Industrial Lime & Limestone Insights

Read a calcium carbonate certificate of analysis line by line: CaO vs CaCO3, LOI, impurities, particle size, spec limits, red flags, and CoA vs TDS vs SDS.

Ground vs precipitated calcium carbonate: how GCC and PCC are made, how particle size, shape and purity differ, and which Indian standards and uses apply.

Calcium carbonate filler grades explained: mesh vs D50 and top cut, the spec lines that matter for PVC, paint and sealants, coating, and how to trial.

Calcium for poultry layers: why grit and powder do different jobs, which particle sizes and coarse-to-fine ratios to use, and what to check on a spec.
