Which grade will be used for the application assessment? This industrial precipitated light calcium carbonate is described as white superfine powder with formula CaCO3 and stated purity 96%; identifying the proposed sample is the first useful enquiry step.
Identify the option and request its evidence
The model choices are premium product and standard product. Ask for current technical and analysis reports tied to the choice being proposed, including the actual measured differences between them. A name does not establish a higher purity or a performance hierarchy.
Define the physical acceptance questions
Request a particle-size distribution or sieve result with the method and relevant metric. Superfine does not supply a numerical grading, and light is not a density specification.
Check composition and other required tests
Confirm the stated purity and relevant impurity results in the current analysis. Obtain numerical whiteness, moisture, oil absorption or surface-treatment evidence when those properties form part of the application brief.
Judge the candidate in the intended use
Paint, plastic, rubber, paper making and building are the named areas for assessment. Describe the actual formulation or process, establish representative evaluation conditions and compare observations against its acceptance criteria. Chemical identity alone does not verify dispersion, coating performance, reinforcement, paper properties or an addition ratio. Keep the grade reference with current technical and safety documents, and require relevant evidence for each additional use rather than assuming the same result transfers between systems.
