The difference between oyster shell powder and stone powder


Oyster shell powder and lime powder are both white powders, and it is difficult to distinguish their molecular sizes with the naked eye, so they feel similar, but the molecular size of oyster shell powder is much smaller than that of stone powder. It is processed by this process and has a high degree of fineness, while the molecules of stone powder cannot meet the standard.

The main components of oyster shell powder are calcium carbonate and chitin, and also contain a small amount of amino acids and polysaccharides. Stone powder is a white powdery substance with calcium carbonate as the main component. It does not contain chitin and has a certain amount of metal elements. Chitin can effectively inhibit bacteria, so stone powder has no such effect.

Oyster shells contain calcium carbonate, which is one of the essential mineral elements for the body and is mainly involved in the formation of bones and the balance of body fluids. Common stone powder and oyster shell powder in the market. Stone powder contains heavy metals, but oyster shell powder does not, stone powder contains magnesium, but oyster shell powder does not.
