A yellow pearlescent pigment has been prepared based on the technology of coating the BiVO4 on the titania-mica pearlescent pigment.

For thesake of knowing mechanism of preparing nacreouspigment of mica titanium and adjusting pH with urea, we need to measure fast and exactly concentration of titanium to direct preparing top grade nacreous pigment of mica titanium.

TiO2 - mica nacreous pigment with Fe2O3 is prepared by the process of boiling hydrolysis.

Study on the technology of basic lead carbonate pearlescent pigment by pushing process and inversing phase method;

The current study on improving the characteristics of mica pearlescent pigment using the surface modification;

New progress and preparation methods for pearlescent pigment;

The pearly pigment of mica titanium was prepared by using the liquid deposition method with the urea as precipitant.

Changzhou Research Institute of Coating Chemical Industry developed new technologies including purification and sizing, mica activation, controlled hydrolysis and coating process of titanium tetrachloride and continuous calcinations resulting in high quality series mica - base pearly pigments on facilities with a capacity of 100 t/a.
