Annealing treatments for modified titania-silica glasses and the glasses produced by the annealing treatments. The annealing treatments include an isothermal hold that facilitates equalization of non-uniformities in fictive temperature caused by non-uniformities in modifier concentration in the glasses. The annealing treatments may also include heating the glass to a higher temperature following the isothermal hold and holding the glass at that temperature for several hours. Glasses produced by the annealing treatments exhibit high spatial uniformity of CTE, CTE slope, and fictive temperature, including in the presence of a spatially non-uniform concentration of modifier.

The present invention provides additive manufacturing compositions, also referred as inks in the field of additive manufacturing, which can be fine-tuned with respect to porosity by varying the intensity of the photopolymerisation light source and which can further be used to obtain objects out of glasses, ceramics or glass-ceramics and their respective alloys.

Disclosed is a method of manufacturing a crystallized glass for a secondary battery. The secondary battery include a solid electrolyte comprising sulfide, which can be prepared by synthesizing sulfides using thermal energy and vapor pressure as energy sources. The method of the present invention is suitable for manufacturing a crystallized glass for use as the electrolyte comprising sulfide of the secondary battery. The method includes dispersing two or more kinds of sulfides in a solvent and synthesizing the sulfides under conditions of a temperature equal to or greater than a boiling point of the solvent and high pressure greater than standard atmospheric pressure.

Provided herein are methods for preparing nano-macroporous glass articles, such as bioscaffolds, from starting materials such as phosphosilicate glasses made by melt-quench methods, mixed with a soluble pore former such as a sugar, followed by steps of dissolving, heating, and leaching to yield a glass composition having a highly interconnected system of both macropores and large scale nanoporosity.

Ultralow expansion titania-silica glass. The glass has high hydroxyl content and optionally include one or more dopants. Representative optional dopants include boron, alkali elements, alkaline earth elements or metals such as Nb, Ta, Al, Mn, Sn Cu and Sn. The glass is prepared by a process that includes steam consolidation to increase the hydroxyl content. The high hydroxyl content or combination of dopant(s) and high hydroxyl content lowers the fictive temperature of the glass to provide a glass having a very low coefficient of thermal expansion (CTE), low fictive temperature (T.sub.f), and low expansivity slope.
