Use the formulation brief to decide which evidence must be compared for a barite enquiry. This industrial natural barium sulfate BaSO4 is described as white fine powder with stated BaSO4 ≥85.0%, for paint, ink, plastic, rubber and powder-coating assessment.
Choose the chemical criteria the reports must answer
Request a current sample analysis and relevant impurity results for the offered grade. The BaSO4 minimum is a threshold rather than an exact composition. Confirm the actual material's identification in matched technical, analysis and safety documents before using the results for selection.
Choose measured criteria for the physical grade
Ask for particle-distribution or sieve data, including the method and material reference. Fine or superfine wording does not define numerical size or a mesh fraction. If whiteness is an acceptance criterion, request an optical report; white appearance alone supplies no measured optical value.
Keep additional property questions explicit
Obtain density and surface-treatment evidence separately when those properties matter to the assessment. Neither follows from the natural-barite name or the minimum content.
Choose an evaluation suited to the actual system
Describe the paint, ink or compound and agree representative assessment conditions using the proposed powder. Qualify other named applications independently rather than assuming the same finished-product response. Retain the sample reference, criteria and observations with the report set. No verified dispersion, gloss, opacity or loading ratio is established by the chemical identity or superfine designation, and no universal formulation outcome is assured.
