    Abstract: A vitrified superabrasive product includes a superabrasive component and a vitrified bond component in which the superabrasive component is dispersed. The vitrified bond includes an oxide of a lanthanoid. Additionally, the vitrified bond component defines pores that can be essentially all less than 800 µm in diameter. Seventy percent of the pores are in a range of between about 40 µm and about 500 µm and have an average aspect ratio less than about 2. The porosity is in a range of between about 50% and about 90% of the total volume of the superabrasive product.

    Abstract: 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. 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. Features of the sealing component are as described above.

    Abstract: The invention relates to a method for manufacturing a flat strip of glass as a precursor of glass-ceramic, that comprises the continuous flotation of the molten glass on a molten metal melt in a flotation housing, said glass being poured at the molten state and at a temperature exceeding the devitrification starting temperature on the molten metal upstream from the housing, said glass progressively forming a running strip on said metal melt, the glass cooling speed being of at least 18°C/min between, on the one side, the moment when the glass is at the theoretical temperature of maximum devitrification rate and, on the other end, the following moment when the glass is at the theoretical temperature at which the devitrification crystal growth rate becomes lower than 1 micron per minute. The glass thus floated shows no devitrification.
