Abstract
A glass-ceramic includes glass and crystalline phases, where the crystalline phase includes non-stoichiometric suboxides of titanium, forming ‘bronze’-type solid state defect structures in which vacancies are occupied with dopant cations.
Claims20
A glass-ceramic, comprising:
- an amorphous glass phase;
- and
- a crystalline phase comprising precipitates of a ternary metal oxide of formula M′xM″yOz, wherein M″ is a transition metal, y and z are such that M″yOz is a highest binary oxide of the transition metal, M′ is a dopant cation, and 0<x<1;
- wherein the transition metal is selected from the group consisting of W, Mo, V, and Ti;
- wherein the dopant cation is one or more selected from the group consisting of H, Li, Na, K, Rb, Cs, Ca, Sr, Ba, Zn, Ag, Au, Cu, Sn, Cd, In, Tl, Pb, Bi, Th, La, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu, U, V, Cr, Mn, Fe, Ni, Pd, Se, Ta, and Ce;
- and
- wherein the precipitates are distributed within amorphous glass of the amorphous glass phase of the glass-ceramic.
