PURPOSE:To improve thermal efficiency and quality, by performing sintering under a specified condition, while condensing luminous energy from light sources onto a body to be sintered in the chamber of an oven using reflecting-condensing plates. CONSTITUTION:A compressed powdery body 2 is set up at a focal position in the chamber of an oven having reflecting-condensing plates 4 of parabolic cross section and light sources 3 such as infrared lamps. Said body is sintered under the condition of a temp.-raising speed at 10-150 deg.C/sec, a sintering temp. at 1,200-1,600 deg.C and a time for keeping the sintering <=20min. Hence the sintering is completed within a short time, the compressed body 2 to be sintered is not contaminated with the surrounding atmosphere, its quality is improved, and thermal efficiency is also improved. |
