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.
According to different applications of magnesium carbonate, it can
be divided into industry grade MgCO3, food grade MgCO3, medical
grade MgCO3, transparent MgCO3, electrical grade MgCO3, bulk MgCO3
and aciculiform MgCO3 etc.
Light magnesium carbonate is widely used in many fields. In pigments, paints and printing
ink industries, MgCO3 can be used to produce high purity magnesium
compound. MgCO3 also be used in fireproofing, extinguishant, floor
and insulating material industries. In plastic and rubber
industries, MgCO3 is used as filler and smoke inhibitor. In
addition, in glass, ceramics and chemical medicine producing, MgCO3
also can be used in little. CPU grade MgCO3 can be used as salt
additive, antacid in toothpaste and biscuits.
Medical grade MgCO3 can be used as antiacid. Antiacid is used for
hyperacidity and duodenal ulcer in clinic. Because of small volume,
it is suit for compounding powder.
In food industries, it is used for flour ameliorant, and content
reaches 10%-15%, for improve dispersibility and mobility. In
addition, it also can used in producing magnesium salt, magnesium
oxide, fireproofing material, rubber, ceramics, glass, cosmetic,
toothpaste, and pigments etc.
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
Electronic grade MgCO3 is used as materials for electronic
components. Besides, it is also main material for producing high
purity MgO, printing ink, fine ceramics, medicine, cosmetics,
toothpaster, advanced pigments etc. It has the highest additional
value when used in electronic materials.
Transparent light MgCO3 mainly used as filler and fortifier in
transparent or light-colored rubber products. It almost no change
for rubber’s refractive index, but can enhance abrasive resistance,
resistance curve and strength of extension. It also can be used as
filler in paint, ink and coatings, toothpaste, medicine and
Aciculiform MgCO3, mainly used as filler and fortifier in rubber.
Easily to combine with rubber because of its aciculiform crystal.
It has similar refractive index with rubber if well controlled its
ratio of particle size and length. It can enhance abrasive
resistance, resistance curve and strength of extension. It also can
be used as filler in paint, ink and coatings, toothpaste, medicine
Bulk magnesium carbonate is same with light grade magnesium
carbonate, the difference is only form. It only can be used for
athlete to keep hand dry.
we aspires to be the supplier of the world's leading chemical raw
materials, show our value of the products made in China!
