A BaSO4 content minimum does not by itself define every aspect of a barite grade. This industrial natural barium sulfate is described as white fine powder with stated BaSO4 ≥85.0%, for paint, ink, plastic, rubber and powder-coating enquiries.
Ask for composition beyond the minimum
Request a current analysis of the actual offered material and the relevant impurity results. Keep the content threshold distinct from the exact sample analysis. Confirm the material's identification in matched technical, analysis and safety documents before comparing proposed grades.
Ask how the superfine designation is measured
Obtain particle-distribution or sieve results with their method and material reference. Fine or superfine wording does not establish a numerical particle value or a specific mesh fraction. Agree the grading limits required by the intended formulation.
Define optical acceptance separately
White appearance is qualitative. Request the relevant optical report and test method if numerical whiteness matters. Obtain density and surface-treatment information independently where those properties affect the material assessment.
Evaluate the actual grade in the proposed system
Describe the formulation and agree representative assessment criteria for the intended paint, ink or compound. Qualify other named applications separately rather than assuming the same result will transfer between systems. Retain the sample identity with the report set, conditions and observations. No verified dispersion, gloss, opacity, loading ratio or universal finished-formulation performance is established by the minimum content, natural-barite name or superfine description alone.
