For an industrial powder-coating enquiry, this natural-barium-sulfate barite powder provides an 8 micron D50 criterion. Confirm the actual assay and offered optical grade before assessing the mineral against the proposed binder and processing requirements.
Define the natural powder grade for the binder
Request current composition and impurity analysis, with confirmation of the actual natural-material route. The whiteness offering spans 75–92%, so agree the proposed grade and optical reference rather than treating the full range as a single committed colour specification.
Build the particle comparison around D50
The 8 micron median needs a confirmed measurement method and, where relevant, the actual distribution curve for the powder-coating process. Keep the largest-crystal description separate from that distribution and avoid inferring a complete powder-size limit from either entry.
- Mineral constituents
- CaO is 0.4%, Fe2O3 is 0.06% and SiO2 is 1%, with the actual grade analysis to be confirmed.
- pH comparison
- Use the 7±0.5 range with a defined preparation and test procedure.
- Supporting documents
- Obtain current product-specific technical and safety information, plus applicable RoHS evidence where required by the project.
Judge acceptance in the actual powder-coating system
Define the sulfate's proposed role and the process and finish tests needed to approve the formulation. A paint application direction or mineral identity does not establish dispersion, film appearance or compatibility in every binder, and a coating-material enquiry should use representative system results.
For this natural barite, connect the confirmed chemical assay and chosen whiteness grade to the measured powder criteria before approving a comparison. The actual binder trial can then establish whether the proposed material meets the project's industrial powder-coating requirements.
