A temperature sensor includes a substrate, a platinum resistor arranged on at least one surface of the substrate, a protective layer covering at least a portion of the platinum resistor and a cover layer covering at least a portion of the protective layer, the cover layer including Al2O3, SiO2 and Y2O3. The cover layer may also include B2O3. A conductive wire may be electrically connected to the platinum resistor. A glass ceramic may be covering at least a portion of the conductive wire, platinum resistor, protective layer and cover layer.

A method of forming granules, the method including forming a suspension of a nanopowder such as a nano zirconia powder containing yttria. The powder is formed from a suspension, and freon is added directly to the suspension as an additive. The suspension is then granulated by spray freeze drying, and the freon subsequently removed by heat treatment. The voids left by the vacated freon provide meso, micro and macro flaws or structural defects in the granules.

Deformable granule production

Braze materials and processes for using braze materials, such as for use in the manufacturing, coating, repair, and build-up of superalloy components. The braze material contains a plurality of first particles of a metallic material having a melting point, and a plurality of second particles comprising at least one nonmetallic material chosen from the group consisting of oxides, carbides, and nitrides of at least one metal. The nonmetallic material is more susceptible to heating by microwave radiation than the metallic material of the first particles, and the nonmetallic material is present in the braze material in an amount sufficient to enable the first particles to completely melt when the first and second particles are subjected to heating by microwave radiation.

Braze materials and processes therefor

Ceramic HID lamps with improved thermal management having an adherent infrared reflective coating layer located on the outer surface of the vessel are described. They include a coating of a nonmetallic material proximate the first and second end portions of the vessel. Such coatings can minimize temperature gradients during lamp operation. Methods for preparing such lamps with improved thermal management are described as well.

Thermal management of high intensity discharge lamps, coatings and methods

Certain embodiments relate to a process for forming a multilayer electrical device. The process includes providing a multilayer structure including layers of a dielectric material and an electrode material. The electrode material may include at least one material selected from the group consisting of nickel and copper. A variety of dielectric materials may be used, such as barium titanate. The method also includes sintering the dielectric material by heating the structure using microwaves in an industrial nitrogen atmosphere, which contains an oxygen partial pressure of 10 to 10 atm.

Microwave sintering of multilayer dielectrics with base metal electrodes

A method of heating an article with microwave energy is described in which a thin layer of highly microwave absorbent powdered material is provided around at least a portion of a container made of microwave transparent material. The article to be heated is placed at a position within the container where the article is adjacent the thin layer of highly microwave absorbent powdered material, and microwave energy is applied to the container.

Microwave processing using highly microwave absorbing powdered material layers

Varistors are produced by pressing ceramic ZnO powder to provide discs, sintering the discs with microwave radiation, and firing outer electrodes with microwave radiation. The sintering has a maximum plateau temperature of 1000&deg; C. to 1300&deg; C. and the duration for ramping to this temperature and maintenance at this temperature is 120 to 180 minutes. These parameters also apply for multi-layer varistors with inner electrodes. The outer electrodes are fired at a maximum plateau temperature of 550&deg; C. to 820&deg; C. for a total duration of 40 to 45 minutes.
