Preparation of CaCO3-TiO2 Composite Particles and
CaCO3-TiO2 composite particles were prepared with CaCO3 and TiO2 in stirred mill by wet grinding. Firstly, the CaCO3 slurry and TiO2 slurry were prepared. CaCO3 and TiO2 were respectively mixed with water and sodium polyacrylate (dispersant) according to a certain proportion and stirred by a high-speed dispersion machine.During this process, wet or dry milling condition is adopted. The decreasing of particles size depends on the powder-to-ball weight ratio. Fig.1. Commercial Ball Mill image. Figure is adapted from [11]. Ball mill image is shown in Fig.1.
