MgCO3 CAS No 2090-64-4 Medical grade magnesium carbonate used in
Food grade magnesium carbonate mainly used for flour ameliorant. In formula of flour ameliorant,
magnesium carbonate is very important auxiliary parts. It’s mainly
is to improve dispersibility and mobility. MgCO3 content in flou r
ameliorant is about 10%-15%. In order to get better mobility, MgO
content should be about 40% - 43%, moisture should be less than 1%,
specific volume should around 1.4-2.5 ml/g. In addition, it is also
used in food, cosmetic and medical industries.

Shanghai liangjiang titanium white product Co., LTD is the leading Heavy Magnesium Carbonate Manufacturer, engaged in the supplying of a premium quality Heavy
Magnesium Carbonate as per the requirements of the clients. Our
Heavy Magnesium Carbonate is highly popular among the clients for
their unique properties and applicability in various industrial
applications.1, This product is a white granular power, odourless, almost
tasteless. This product is not soluble in water or ethanol, but it
can make water have a weak alkaline, can soluble and effervescence
in dilute hydrochloric acid. Its small volume makes it easily to be
modulated into powder, it is often used in producing medicine for
stomach illness and duodenal ulcer. In addition, it also can be
used in producing advanced glass, magnesium oxide, cosmetics,
toothpaste, fireproofing paint etc.
2, Liangjiang brand – heavy magnesium carbonate, mainly used as medical intermediate, antacid, color fixative,
carrier, anticaking agent; food filler, magnesium compensator; also
can be used as filler and fortifier for rubber products, heat
resisting fireproofing material. It is widely used in many
industries, electric wire, magnesium salt, pigments, paints, daily
cosmetics, shipbuilding, boiler producing, sports etc.
3, Liangjiang brand Heavy magnesium carbonate manufacture process:
Manufacture process of MgCO3, is different based on different route
of raw materials. The process is divided into bittern-sodium
carbonate method and magnesia double decomposition method.
1. bittern-sodium carbonate method: Firstly, make pretreatment of bittern and sodium carbonate
solution, precipitin reaction, filtration, dehydration, dry, smash
and other process to get medical magnesium carbonate.
2. magnesia double decomposition method: take advantage of ammonium sulfate and magnesia to make double
decomposition, get magnesium sulfate solution. And then get
carbonizing ammonium hydroxide from recycled ammonia, mix it with
magnesium sulfate solution to get basic magnesium carbonate.
Through filtration, dehydration, dry, smash and other process to
get medical magnesium carbonate.
we aspires to be the supplier of the world's leading chemical raw
materials, show our value of the products made in China!
