size of 60 - 100 nm when examined by Scanning Electron Microscopy (SEM). The typical average particle size (d50) of food grade calcium carbonate is stated by industry to be about 5 µm, with an upper range (d98%) of 65 µm and less than 1% of particles having a diameter below 100 nm; the
Calcium carbonate (CaCO 3 ) is widely used in pharmaceutical industries and as a supplement in probiotics. The present study was designed to evaluate the effect of biofield energy treatment on the physicochemical properties of the CaCO 3 . The CaCO 3 powder was divided into two parts and referred as control and treated.
Also, hollow calcium carbonate has cavity inside. Repeating number controlled the wall thickness of hollow calcium carbonate. In the case of repeating number of 5, its wall thickness was about 1.3 μm. The average particle size of hollow calcium carbonate was adjusted from 7 to 18 μm by changing concentration of octane. The pore volume was ...
