Research on the Hydrothermal Processing of Mica-Titanium Pearlescent Pigment Precursor

Article Preview

Abstract:

This paper represents the study of hydrothermal processing of mica-titanium pearlescent pigment precursor. Mica-titanium pearlescent pigment precursor was prepared by boiling sulfuric acid hydrolysis method. Then the precursor was put into an autoclave and heated at 180°C~240°C for 4~12 hours. The results showed that the crystallinity of TiO2 increased with longer hydrothermal time and higher hydrothermal temperature. The morphology of mica-titanium pearlescent pigments which was prepared by high-temperature calcination and hydrothermal method was also studied.
