Feature description

Magnesium carbonate is a white monoclinic crystal or amorphous powder. It is non-toxic and stable without taste. Relative density 2.16. Slightly soluble in water,

The solubility of aqueous solution is 0.02% (15 ℃).

instructions

Magnesium carbonate is soluble in acid and ammonium solution. It is easy to decompose into magnesium oxide and carbon dioxide during calcination. In case of dilute acid, decompose and release two

Carbon oxide. Generally, it is slightly soluble in water. When heated, it is easy to react with water (when hard water softens) to produce magnesium hydroxide (because of hydrogen oxidation

Magnesium is more insoluble than magnesium carbonate. Equation: MgCO3 + H2O = Mg (OH) 2 + CO2

Packing list

Magnesium carbonate products are covered with plastic film bags, lined with plastic bags, double-layer packaging, which can effectively avoid product transportation

The rain was wet in the process.

In addition, according to customer demand, this product can also be packed in kraft paper and barrel. Customers can also choose whether to use pallet or not

packing.

Purpose / application area

In addition to being used as raw materials for electronic components, magnesium carbonate is also used to prepare high-purity magnesium oxide, advanced ink, fine ceramics, medicine

Cosmetics, toothpaste, advanced pigments and other important raw materials.
