It is a white crystalline solid or crystalline powder, with no odour. It is insoble in water and ethanol but soluble in olefine acid solvent, with the solvent alkalescence. Beside, it is stable in air and could decompose to magnesium oxide under the heating of 700℃. And its categories are as the following: norganics;Pharmacopoeia (USP);Pharmacopoeia A-ZPharmacopoeia (USP);Pharmacopoeial OrganicsEssential Chemicals;Routine Reagents;USP.
As for its usage, it has wide application in many fields. Firstly, it could be used in the medicine to neutralize gastric acid and cure duodenal ulcer. Secondly, it could be used in the rubber industry to be as the rubber filler. Thirdly, it could be used in making the magnesium oxide,fire retardant coating,printing ink,glass,toothpaste and also be used in the food as flour improvers and bread calcium acid phosphate.
Beside, as it is toxic, while using, we should avoid contacting with skin and eyes and do not breathe dust. When you store it, you should keep it in a cool, ventilating, and dry place. If you want to produce this chemical in lab, you could use the following chemical reaction:MgSO4+Na2CO3→Na2S04+MgCO3↓
