    Abstract: A method of producing a substrate having a frosted appearance, an article having a frosted appearance and frost-imparting compositions are disclosed. The method includes applying a frost-imparting composition onto a ceramic substrate and firing the coated substrate above 400° C. to impart the frost appearance. The frost-imparting composition comprises a liquid vehicle, 20% to 90% by weight of glass frit particles and less than 10% by weight of at least one gas-releasing material, inactive below an activation temperature of at least 400° C. The gas releasing material may include carbonate, nitrate, iodate, bromate, chlorate, fluoride, manganate, dimanganate and sulfate compounds. The firing temperature is chosen to be above the activation temperature of the gas-releasing material, above which the gas-releasing material yields gas bubbles and above a temperature that causes the glass frit particles to behave as a viscous liquid.

    Abstract: The present invention improves the oxidation resistance of an ultrafine metal powder for use in the internal electrode of a multilayer ceramic capacitance and suppresses an increase in the thickness of a metal internal electrode film resulting from the spheroidization of the molten metal under surface tension during the formation of the metal internal electrode film. The ultrafine metal powder has a sulfur-containing compound of not less than one element selected from the group consisting of Y, Zr, and La present on the surface of the particle thereof and is produced by performing an ultrafine metal powder purification step of dispersing the ultrafine metal powder in a slurry, a surface treatment step of adding an aqueous solution containing a sulfate of not less than one element selected from the group consisting of Y, Zr, and La to the slurry to form the compound on the surface of the metal particle, a filtering step, and a drying step.

    Abstract: Barium titanate-based compositions having a high tetragonality and methods of forming the same are provided, as well as devices formed from the compositions. The barium titanate-based compositions advantageously have a high tetragonality and small particle sizes. For example, in some embodiments, the barium titanate-based compositions have a tetragonality of greater than about 2.0 and an average particle size of less than about 0.3 micron. Some methods involve achieving high tetragonality by limiting the concentration of certain metals (other than barium or titanium) in the compositions and/or heat treating the compositions at relatively high temperatures. In some methods, the A/B ratio of the composition may be adjusted prior to heat treatment to ensure that a small particle size is maintained during heat treatment.

    Abstract: Methods of heat treating barium titanate-based particles are provided, as well as compositions and devices formed from the particles. The methods involve forming a coating on surfaces of barium titanate-based particles and heating the coated particles, for example, to a temperature of greater than about 400° C. and less than about 1150° C. The heating step may increase the bond strength between the coating and barium titanate-based particles, reduce the average specific surface area of the coated particles, remove water present in the coating, and remove other contaminants from the composition, amongst other advantages. These effects of heat treating can improve the performance of devices (e.g., MLCCs) that include dielectric layers formed from the barium titanate-based particles.

  • Patent number: 4699849
    Abstract: A metal matrix composite is produced by plastically deforming a metal powder, either before or after blending the powder with ceramic fibers, and compacting the mixture at elevated temperatures to achieve substantially full density. Imparting strain energy to the metal allows reduction of the compaction temperature to eliminate reaction between the fibers and the metal or degradation of the fibers. Silicon nitride fibers are thermodynamically superior for use in aluminum or titanium metal matrix composites, since silicon nitride fibers are more stable at the temperatures required for full compaction. Secondary phase reactions are avoided.

  • Patent number: 4349721
    Abstract: There is provided an improved basic coated welding rod for downhand welding of fixed pipes. The coating contains by weight on a dry basis 22 to 28% of calcium carbonate, 1.5 to 3% of calcium fluoride, 7 to 14% of titanium dioxide, 35 to 55% of iron, and 5 to 25% of at least one element selected from the group consisting of chromium, manganese, silicon, nickel and molybdenum. The ratio of the coated welding rod diameter to the core wire diameter is between 1.45:1 and 1.70:1. Preferably the ratio of calcium carbonate to calcium fluoride in the coating is between 10:1 and 20:1. Advantageously, at least 35% of the iron in the coating is iron powder.

  • Patent number: 4322459
    Abstract: The invention is directed to resins which are the reaction product of an amino or mercapto substituted azole and a polyepoxide wherein the ratio of equivalents of the azole to the polyepoxide is from about 0.5:1.0 to about 1.5:1.0, preferably from about 0.9:1.0 to about 1.1:1.0. The resins can be acid or base solulized depending on whether amino or mercapto substituted azoles were used in their preparation. The invention is also directed to storage stable compositions which cure at relatively low temperatures in short periods of time comprising specified amounts of the resin containing azole-functionality, polyepoxides, organic solvents, and optionally pigments and additives.

  • Patent number: 4283452
    Abstract: A polyester fiber textile material made by the application of titanium dioxide pigment thereto is provided. According to the process by which the textile material is made, the titanium dioxide pigment having a particle size of at least about 0.18 micron is exhausted from a dispersion of same onto the textile material at a pH below approximately 7.5. Subsequent heat setting of the polyester textile material improves retention of the titanium dioxide pigment.

  • Patent number: 4131784
    Abstract: The present invention relates to a coated welding electrode containing at least 0.5% of Cr based on the total weight of the welding electrode and comprising a metal core and a coating flux composition. In this welding electrode, the content of Na and K components in the coating flux calculated as (Na.sub.2 O + K.sub.2 O) is reduced below 1% based on the total weight of the coating flux composition, whereby amounts of fumes generated at the welding step, especially the amount of toxic soluble Cr, are suppressed and minimized.
