Transformation between Antase and Rutile Titania-Mica Pearlescent Pigment by MnO2 Induced Process

Article Preview

Abstract:

A chemical inducing process was developed to prepare titania-mica pearlescent pigment. MnO2 was used as crystal inducing promoters, a transformation between antase and rutile titania-mica pearlescent pigment was found by calcining at 800°C for 0.5 h. The mass ratio of mica to MnO2, pH value, temperature and dripping rate of MnO2solution and TiOSO4was studied. The crystalline form of titania-mica pearlescent pigment was measured by XRD.
