1、Chemical Name: Magnesium Carbonate
2、Molecular Formula : xMgCO3·yMg(OH) 2·zH2O
3、Molecular Weight : 无水:84.31;碱式:485.65;一水:102.33
4、CAS: 无水:546-93-0;碱式:39409-82-0;一水:23389-33-5
5、Character: Magnesium carbonate (light density) is white, friable masses or unconsolidated white odorless powder. Relative density is 2.2 and melting point is 350℃. It’s stable in air. When heated to 700℃, it decomposes to carbon dioxide and magnesium oxide. It’s almost insoluble in water, but it imparts a slight alkaline reaction. It is insoluble in ethanol, but dissolves in dilute acids with effervescence.
6、Usage: It can be used as nutrient, flour treatment agent, anti-caking agent and leavening agent. It could also be used in wheat powder and gum ingredients.
7、Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from po***nous substances.
