). If you put your hand into the powder, you will find that although the kaolin makes your hand white and dusty, the talc sticks to it like blazes.
