Industrial White Barite Lump for Paint and Coating Evaluation, 80% BaSO4 Content and 0.3% Moisture

This industrial white barite is identified in lump form, with 80% BaSO4 content and 0.3% moisture. For paint or coating development, define the mineral preparation required before comparing the material with a formulation-ready powder.

Plan the lump-to-formulation material specification

Lump is the stated physical form rather than a measured pigment-size distribution. Confirm the delivered dimensions and any required preparation, then obtain the actual powder-size criteria needed by the intended paint process instead of treating a mineral lump as an interchangeable coating ingredient.

Confirm the offered whiteness and composition

Agree the whiteness criterion for the actual grade and the optical method used to measure it. The 80% BaSO4 content is a separate chemical criterion, so request a current mineral and impurity analysis rather than interpreting white colour as a purity or finished-film performance guarantee.

Mineral constituents

CaO, Fe2O3, MgO, BaO and Na2O each have a 1% entry, while SiO2 is 2%; confirm their analytical basis for the offered material.

Moisture criterion

Compare the 0.3% value using an agreed test method and representative sample.

Certificate requirements

Obtain current applicable ISO or REACH documentation with the relevant scope if the project requires it.

Approve the prepared barite through the coating trial

A representative paint or coating formulation should establish whether the prepared mineral meets the actual processing and appearance requirements. The industrial grade and barite name do not determine hiding, dispersion or compatibility across every binder, and the intended role should be explicit before a sample is approved.

For this lump enquiry, agree the supplied form, composition, whiteness grade and preparation criteria together. Those commitments create a meaningful basis for assessing the resulting material in the chosen coating system.
