Product Description

General Characteristics:

Formula:                       MgCO3; 4MgCO3·Mg (OH) 2·5H2O; MgCO3·5H2O

Appearance:                 White powder

Molecular weight:        84.31; 485.65; 102.33;

Odor:                            Odorless                   

CAS Number:              546-93-0; 39409-82-0; 23389-33-5

EINECS No.:                208-915-9                 

INS:                               504(i)                       

Solubility:                     It is practically insoluble in water,to which, however, it imparts a slightly alkaline reaction. It is insoluble in alcohol, but dissolves, with effervescence, in dilute acids.

Uses:

· PH regulator agent

· Drying agent

· Color-retention agent

· Anti-caking agent

Packing and Storage:

· 25kg/net paper bag and PE bags sealed inside.                                

· Store in a well-closed bag at room temperature, protect from light, moisture and pest infestation.              

· Shelf life---two years
