This precipitated barium sulphate is an industrial white powder for the paint industry, with a minimum purity of 98.5%. Its 0.7 micron D50 and stated 98.5% whiteness provide separate fineness and appearance criteria for a buyer comparing blanc fixe ingredients.
Start with the paint raw-material requirement
The BaSO4 formula, CAS 7727-43-7 and blanc fixe name identify the offered sulfate powder. Define the intended paint binder and material acceptance limits before approving a substitute, since a common chemical name does not make every industrial sulfate grade interchangeable.
Interpret the 0.7 micron median correctly
The D50 of 0.7 microns describes the median of the particle distribution for this powder. Request the full measured distribution and method when the paint process needs control of upper particle sizes or a comparison with another grade; a median value alone does not describe every particle.
- Chemical acceptance
- The 98.5% minimum purity criterion should be checked against a current product-specific composition analysis.
- Appearance comparison
- The separate 98.5% whiteness criterion needs an agreed method and reference.
- Industrial classification
- The material is a white industrial powder intended for paint evaluation, not a finished paint system.
Qualify the powder in the chosen binder
Use current technical and safety documents together with a representative paint trial to judge the offered material. The fineness and whiteness criteria do not establish dispersion, hiding or gloss performance without the actual binder and test conditions, so set those acceptance tests for the complete formulation.
For this blanc fixe enquiry, keep the minimum assay, optical whiteness and 0.7 micron median as distinct requirements, then use the relevant paint trial to determine whether the proposed industrial powder meets the project.
