Set optical and application criteria before accepting a standard light PCC sample. This industrial light precipitated calcium carbonate is described as white superfine powder with formula CaCO3, stated purity 96% and a standard model choice.
Specify the result needed from optical testing
Explain whether numerical whiteness is a material acceptance requirement and request the corresponding measured result and method. White appearance and a chemical purity percentage describe different properties. Compare optical reports on the relevant test basis rather than using composition as an optical proxy.
Define the actual general-purpose application
Paint, plastic, rubber, paper making and building are named enquiry areas. Identify the particular formulation or process, its acceptance criteria and representative evaluation conditions. General-purpose wording does not qualify the powder for every system in those areas.
- Obtain current purity and impurity analysis for the proposed sample.
- Request particle-distribution or sieve measurements with their method.
- Clarify treatment, moisture or oil absorption where relevant to the application.
Keep the acceptance decision specific to the standard grade
Superfine does not establish numerical particle size, and light does not specify a density. Review the actual sample's observations against the agreed brief instead of inferring dispersion, coating properties, reinforcement or an addition ratio from the PCC name. Retain current technical and safety documents with the grade reference and evaluation record, and require relevant evidence before extending the conclusion to another use.
