Production and Characterization of Nano-Caco3 From Clamshell (Geloina Sp.) by Top-Down Method

Abstract

The utilization of nano-CaCO3 is currently growing very fast in various fields. The research aims to produce and analyze the properties of nano-CaCO3 from clamshells (Geloina sp.). The production of nan-CaCO3 was done by the top-down process using high-energy milling. The clamshell (Geloina sp.) is the potential resource of nano-CaCO3. The nano-CaCO3 can be produced by the milling process. The main factor that affected the yield is the number of steel balls, while the speed of rotation and number of cycles have a negative effect. The EDX analysis shows that the nano-CaCO3 has high purity. The nano-CaCO3 from clamshell (Geloine sp.) can be applicated as a drug delivery system and catalyst.
