应用
Magnesium carbonate hydroxide hydrate is used as drier, color ficatives, anticaking agent, carrier, swelling agent, acidity regulator. Magnesium carbonate is the production of magnesium oxide by calcining. Magnesite and dolomite minerals are used to produce refractory bricks. MgCO3 is also used in flooring, fireproofing, fire extinguishing compositions, cosmetics, dusting powder, and toothpaste. Other applications are as filler material, smoke suppressant in plastics, a reinforcing agent in neoprene rubber, a drying agent, a laxative to loosen the bowels, and color retention in foods. In addition, high purity magnesium carbonate is used as antacid and as an additive in table salt to keep it free flowing.

备注
It should be stored in a dark, dry and ventilative warehouse, kept away from water and moisture

产品说明

一般描述

Magnesium carbonate basic (Magnesium hydroxy carbonate) is a magnesium salt. It has been synthesized by reacting magnesium hydroxide and carbon dioxide.

应用

Magnesium carbonate basic may be employed for the isolation of carotenoids from grapes during the quantification of carotenoids in grapes by reversed-phase C₃₀(RP-30) HPLC-DAD-MS (ESI⁺) (High-performance liquid chromatography-diode array detection-mass spectrometry with electrospray ionization) analysis.
