Keep composition, physical grading and formulation qualification as separate parts of a barite decision. 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 enquiries.
What confirms the chemical grade?
Request current BaSO4 and relevant impurity results for the actual sample. The content minimum is an initial threshold rather than its exact composition. Confirm the offered material's identification in matched technical, analysis and safety documentation.
What confirms the physical grade?
Obtain particle-distribution or sieve measurements and their method. Fine or superfine wording does not establish a numerical particle value or mesh fraction. White appearance is qualitative, so an optical report is required when numerical whiteness matters to the acceptance brief.
- Link the chemical analysis and physical reports to the same grade.
- Agree the measurements required by the intended formulation.
- Request density and surface-treatment evidence separately where relevant.
What confirms suitability in the actual system?
Describe the paint, ink or compound and agree a representative evaluation using the proposed powder. Assess the other named applications independently rather than assuming the same result transfers between systems.
Keep the sample identity, conditions and observations with the linked report set for later material enquiries. No verified dispersion, gloss, opacity, loading ratio or universal finished-formulation performance is established by the natural-barite name, minimum BaSO4 content or superfine designation alone.
