| dc.description | An induction furnace operating at 500 kc/s is described which is capable of providing temperatures in excess of 3000° C at high vacuum or in any suitable gas mixture at pressures up to 8 atmospheres. The work coil is mounted inside the furnace chamber, which can then be designed as a pressure vessel and constructed of electrically conducting steel. By this technique close coupling is provided between the work coil and the susceptor crucible: if desired, a heat treatment cycle to 3000° C can be completed in less than one minute. To avoid any contamination, the furnace is thermally uninsulated, so that all the heat dissipated in the crucible is lost by radiation, limiting its total surface area to about 20 cm<sup>2</sup> for temperatures of 3500° C with a 25 kw generator.Application of the theory of induction heating shows that the effective resistance of the susceptor crucible can be increased by several methods, thus improving the heating efficiency of the furnace. The theory may also be applied for determining the resistivities of various susceptor materials at very high temperatures. |
