External appearance: white solid crystallize form

Specifications: 
1) Molecular formula: MgCl2
2) External appearance: white solid crystallize form
3) Content: 
    a) MgCl2: ≥99.9	
    b) K: ≤0.005	
    c) Na: ≤0.005
    d) Fe: ≤0.005
4) The surface of anhydrous magnesium lump is easy to damp end pollute, 
    thus the purity of magnesium chloride in the whole anhydrous magnesium 
    lump should be guaranteed by technique to be more then 98%
5) Use: the fire-proof material glues to match, antifreeze, prevent fire with 
    light burn the magnesium powder( MgO) synthesize the (MgO + MgCl) hard 
    cement, the magnesium cement, food, medicine trade
