Particle size and a measured colour specification can focus a barite paint-filler enquiry while the chemical grade is confirmed. This powder has D50 at 8μm, pH 7±0.5 and an actual whiteness option of 98.5–99% for technical comparison.
Obtain one current chemical specification
Request the offered-grade BaSO4 assay and accepted chemical limits before approving the material. Review the oxide profile on its stated basis: CaO is 0.4%, Fe2O3 is 0.06% and SiO2 is 1%, with current methods and analysis still important to acceptance.
Separate the median from the crystal criterion
Use the explicit 8μm D50 when comparing the median requirement for the paint powder. Ask how the separate 50μm Largest Crystal criterion is defined and measured, rather than reading it as a particle percentile or a substitute for the full distribution.
- Colour comparison
- Confirm the method behind the actual whiteness range.
- Thermal measurement
- Request the unit and test conditions for loss on ignition.
Complete the paint trial documentation
Obtain treatment information and any applicable RoHS documents needed by the project. Evaluate the offered grade in the actual binder, with the coating's own dispersion and optical criteria determining acceptance.
Provide the chemical limits and intended paint system with the technical enquiry. A confirmed assay and a defined powder report make the comparison useful without an inferred density, compliance statement or finished-film guarantee.
