Chemical Name: Magnesium carbonate , Basic Magnesium carbonate
Molecular Formula: xMgCO3·yMg(OH) 2·nH2O
CAS: 39409-82-0
Character:. Magnesium Carbonate occurs as light, white, friable masses,or as a bulky, white powder. It is a basic hydrated magnesium carbonate or a normal hydrated magnesium carbonate. It is stable in air. It is practically insoluble in water, to which,however, it imparts a slightly alkaline reaction. It is insoluble in alcohol, but dissolves, with effervescence, in dilute acids.
Uses: pH control; drying agent; color-retention agent;anticaking agent; carrier.
