Composition and physical grading answer different questions when assessing barite for paint or ink. This industrial barium sulfate BaSO4 is described as white fine powder with stated BaSO4 ≥85.0%, with plastic, rubber and powder coating also named as material-evaluation targets.
Check the actual composition of the grade
The content minimum is an initial threshold rather than an exact analysis of every sample. Request current BaSO4 and relevant impurity results for the proposed material. Confirm its identification in matched technical, analysis and safety documents before making a grade comparison.
Give fineness and appearance measured definitions
White fine powder does not establish a mesh fraction, particle-distribution value or numerical whiteness. Ask for the actual grading and optical reports, including their methods and material reference. Request density or surface-treatment information separately if it matters to the intended formulation.
Keep the report set linked to the sample
Use the same grade reference across composition and physical data. This allows the material used in a formulation trial to be identified clearly in a subsequent enquiry.
Evaluate the grade in its intended formulation
Describe the paint or ink system and agree representative assessment criteria. Qualify any plastic, rubber or powder-coating role independently rather than transferring results between applications. Review current documentation and retain the actual conditions and observations. No verified dispersibility, gloss, opacity, loading ratio or universal finished-formulation result is established by the chemical name, minimum content or fine-powder description alone.
