This industrial precipitated barium sulphate white powder has a minimum purity requirement of 98% and a BaSO4 purity value of 98.6%. For a paint or coating comparison, confirm the actual offered assay and relevant powder criteria before assessing the proposed material.
Agree chemical and optical acceptance independently
The 98.6% BaSO4 value and 98% whiteness describe different criteria. Request a current composition and impurity analysis and an agreed optical method and reference, so the paint comparison does not treat chemical purity as a measured finished-film result.
Define what a narrow-particle enquiry requires
Obtain the actual D97 unit, measured distribution and method before comparing powder fineness. A narrow-particle description does not establish a distribution width by itself, while the 0.01% residue on a 325 mesh sieve needs its own procedure rather than being converted into a median size.
- Moisture criterion
- Use the 0.07% value with an agreed conditioning and measurement method.
- pH criterion
- The 6.5–9 range needs a defined preparation and test basis.
- Grade documentation
- Confirm the offered precipitated material, composition and product-specific safety information, plus any required applicable certificate scope.
Approve the actual powder in its intended binder
Identify the paint or coating binder, sulfate role and process and finish requirements for the representative trial. A white appearance and precipitation description do not establish hiding, compatibility or a finished-coating advantage across every system.
For this sulfate enquiry, let the confirmed assay, optical method and measured powder specification define the grade comparison. The actual formulation results and relevant current documents should determine whether the proposed material meets the project's processing and appearance requirements.
