Jul 03, 2018· CaCO 3-TiO 2 composite particles were prepared with calcium carbonate (CaCO 3) and TiO 2 in stirred mill according the wet grinding method. The pigment properties, morphology, and structure of CaCO 3-TiO 2 composite particles and the interaction behaviors between CaCO 3 and TiO 2 particles were explored. In the CaCO 3-TiO 2 composite particles, TiO 2 is uniformly coated on the …
