Chemical and physical acceptance requirements should remain distinct in a barite enquiry. This industrial natural barium sulfate BaSO4 is described as white fine powder with stated BaSO4 ≥85.0%, for assessment in paint, ink, plastic, rubber and powder coating.
Set the chemical requirements for the offered grade
Request a current sample analysis and relevant impurity results. Keep the minimum BaSO4 content distinct from an exact composition. Confirm the proposed material's identification in matched technical, analysis and safety documentation so the reports describe the same grade.
Set the measured meaning of the physical grade
Obtain particle-distribution or sieve results with their method and material reference. Fine or superfine wording alone does not establish a numerical size or mesh fraction. White appearance is qualitative; a numerical whiteness requirement needs an appropriate optical report.
- Material evidence
- Link the chemical analysis and physical measurements to the offered powder.
- Acceptance brief
- Identify which results the actual formulation requires before trial assessment.
Qualify the grade within the intended system
Describe the paint, ink or compound and agree representative evaluation criteria. Request density and surface-treatment information separately where relevant. Assess other named uses independently rather than assuming equivalent behaviour between applications.
Retain the sample reference, conditions and observations with the report set. No verified dispersion, gloss, opacity, loading ratio or universal finished-formulation result is established by the natural-barite name, content minimum or superfine description alone.
