Name; Barium chloride density : the relative density of 3.097 (24 ° C) traits : a colorless luster to the monoclinic crystal, toxic! dissolved : insoluble in water, soluble in almost hydrochloride. The ethanol lost crystal water but not dissolved. purposes : for tanning and manufacturing color amylin, pigments, etc., and for rodenticide poisoning and other hard water softener. preparation or sources : from barite and burning of coal and calcium chloride and prepared. Note : in the 113 ° C crystallization of lost water, air exposure can absorb moisture. categories : inorganic ITEM GRADE1 GRADE2 GRADE3 GRADE4 GRADE5 GRADE6 Bacl2.2H2O2 ≥104.00% ≥99.5% ≥99.00% ≥99.50% ≥99.00% ≥98.00% Calcium(Ca) ≤0.0010% ≤0.0030% ≤0.0050% ≤0.0320% ≤0.0360% ≤0.0650% SodiumNa ≤0.0003% ≤0.0005% ≤0.0010% ≤0.0020% ≤0.0025% ≤0.0030% Cacl2 ≤0.0030% ≤0.0090% ≤0.0150% ≤0.0900% ≤0.1000% ≤0.1800% Strontium(Sr) ≤0.0010% ≤0.0010% ≤0.0020% ≤0.0050% ≤0.0080% ≤0.0120% Sulphide(base on S) trace trace trace ≤0.0020% ≤0.0030% ≤0.0050% Fe ≤0.0002% ≤0.0003% ≤0.0007% ≤0.0005% ≤0.0007% ≤0.0010% Water insoluble ≤0.0030% ≤0.0040% ≤0.0250% ≤0.0080% ≤0.0080% ≤0.0100%
