| Abstract: | Superfine TiO_2 powders were obtained by a hydrolysisgel method. The composementand structure as well as its transformation of the titania gels were studied, then the size and specificsurface area were also determined by means of DTA, XRD, TEM, BET ets. It was found that thehigh pure and monosized spheroidal TiO_2 superfine powder could been prepared by the hydrolysis-gelmethod, and it had high surface areas and excellent sintering property. |
