A minimum assay and a measured median give an industrial filler enquiry a clearer starting point. This white barium sulphate powder has 90% minimum purity and an 8.8μm D50 for paint, powder-coating and polymer evaluation, with the intended formulation guiding the remaining qualification questions.
Define the 90% minimum material brief
Use the BaSO4 identity and minimum assay to establish the chemical requirement for the comparison. Confirm the offered mineral or production route before specifying it, because a purchasing brief should identify the actual material rather than assume how every barium sulphate powder is produced.
Connect the median to the formulation
The 8.8μm D50 is one point in the particle distribution, not a complete description of the powder. Request the remaining distribution, measurement method and treatment information, then compare the grade under the paint or engineering-plastic conditions that matter to the project.
- Paint and powder coating
- Define binder, finish and the trial measurements needed for acceptance.
- Polymer and rubber
- Confirm the receiving matrix and its material qualification requirements.
Keep separate uses separately qualified
The 88% whiteness and pH range of 6.5–9 provide further powder comparison values. They do not establish a food approval or an oil-drilling result, so those requirements need their own applicable documents and tests before selection.
Build the enquiry around the 90% minimum BaSO4 powder and a clearly identified application. A confirmed route and a relevant formulation trial will make the final filler choice more defensible than a broad grade label alone.
