Abstract
Abstract
In this paper, a spinning disk reactor (SDR) was applied and tested successfully for precipitated calcium particle synthesis. The proposed SDR reactor consists of a spinning disk rotating at 4,000–16,000 rpm. The proposed SDR resulted in high local supersaturation due to the intense energy dissipation produced by a high-speed spinning disk. The higher rotational speed of SDR results in the production of calcium carbonate nanoparticles with smaller mean particle sizes and higher aragonite content. At the rotating speed of 15,000 rpm, precipitated calcium carbonate nanoparticles with a size of around 975 nm were produced. In addition, aragonite content increased from 10 wt% to 95 wt% by increasing disk speed from 4,000 rpm to 15,000 rpm.
