| Abstract: | For the serious pressure from the three emergency subjects: environment, resources and sustaintionable development, it is necessary to develop some new kinds of substitutes for titanium white. As a potential raw material of high-grade white pigment, the advantage and disadvantage as well as process feasibility of the object of study, wollastonite, have been analyzed in this paper. The study of wollastonite surface procession showed that the sol-gel procession with self-made modifiers A, Z, S and M can raise its whiteness, and with modifier T can raise its index of refraction and its coveribility. |
