摘要： A ceramic material is a calcined article obtained by calcining a molded ceramic article and in which the pores of the calcined article are impregnated with a substance which can be removed at a temperature lower than a sintering temperature for the molded ceramic article. A method for manufacturing a ceramic product includes the steps of calcining a molded ceramic article, impregnating the open pores of the calcined ceramic article with a substance which can be removed at a temperature lower than a sintering temperature for the calcined ceramic article, mechanically machining the ceramic article to impart a desired shape thereto, removing the substance from the ceramic article, and then sintering the ceramic article. Large-sized ceramic products having a high strength and an excellent shape accuracy and having complex shapes can be manufactured at low costs. The change of the product shape can be accomplished only by changing a program for operation, and for the ceramic products having various shapes, a prompt design changing is possible.

摘要： A composite luminous vessel container 3 has a hollow and polycrystalline alumina capillary 1 and one or more transparent disk(s) 2 of monocrystalline alumina. The polycrystalline alumina luminous container member 3 functions as a luminous part for a high intensity discharge lamp. Light is emitted from the inside of the polycrystalline alumina luminous member 3 and radiated through the transparent monocrystalline alumina disk to the outside. The light emitted through the transparent window has a low loss due to the scattering so that the lamp efficiency can be improved. In the case of the light emitted through the transparent monocrystalline alumina, the size of the light source is substantially equal to the distance between the electrodes, so that the light source can be utilized as a point light source. The light emitted from the point light source can be subjected to optical control by combination with reflectors or lenses.
