How Is Barite Powder Used?


According to different uses, the price difference of barite powder is relatively large, mainly for three major purposes.


1.Paint, zinc bismuth, ordinary glass and rubber filler:

Production of paint (BaSO4: 90 ~ 95%), barite powder filler can increase film thickness, strength and durability. Need less than 325 mesh, requiring high whiteness

Production of zinc antimony white (BaSO4: 95 to 98%) SiO2 <1%, the less the Al2O3, the better. The preparation of zinc-white barite requires a BaSO4 content of greater than 95% and should not contain visible colored impurities.

Ordinary glass (BaSO4: >96%) SiO2<1.5%, Al2O3<0.15%

The rubber filler (BaSO4: >98%) is less than 325 mesh and must not contain Mn, Cu or Pb impurities.


2.Chemical barite powder index

Project indicator percentage
Water soluble salt
Level  I
Level  II
Level  III

3.Oil drilling grade barite powder index (90% use)

Project indicator

Density, g/cm ≥ 4.2

Fineness, 200 mesh≥97%,325 mesh≥85~90%

Water soluble matter, ≤0.1%

Clay effect, Pa.s ≤ 0.125

Barium sulfate content, ≥90%


Subdivided, barite powder is also used in pesticides, steel surface quenching, phosphors, fluorescent lamps, fluxes, grease additives, etc.

Paving materials stress the buried pipelines in the marshes, replacing the lead plates for shielding of nuclear facilities, atomic energy plants, X-ray laboratories, etc., extending the life of the pavement

For anti-radiation mortar and concrete barite, the content of BaSO4 should be no less than 80%, and the impurities such as gypsum, pyrite, sulfide and sulfate should not exceed 7%.
