Abstract
Official abstract text for this publication.
A hydrogen vacuum furnace ( 100 ) is provided with a process chamber ( 1 ) wherein a subject ( 10 ) to be heated is stored; a heating chamber ( 2 ) wherein a heater lamp ( 25 ) is stored; and a crystal board ( 3 ) for separating the subject ( 10 ) and the heater lamp ( 25 ) one from the other. In the hydrogen vacuum furnace ( 100 ), the subject ( 10 ) is heated by a radiant ray applied from the heater lamp ( 25 ). The process chamber ( 1 ) and the heating chamber ( 2 ) are provided with gas feed ports ( 11, 21 ) and exhaust ports ( 12, 22 ), respectively, for feeding and exhausting a gas. When the subject ( 10 ) is being heated, atmospheric pressure in each chamber is adjusted so that the heating chamber ( 2 ) is under positive pressure to the process chamber ( 1 ) by feeding or exhausting the gas.
