Patent number: 8354202Abstract: A fuel cell includes a ceramic component and a sealing component. The sealing component includes a first glass-ceramic layer over the ceramic component and a second glass-ceramic layer over the first glass-ceramic layer, each of the first and the second glass-ceramic layers independently including between about 0.5% and about 50% glass phase content by volume. The first glass-ceramic layer includes a higher glass phase content than the second glass-ceramic layer, and between about 0.5% and about 10% glass stabilizer component by weight.Type: GrantFiled: December 16, 2008Date of Patent: January 15, 2013Assignee: Saint-Gobain Ceramics & Plastics, Inc.Inventors: Gilles Querel, Shailendra S. Parihar, George K. Parker, Patrick Garnier

The sealing component includes a first glass-ceramic layer over the ceramic component and a second glass-ceramic layer over the first glass-ceramic layer, each of the first and the second glass-ceramic layers independently including between about 0.5% and about 50% glass phase content by volume. The first glass-ceramic layer includes a higher glass phase content than the second glass-ceramic layer, and between about 0.5% and about 10% glass stabilizer component by weight. In a method of sealing a ceramic component of a fuel cell, a first coat is applied over a first ceramic component of the fuel cell, the first coat including SiO2, and further including between about 0.5% and about 10% glass stabilizer component by weight. A second coat is applied over the first coat, the second coat including SiO2. The first and second coats are heated to form a sealing component, to thereby seal the ceramic component with the sealing component.Type: ApplicationFiled: December 16, 2008Publication date: August 6, 2009Applicant: Saint-Gobain Cermics & Plastics, Inc.Inventors: Gilles Querel, Shailendra S.

Patent number: 4904293Abstract: Production of microspheres having a very high silica content produced from a starting glass whose silica content is less than 80% by weight, with the remainder being essentially made up of boron oxide and one or more alkaline oxide(s). This starting glass is reduced into fine particles by grinding, optionally mixed with a fluidizing agent, and then passed through the flame of a burner at a temperature at least equal to 1500.degree. C. to form molten hollow microspheres which are suddenly cooled to form solid hollow microspheres. The microspheres produced thereby are recovered and contacted with a dealkalization agent to increase the silica content thereof to at least 92%.Type: GrantFiled: August 2, 1988Date of Patent: February 27, 1990Assignee: Saint Gobain VitrageInventors: Patrick Garnier, Daniel Abriou, Benoit Beghin

Patent number: 4661137Abstract: The invention relates to a process and apparatus for producing hollow glass microspheres. According to embodiments of the invention, particles of a soda-lime-silica glass containing slight amounts of sulfur compounds are suspended in a gaseous current and expanded in a burner, at a treatment temperature at least 100.degree. C. above the working temperature at which the specific type of glass constituting the treated particles is made from its raw materials, such as sand, lime, sodium carbonate, sodium sulfate, and others, depending on the particular type of glass. The process makes it possible to increase the yield of the transformation of the particles.Type: GrantFiled: June 20, 1985Date of Patent: April 28, 1987Assignee: Saint Gobain VitrageInventors: Patrick Garnier, Daniel Abriou, Michel Coquillon
