Glass-ceramics were produced by impregnation of powders onto a surface under pressure. Samples of four classes of oxide powders (SnO(2), Co(3)O(4), TiO(2) and Al(2)O(3)) were infiltrated into a commercial float glass substrate. These powders were impregnated on the glass surface under high gas pressure (16-18 atm) and below the T(g) temperature in a specially designed pressurized chamber to form M(x)O(y)-SiO(2) films. The phases were analyzed by X-ray diffraction (XRD), and the results reveal the structure and crystallinity of the selected oxide powders as prepared and after inclusion in the glass substrate. The formation of films by the proposed method is viable due to the mean particle size of the powders deposited on the glass surface. Differences in the surface morphology of glass-ceramics films were attributed to the morphology of the powders used for impregnation. The formation mechanism of M(x)O(y)-SiO(2) films was based on compositional differences in the glass substrate before and after the powder impregnation process and on their surface morphology.
