Supplementary Notes
1. Nano calcium carbonate: particle size 10–100 nm (0.01–0.1 μm), not marked by mesh size, equivalent mesh size >12500.
2. The data in the table is the standard reference value of median diameter D50; actual powder has a particle size distribution range depending on manufacturers.
3. Heavy calcium carbonate & light calcium carbonate share the same mesh-particle size standard, differing only in oil absorption value and whiteness.
