A wollastonite mineral enquiry can start with the actual mesh model and the measurements needed by the formulation. This powder carries an acicular designation and has two actual model options, 800mesh and 1250mesh, with stated oxide and whiteness values.
Compare the oxide limits for the selected mesh model
The listed Fe2O3 content is ≤1.2%, while SiO2 content is 48%–51%. Request current analysis with the test methods and confirm that it identifies the offered model, so chemical comparisons concern the material actually being evaluated.
Ask how the whiteness value was measured
The stated whiteness is ≥92%, without a defined test method or scale. Obtain that measurement basis before comparing optical values across materials, and identify which optical acceptance requirement matters to the intended formulation.
- Model identification
- Actual 800mesh or 1250mesh option linked to its analytical report.
- Morphology evidence
- Relevant particle-distribution and shape measurements, with an aspect-ratio basis where the project requires it.
Assess the acicular designation through actual morphology data
An acicular name does not by itself supply measured particle geometry or a reinforcement result. Request the morphology evidence needed by the project, and avoid converting the mesh label into an assumed D50 or D97 value.
Describe the actual material duty and compare a suitable sample against the formulation criteria. Review current safety information alongside the oxide, optical and particle reports, keeping the chosen mesh model with the relevant test observations before deciding whether this wollastonite meets the intended requirements.
