barium carbonate 99.2% min (CAS: 513-77-9)

Product name: Barium carbonate CAS NO.: 513-77-9 Molecular formula: BaCO3
Molecular Weight: 197.35 HS Code: 28366000 UN NO.: 1564 DG Class:6.1   Application:
Mainly used in magnetic materials, glass, ceramics, purify water, paints, pigments, paints, building materials and steel, carburizing, manufacturing other barium salts and reagents etc.   Product picture:   We produce both barium carbonate powder 99.2% and barium carbonate granular 99.2%, for powder, there are free flowing (also called heavy type) and precipitated (also called light type). The difference between free flowing and precipitated is the density.             Packing and container loading information:   Our normal package is of 25kg, 1000kg. We could also meet customer's special requirement for package specification.   For barium carbonate powder:        Specificatioin (please refer to below COA, according to Standard: GB1614-2002)
