Here we discuss the method of preparation of golden pearl pigment by ferric oxide's wrapping on titanium-mica,and also we research the quatity of ferric oxide,temperature,pH which in- fluence the quality of product.

Here we discuss the preparation method of green pearl pigment by de- positing chromium oxide on the micatitanium,and research the wrap- ping quantity of chromium,reaction tempture,calcining tempture,and so on which affect the quality of product.
