Barite BaSO4 Material for Paint Evaluation, 80–97% Content and 1% Maximum Moisture

A paint raw-material enquiry for this barite should first define the supplied form and the preparation the project requires. The chemical criteria include 80–97% BaSO4 content, a maximum moisture content of 1% and a CaO entry of 0.5%.

Clarify the barite form for the paint process

Confirm whether the offered material meets the project's powder or mineral-feed requirement, together with its actual dimensions and preparation specification. A paint formulation needs a defined usable particle distribution; a raw-material dimension or crystal-size entry should not be treated as that distribution.

Choose the actual assay and colour grade

The BaSO4 range of 80–97% and whiteness range of 75–92% need a specific offered-grade commitment before meaningful comparison. Obtain a current mineral and impurity analysis, agree the optical method and reference, and assess the proposed grade against the intended paint rather than assuming every material within those ranges is equivalent.

Moisture acceptance

Use the maximum 1% criterion with a defined test method and representative analysis.

Composition review

Confirm CaO and other constituents relevant to the project rather than interpreting an unspecified iron value as zero.

Physical preparation

Request the delivered form and measured powder criteria needed for the actual processing route.

Assess the prepared mineral in its intended matrix

Coating, plastic and rubber are also identified directions, each requiring its own material preparation and formulation assessment. For the paint enquiry, define the binder, finish and process acceptance tests, with current product-specific safety information before sample approval.

Let the confirmed delivered form, chosen assay and measured colour criteria establish a precise trial brief. The representative paint comparison can then determine whether the proposed barite meets the project's actual raw-material needs.
