Magnesium Carbonate

magnesium carbonate

[mag′nē·zē·əm ′kär·bə‚nāt] (inorganic chemistry) MgCO₃ A water-insoluble, white powder, decomposing at about 350°C; used as a refractory material.

Magnesium Carbonate

MgCO₃, a salt; colorless crystals. Density, 3.037 g/cm³. The decomposition of magnesium carbonate into MgO and CO₂ is partial at 500°C and complete at 650°C Its solubility in water is low (22 mg/l at 25°C) and decreases with increasing temperature. Upon saturation of an

aqueous suspension of MgCO₃ with CO₂, the MgCO₃ dissolves because of the formation of the hydrocarbonate Mg(HCO₃)₂. Basic magnesium carbonates are extracted from aqueous solutions in the absence of excess CO₂. Magnesium carbonate interacts with metal carbonates to form double salts, an example of which is the natural mineral dolomite, MgCO₃,CaCO₃. Magnesium carbonate is widespread in nature in the form of the mineral magnesite. Basic magnesium carbonate, 3MgCO₃,Mg(OH)₂,3H₂O, is used as a filler in rubber mixes, in the manufacture of thermal-insulation materials, and in medicine (as a tooth-powder ingredient and internally to counteract increased acidity).

magnesia insulation

Magnesium carbonate hydroxide, with or without admixture of fiber reinforcement or other materials; a good thermal insulator because of the great number of closed air cells it contains; molded into rigid boards, blocks, or shapes conforming to piping.

magnesium carbonate

magnesium

(Mg) [mag-ne´ze-um] a chemical element, atomic number 12, atomic weight 24.312. (See Appendix 6.) Its salts are essential in nutrition, being required for the activity of many enzymes, especially those concerned with phosphorylation" >oxidative phosphorylation. It is found in the intra- and extracellular fluids and is excreted in urine and feces. The normal serum level is approximately 2 mEq/L. Magnesium deficiency causes irritability of the nervous system with tetany, vasodilation, convulsions, tremors, depression, and psychotic behavior.

Homeostasis of magnesium in extracellular fluids. The normal serum magnesium level is regulated by intestinal and renal function. Most of the body's magnesium is stored in bones, muscle, and soft tissue.
