MANGANESE CARBONATE MANGANOUS CARBONATE
Manganese carbonate is widely used as an additive to plant fertilizers to cure manganese deficient crops. It is also used in health foods, in ceramics as a glaze colorant and flux, and in concrete stains. It is used in medicine as a hematinic.
PROCESS OF MAKING MANGANESE CARBONATE WHICH COMPRISES PREPARING A SOLUTION, FREE FROM SOLID PHASE, OF MANGANOUS OXIDE IN AN AQUEOUS SOLUTION OF AT LEAST 200 GRAMS PER LITER OF NH3 AND AN AMMONIUM SALT OF AN ACID FORMING A SOLUBLE MANGANESE SALT, SAID MANGANESE-CONTAINING SOLUTION CONTAINING COMBINED CARBON DIOXIDE IN ...
Manganese carbonate is known to decompose readily on heating in air or under a reduced pressure of 10P5 Torr at moderate temperatures (300-400°C) yielding MnO, which dissociates simultaneously to form Mn,O, [l-4].
