Optimization of milling parameters on the synthesis of stearic acid coated CaCO3 nanoparticles--Deepika, S.
All samples were dried, weighed, crushed, split and milled prior to XRF analysis for major oxides, determination of LOI (100-1000 degrees C) and determination of CaCO3 and MgCO3 by back titration methods.
The coal briquettes used in this work were made by mixing the coal samples (Table 1) with Poly Vinyl Acetate (PVA) and CaCO3 in varying compositions.
It is a naturally occurring form of calcium carbonate, CaCO3.
When the drying CaCO3 carbonizes on the brick surface it creates insoluble CaCO3 that can be cleaned by pressed water or sand jet, only thus increasing the brick corrosion because the natural protection layer is getting damaged.
