    摘要: Fused silica glass having an internal transmittance of UV with 245 nm wavelength, being at least 95% at 10 mm thickness, a OH content of not larger than 5 ppm, and a content of Li, Na, K, Mg, Ca and Cu each being smaller than 0.1 ppm. Preferably the glass has a viscosity coefficient at 1215° C. of at least 1011.5 Pa·s; and a Cu ion diffusion coefficient of not larger than 1×10−10 cm2/sec in a depth range of greater than 20 μm up to 100 μm, from the surface, when leaving to stand at 1050° C. in air for 24 hours. The glass is made by crystobalitizing powdery silica raw material; then, fusing the crystobalitized silica material in a non-reducing atmosphere. The glass exhibits a high transmittance of ultraviolet, visible and infrared rays, has high purity and heat resistance, and exhibits a reduced diffusion rate of metal impurities, therefore, it is suitable for various optical goods, semiconductor-production apparatus members, and liquid crystal display production apparatus members.

    摘要: An indium oxide-tin oxide (ITO) sintered body is prepared by mixing a tin oxide powder with an indium oxide powder, molding the resulting mixed powder to obtain a green body, and sintering the resulting green body. At least the tin oxide powder has beforehand been pulverized by colliding tin oxide particles with each other or against a collision substance in gas streams. At least 90 wt % of the pulverized tin oxide powder is preferably particles having a particle size of 0.2-10 .mu.m. A jet mill can be used for the pulverization. The ITO sintered body has a density as high as 7.08 g/cm.sup.3 or more and, during sputtering, is free from nodule formation and is inhibited from generating particles.

    摘要: A mixture of zinc sulfide and silicon dioxide as starting material powder mixed with zinc oxide in an amount of from 0.5 to 5 wt % is subjected to hot pressing sintering to obtain a sintered body. In this manner, a high density sputtering target using the sintered body can be obtained at a high yield.
