  • Chromium-Base Alloy and a Production Process Therefor
    Publication number: 20080124241
    Abstract: A chromium-base alloy characterized by containing titanium within a range from 0.002 t0 1.5 mass %, with the balance comprising chromium and inevitable impurities, and being produced by melting or casting only. A chromium-base alloy that can be obtained by melting only, has room temperature ductility and a good workability, and has excellent high temperature strength and oxidation resistance even at a high temperature of about 1300° C., as well as a production process therefor are provided.

  • Process for producing tin oxide fibers
    Patent number: 4725331
    Abstract: A process for producing tin oxide fibers, which comprises forming a melt comprising a solute composed essentially of tin oxide and a solvent selected from the group consisting of copper, a copper alloy, tin or a tin alloy, evaporating the solute from the melt, and introducing the evaporated solute to a low temperature zone, whereby tin oxide fibers are permitted to precipitate and grow in the low temperature zone.
