SYNTHESIS OF CALCIUM CARBONATE NANOPARTICLES BY NEW RECYCLE REACTOR USING CAVITATION TECHNIQUE.

摘要

The use of nano sized calcium carbonate as a filler material in polymer composites, paints, coatings, has gained substantial importance due to its value addition in terms of properties and reduction in cost of the final product. This work reports a reactor design for based on the principle of hydrodynamic cavitation for bulk synthesis of the calcium carbonate nano-particles. The bubbling of the CO2, gas in the cavitation zone leads to faster gas absorption rates and hence enhances the rate of reaction. This work gives the details of the design, and minutes about variation of compostion and design of orifice plates.
