Superfine Barium Sulfate

Molecular Formula: ,Molecular Weight: 233.40

 

Superfine Barium Sulfate speciality: HYBS-L barium sulphate is produced in advanced chemical precipitation method, good physical properties, low technical impurity, even fineness; white powder or paste, non-toxic ,insoluble in water, soluble in fuming sulphuric acid, stable chemical property; can absorb X-ray, and endow the material with high density and surface finish.

Applications and Usages: mainly uses in the powder paint, the water paint, printing ink, plastic, rubber, papermaking, medicine synthesis chemical industry, ceramics, cosmetics etc.

Superfine Barium Sulfate examination method:

1,grain-size distribution: determination by GSL-101B I laser pellet distributed measuring apparatus.

2,even diameter particle size: Obtains the particle size intermediate quantity by the grain-size distribution.

3,BET Surface: Transforms by the average grain diameter, the unit is the 1g powder relative area.

4,325MESH remnant remainder: Puts the 1000g test specimen in 325mesh filters by the aqueous method ,calculates its residual proportion.

5,Postulate specific gravity: Puts the 50g test specimen in 100C.C graduated cylinder which has the scale division, highly falls from 5cm to floor about 150 times,then measure the definite value.

6,whiteness: measure by the Shanghai SBDY-1 whiteness apparatus.

7,moisture content: JLS-K5101 110 °C 2 hours.

8,PH value: measured by PHS-3C precise PH apparatus.

9,Absorbed Oil value: Use method of the JLS-K5101, joins the linseed oil then titrate, determines when becomes massive.
