Key Indicators and Applications of Superfine Calcium Carbonate

The average primary particle size of superfine calcium carbonate should be 0.02–0.1 μm. This is a basic requirement. Otherwise, it cannot be called “ultrafine.” However, this is only half the task. If surface treatment and dispersion technology are insufficient, the primary particles will agglomerate into secondary particles hundreds of nanometers in diameter. Transmission electron microscopy […]
