    摘要： A composite sealant for in-situ sealing a fuel cell stack is provided. A paste of the sealant mixture is initially formed by mixing a glass precursor powder and a reacting filler material. The sealant mixture paste is applied to selected sealing locations of the fuel cell stack. The sealant mixture paste is then transformed into a composite sealant material to seal the selected sealing locations by heat treatment in air to about 900° C. The composite sealant material comprises a glass matrix phase and a reinforcing phase including a plurality of interlocked elongated single crystal grains. The reacting fillers modify the CTE and significantly improve the gap filling capacity of the composite sealant material and provide superior pressure containment capability at elevated temperatures.

    摘要： A method for making a glass frit paste is provided. First, nitrocellulose is dissolved in a high vapor pressure solvent of the nitrocellulose to make a solution. A portion of the solution is then mixed with alpha-terpineol to form a vehicle. Glass frit is mixed with the vehicle and then ground to form the paste. During the grinding step most of the high vapor pressure solvent evaporates. The resulting paste has a composition comprising about 0.3-12.0 wt. % nitrocellulose, about 0.5-2.0 wt. % of a high vapor pressure solvent of said nitrocellulose, about 14.0-25.0 wt. % alpha-terpineol, and the remainder glass frit.

    摘要： A dry pressing and slip casting process is provided for the manufacture of glass-ceramic components of the type used in sensors. Both process on starts with a powder composition of SiO2 (42-59 wt. %), Al2O3 (17-35 wt. %), MgO (2-25 wt. %) and also BaO (0-20 wt. %), TiO2 (0-12 wt. %), ZnO (0-10 wt. %), CaO (0-10 wt. %), B2O3 (0-5 wt %), P2O5 (0-5 wt. %), ZrO2 (0-5 wt. %), alkali oxides such as K2O, Na2O (0-3 wt. %) and other small amounts (0-1 wt. %) of additives such as Fe2O3, As2O3. Fe2O3, V2O5, As2O3. Some of the ingredients (e.g. Mg, Ba, Ca) can also be present in the form of fluoride, e.g., MgF2, BaF2, CaF2, to up to 10 wt. %. Additional ceramic additives up to 30 wt. %, which are as second phase (e.g., Al2O3, Y2O3 doped ZrO2, SiO2, mullite, zircon, carbides, nitrides, and a combination of the above), are not part of the glass composition, but are introduced to enhance both the mechanical strength and toughness and to further modify the coefficient of thermal expansion. In the dry pressing process the powder is milled, blended with a binder and then subjected to a drying/granulation process. A die cavity of a desired shape is then filled with the powder. Pressure is then applied to die for a period of time. After the pressure is removed, the green ceramic part is ejected and then sintered to become a finished ceramic cover or header. In the slip casting process, the powder is milled and dispersed in a water. The slip is then poured or pumped into a permeable casting mold of a desired shape made of Gypsum. When either the liquid has been completely sucked away by the mold or the desired depositing thickness has been reached, the cast green ceramic part is removed from the mold, dried and then sintered into a finished ceramic cover or header.

    摘要： A capacitive pressure sensor capsule having a support base with a cavity is provided. The capsule includes a housing having a ceramic cover sealingly attached to a ceramic base to define an interior chamber. The base has a cavity facing this interior chamber and at least one hole adjacent the cavity that extends through the base. A glass sensor has a first diaphragm with a first electrode and a second diaphragm with a second electrode bonded together to form a capacitor and is mounted in the chamber so that one of the diaphragms is received within the cavity and the other diaphragm lies on the surface of the base and covers the hole. A conducting member extends from the sensor, through the hole to electronic circuitry mounted to the capsule. The cavity also has a land for supporting the diaphragm disposed therein.
