This invention provides a modified fluorophlogopite powder and its preparation method, as well as a silvery-white mica titanium pearlescent pigment and its preparation method and applications, relating to the field of inorganic pigment technology. The preparation method of the modified fluorophlogopite powder provided by this invention includes the following steps: sequentially subjecting the fluorophlogopite powder to calcination activation, alkali activation, acid activation, water washing, and drying to obtain the modified fluorophlogopite powder. This invention also provides a silvery-white mica titanium pearlescent pigment, comprising the modified fluorophlogopite powder and a rutile titanium dioxide layer coating the modified fluorophlogopite powder. This invention uses the modified fluorophlogopite powder as a substrate and coats its surface with a rutile titanium dioxide layer, forming a silvery-white mica titanium pearlescent pigment with excellent high-temperature stability. It can maintain the integrity of its layered structure and the optical stability of the coating layer above 1000℃, showing great application potential in high-temperature fields such as ceramics.
