to 1 M sucrose solution (50.0 mL) to produce calcium sucrate. Stearic acid (0.284 g dissolved in 10.0 mL of absolute ethanol) was added to the calcium sucrate solution, while stirring. Carbon dioxide gas was bubbled, through the mixture of calcium sucrate and stearic acid, to synthesize stearic acid-coated calcium carbonate nanoparticles.

NETZSCH Ecutec Coating Systems utilize a Sierra Pin Mill with high shear forces to achieve the best de-agglomerating action. Simultaneously CaCO3 and stearic Acid are added into a highly turbulent area which is the key to a perfectly coated product with a very low consumption of stearic acid (0.5% and 1%, depending on product fineness).

Problem: Calcium Carbonate is a commonly used filler in plastics compounding.Typically, a stearate coating is required to improve dispersiblity of this additive into the compounding process. Traditional coating processes can form undesirable agglomerates that increase the amount of additive required. Due to the high costs of stearates, companies looked for an effective, continuous coating ...

A method for treating calcium carbonate includes combining calcium carbonate with an amount of stearic acid and an amount of water to form a mixture, the amount of water being at least about 0.1% by weight relative to the total weight. The method further includes blending the mixture to form a stearic acid-treated calcium carbonate composition.

Mar 24, 2010· A series of experimental precipitated calcium carbonates (PCCs) coated with commercial stearic acid (stearin), with the coating amount of stearin added to the PCC particles ranging from 3 to 13.5 wt %, were prepared in aqueous medium and characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC).
