摘要： A waveguide includes a body of material having a width, a thickness, and a length, where the width is orthogonal to the thickness, and the length is orthogonal to the thickness and the width. The material includes polycrystalline ceramic that is transmissive such that the body is configured as a waveguide. The thickness is no more than 5 millimeters and at least 20 nanometers, the width is greater than or equal to the thickness, and the length is at least 100 times greater than the width. The body of material has a granular profile such that grains of the material protrude generally outward from a surface of the body with a height of at least 25 nanometers and no more than 100 micrometers relative to recessed portions of the surface of the body at boundaries between the grains.

摘要： A translucent polycrystalline sintered body is mainly composed of an alumina, is suitable for the manufacture of an arc tube for a high-intensity discharge lamp, and has an average grain diameter of 35 to 70 μm, preferably 50 to 60 μm. In a case where the sintered body is in a 0.5-mm-thick flat plate shape, the in-line transmittance of the sintered body is 30% or more, preferably 50% or more. In this case, the ratio between maximum and minimum in-line transmittance values is 2:1 to 1:1 in the visible region of 360 to 830 nm. The bending strength of the sintered body is 250 MPa or more, preferably 300 MPa or more.

摘要： A translucent polycrystalline material suitable for use in ceramic discharge vessels for metal halide lamps is produced by sintering an alumina powder doped with a MgO sintering aid in a nitrogen atmosphere containing a partial pressure of a vapor phase carbon-containing species. The sintered polycrystalline alumina has a grain boundary phase containing aluminum, oxygen and nitrogen. The formation of the AL—O—N grain boundary phase is believed to facilitate the transport of nitrogen from entrapped pores during sintering. Preferably, the PCA is sintered in a carbon-element furnace under flowing ultra-high-purity nitrogen.

摘要： The present invention uses a post-sinter-HIP anneal to increase the total transmittance of ceramic discharge vessels comprised of a submicron-grained alumina doped with MgO. After the anneal, the submicron-grained alumina discharge vessels have high values of both total and in-line transmittance, and are thus suitable for use in focused-beam, short-arc lamps. In particular, the total transmittance of the discharge vessel is increased to greater than 92% in the wavelength range from about 400 nm to about 700 nm.
