摘要： Methods for chemically strengthening glass articles, e.g., glass sheets, are disclosed, in which computer-implemented techniques are employed to select the conditions, e.g., times, temperatures, and bath compositions and sizes, used in the chemical strengthening. The computer-implemented techniques can be applied to chemical-strengthening methods that employ more than one ion-diffusion treatment, e.g., more than one ion-exchange treatment or a combination of at least one ion-exchange treatment and at least one heat treatment. Through the use of the computer-implemented techniques, more precisely-controlled ion concentration profiles can be achieved in chemically-strengthened glass articles, which can improve the ultimate mechanical properties of the articles.

摘要： Disclosed herein are glass-ceramics having crystalline phases including β-spodumene ss and either (i) pseudobrookite or (ii) vanadium or vanadium containing compounds so as to be colored and opaque glass-ceramics having coordinates, determined from total reflectance—specular included—measurements, in the CIELAB color space of the following ranges: L*=from about 20 to about 45; a*=from about −2 to about +2; and b*=from about −12 to about +1. Such CIELAB color space coordinates can be substantially uniform throughout the glass-ceramics. In each of the proceeding, β-quartz ss can be substantially absent from the crystalline phases. If present, β-quartz ss can be less than about 20 wt % or, alternatively, less than about 15 wt % of the crystalline phases. Also Further crystalline phases might include spinel ss (e.g., hercynite and/or gahnite-hercynite ss), rutile, magnesium zinc phosphate, or spinel ss (e.g., hercynite and/or gahnite-hercynite ss) and rutile.

摘要： Doped and partially-reduced oxide (e.g., SrTiO3-based) thermoelectric materials. The thermoelectric materials can be single-doped or multi-doped (e.g., co-doped) and display a thermoelectric figure of merit (ZT) of 0.2 or higher at 1050K. Methods of forming the thermoelectric materials involve combining and reacting suitable raw materials and heating them in a graphite environment to at least partially reduce the resulting oxide. Optionally, a reducing agent such as titanium carbide, titanium nitride, or titanium boride can be incorporated into the starting materials prior to the reducing step in graphite. The reaction product can be sintered to form a dense thermoelectric material.
