magnesium carbonate properties:White monoclinic crystal or amorphous powder. Non-toxic, tasteless and stable. Relative density 2.16. Slightly soluble in water, the aqueous solution is weakly alkaline, and the solubility in water is 0.02%(15 ℃). Soluble in acid and ammonium salt solution. When calcined, it is easy to decompose into magnesium oxide and carbon dioxide. When it meets dilute acid, it decomposes and releases carbon dioxide. Generally slightly soluble in water.

Molecular formula:xMgCO3·yMg(OH)2·zH2O 4MgCO3·Mg(OH)2·4H2O

CAS NO:39409-82-0

magnesium carbonate appearance:White monoclinic crystal or amorphous powder, non-toxic, odorless, stable in air.

Magnesium carbonate first aid measures 同题参见

Skin contact to remove and isolate contaminated clothing and shoes. For a small amount of skin contact, avoid the material spread area. Keep the patient warm and quiet. 更多阅读

Eyes in contact with magnesium carbonate If the skin or eyes come into contact with the substance, rinse immediately with water for at least 20 minutes.

Inhalation of magnesium carbonate patients to fresh air, see a doctor. If the patient stops breathing, artificial respiration is given. Do not use mouth-to-mouth artificial respiration if the patient has ingested or inhaled the substance; use a one-way valve small respirator or other appropriate medical respirator. If breathing is difficult, give oxygen.

Inhalation, ingestion, or skin contact with the substance may cause a delayed reaction. Ensure that medical personnel understand the knowledge of individual protection related to the substance and pay attention to self-protection.

Fire protection measures for magnesium carbonate

Hazardous characteristics react with formaldehyde and acid contact, carbonate is not compatible with calcium, lead diacetate, mercurous chloride, silicon, silver nitrate, titanium zinc acetate.

If the substance or contaminated stream enters the waterway, notify downstream users of potential water contamination, notify local health, fire and pollution control departments, and use water, dry powder, foam, and carbon dioxide to extinguish the fire.

Use of magnesium carbonate

1. Used in the manufacture of magnesium salt, magnesium oxide, fire retardant coating, ink, glass, toothpaste, rubber filler, etc., used in food as flour improver, bread leavening agent, etc.

2. Magnesium carbonate and gastric acid medicine, for gastric and duodenal ulcer.

3. Alkaline agent, desiccant, color protection agent, anti-caking agent, carrier, leavening agent and acidity regulator. EEC is permitted for: table salt, powdered sugar, acidified cream, milk, ice cream, biscuits. For the preparation of chemical leavening agent. Residues in food should not exceed 0.5 percent. Magnesium carbonate is used to prevent salt agglomeration, adding 0.1 to 0.3.
