Fabrication of anatase precipitated glass-ceramics possessing high transparency

Transparent anatase precipitated glass-ceramics were fabricated using ZnO as a component. The particle size of precipitated anatase is several nanometers enough to possess high transparency. The preparation of the Bi-free transparent TiO(2) glass-ceramic was attained by substitution of two different kinds of oxides for bismuth oxide. It is also noteworthy that we have demonstrated the crystallization of metastable anatase in the glass-ceramics as a main phase. The present bulk anatase glass-ceramics will open up an application field for a TiO(2)-containing photocatalyst.
