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.

Abstract: A composition comprising an admixture of at least platinum particles and metal nanoparticles of metal that, when in admixture with the platinum particles, beneficially alters the characteristics of the platinum, including metals selected from one or more of the metals in groups 3-16, lanthanides, combinations thereof, and/or alloys thereof. The composition could be used to form an ink that further comprises an ionically conductive material, such as a polymer, capable of ionic networking throughout the ink composition so as to create a substantially structurally coherent mass without significantly impacting the reactivity of a substantial number of the nanoparticles. In one application, the ink may be used to form a catalyst whereby the ink is applied to an electrically conductive backing material, such as carbon paper or fibers.
