sintering furnace

Abstract

Abstract PURPOSE:To enable sintering at a high speed and to obtain a sintered body having high quality by installing light sources such as IR lamps or the like in the prescribed position in a hermetically sealed furnace body, and using the inside wall of the furnace body as a reflection plate having a parabolic or elliptical section. CONSTITUTION:When an object 6 to be sintered is installed on a quartz plate 13 or the like in the central part of a furnace body 1 and light sources 16, for example, IR lamps are lighted, the light is reflected on a reflection plate 15 having a parabolic or elliptical section and is fully condensed to the object 6 as shown by the rays indicated by 17. Therefore the object 6 is heated up at a high speed and the sintering under the heating-up is completed in 10-30sec. The IR lamps having the near IR radiation spectra of which the radiation wavelength has a peak roughly at 1.15mu are used.
