A measured median can open a paint-powder comparison, while current chemical analysis determines the accepted grade. This industrial white barium sulphate barite powder has D50 at 8μm and pH 7±0.5 for that technical evaluation.
Confirm the assay before material approval
Request a current BaSO4 analysis and clearly agreed chemical limits for the powder being offered. A confirmed specification is the basis for deciding whether the candidate should move into a formulation trial, rather than relying on a broad high-purity description.
Use the median within a complete powder profile
Compare the explicit 8μm D50 with the intended paint requirement and ask for the full distribution. Obtain the measurement method and any surface treatment details before interpreting the median as a dispersion or finished-film advantage.
What should the optical report establish?
Request measured whiteness with its scale and test method for the offered grade. White appearance is descriptive, but it does not provide a quantified optical specification or determine the opacity and gloss of the finished paint.
Prepare the supporting test documents
Confirm the unit and conditions for loss on ignition, and obtain applicable RoHS documents if required. Agree the actual binder and the coating properties that will decide acceptance before evaluating the material in that system.
Include the chemical limits, particle requirement and paint brief in the enquiry. This keeps the selection grounded in documented grade properties and relevant formulation results without an inferred compliance or paint-performance guarantee.
