Properties:
white weight super-fine powder. Density 4.50g/cm3; melting point:
15800C. tasteless, innoxious. Dissolve in hot oil of vitriol, not
dissolve in water, ethanol and diluent acid. Vulnerable to agglomeration
dried. It becomes poisonous if containing soluble barium compound.
Application: Mainly used for
stuffing and increasing weight in paint, printing ink, ad paint,
cosmetics and PVC; for stuffing and strengthening of rubber products;
for clarifying, de-froth and polishing of glass products; material for
manufacturing leather and other barium chloride including barium
chloride, barium hydroxide etc; for making printing paint of
manufacturing wooden grain printing board in wooden material industry;
for stuffing green paint and color deposit material; mixed with magnetic
soil in copper board test paper in paper making industry; for painting
cloth when mixed with dye solution in was paper production; for making
shadow in X ray in medical treatment; as expansion of cathode board in
electronanalysis. In addition, it is also used in producing ceramics, ,
photo paper, artificial ivory, analysis chemical reagent etc.; measuring
azote content in drought crops and soil. |

Properties:
white crystal. Piece solid, orange or yellow; bitter taste, poisonous;
dissolve in water, aether; stable solution. Decompose sulfureted hydrogen
after heated. Produce sodium carbonate and sulfureted hydrogen acting with
carbon dioxide in the air. When mixed with air, sulfureted hydrogen becomes
explosive. Produce hyposulphite after oxidation in the air.
Application: Applied to tannage and depilation in leather making
industry; applied to getting rid of sulfur in desulfurizer of active carbon;
applied to dyeing of sulfurous acid in artificial fiber industry; applied to
mine selection in copper mine; Auxiliary for producing sulfuration dye;
material for producing sulfuration ammonium and ethanethiol semi-finished
products; as well as producing medical medium and chemical organic silicon
series. |

Properties:
white crystal. Cold crystal takes the shape of flat diamond , hot
crystal takes the shape of amorphism. Density: 3.917g/cm3 melting point:
9630C; boiling point: 15600C. It normally contains two crystal water
which is stable in the air and not vulnerable to effloresce, but
transformed to white powder when heated to 1130C. Vulnerable to dissolve
in water and ethanol and acid. The water solution tastes bitter and tiny
cool. Produce barium carbonate when worked with carbonate; produce white
barium carbonate worked with sulfate.
Application:
Chemical material of widest application in barium chloride. Applied to
manufacturing all kinds of barium chloride in chemical industry; applied
to steel heat treatment , quenching of alloy steel cutting tools ; and
replace sodium cyanide as the cementite solution in steel industry. In
addition, it is found in boiler treatment and salt electroanalysis;
anti-fading of ceramics; manufacture of tannage, light sensitive
materials, pesticide and artificial silk digestant. |
