MnCO3 Dry Powder Fertilizer Raw Material , Less Impurity / Heavy Metal Nitrogen Based Fertilizer

Manganous Carbonate(MnCO3) of Feed Grade 

Basic Properties of this manganese carbonate dry powder :

It is a white amorphous powder. The air is easy oxidation and color becomes shallow brown. The relative density 3.125. Hot to 100 ℃ start decomposing to carbon dioxide and manganese oxide to 300 ℃ above is decomposed into carbon monoxide and manganese oxide of high prices. Insoluble in water and alcohol, soluble in dilute acids.

Molecular formula: MnCO3

CAS NO : 598-62-9

Appearance: White powder 

Manganese carbonate  is rosy triangle crystal or amorphous brown powder. Calcined in the pyrolusite powder direct acidification method, which can shorten process, lower cost and reduce pollution to environment; widely used in ferrite, desulfurizatio, porcelain glaze, varnish, manganese salt, fertilizers, pharmacy and machine parts and agriculture.

 We produce manganous carbonate both technical ( industry ) grade and electronic phosphorization grade,

 about  5000 tons every year.

7.Nature:
rosy rhombus crystal or formless light brown powder , relative density 3.125 .almost insoluble in water, but slightly soluble in water containing CO2. Soluble in dilute inorganic acid, slightly soluble in common organic salt, insoluble in liquid ammonia. Stable in dry air, wet easily oxidized to form manganese oxide gradually becomes black, heated hours of the liberation of the CO2, when water is azeotropic hydrolysis. The boiling potassium hydroxide, the formation of manganese hydroxide.
