A glass-ceramic seal for ionic transport devices such as solid oxide fuel cell stacks or oxygen transport membrane applications. Preferred embodiments of the present invention comprise glass-ceramic sealant material based on a Barium-Aluminum-Silica system, which exhibits a high enough coefficient of thermal expansion to closely match the overall CTE of a SOFC cell/stack (preferably from about 11 to 12.8 ppm/&#xb0; C.), good sintering behavior, and a very low residual glass phase (which contributes to the stability of the seal).

Sanbornite-based glass-ceramic seal for high-temperature applications

An abrasive article including a body having a bond material comprising an inorganic material, abrasive particles contained within the bond materials; and pores contained within the bond material defining a porosity of at least 90 vol % and not greater than 97 vol % for a total volume of the body.

Abrasive articles and method of forming same

An abrasive article including a bonded abrasive body having a bond material made of a vitrified material, abrasive particles comprising a first type of superabrasive material contained in the bond material, a porosity of at least about 50 vol % of the total volume of the bonded abrasive body, and a &#x394;CTE of not greater than about 5.5 ppm/&#xb0; C., wherein &#x394;CTE is defined as a difference between a CTE of the bond material and a CTE of the abrasive particles.

A cementitious composite material wherein glass-coated steel rods are positioned in a cementitious matrix. The glass composition for coating the steel reinforcing rods includes between about 33-45 weight percent SiO, 13.5-19.5 weight percent BO, 3.5-4.6 weight percent AlO, 4.0-13.5 weight percent KO, 5.5-15.5 weight percent ZrO, 8.6-15.9 weight percent NaO, 4.6-5.1 weight percent CaO, 0.6-0.7 weight percent MnO, 1.0-1.0 weight percent NiO, and 1.0-1.1 weight percent CoO. The glass composition is typically in compression on the rods at ambient temperatures, has a coefficient of thermal expansion of between about 12.5 and about 13.5, and has a softening temperature of between about 585 degrees Celsius and about 600 degrees Celsius.

Corrosion-resistant glasses for steel enamels

A substantially alkaline resistant calcium-iron-phosphate (CFP) glass and methods of making and using thereof. In one application, the CFP glass is drawn into a fiber and dispersed in cement to produce glass fiber reinforced concrete (GFRC) articles having the high compressive strength of concrete with the high impact, flexural and tensile strength associated with glass fibers.
