USE OF SOLAR FURNACES UNDER ORBITAL-FLIGHT CONDITIONS
E. M. Ovsyannikov UDC 621.316.72-83.017.71 ([15] 002; 620.2 [15]) Use of direct solar heating under space conditions for the production of materials with prescribed properties has a number of advantages over resistance and optical heaters used earlier for these purposes. Using SP-1.0 and Zenit SP-01-5 furnaces designed for the Alpha international space station as examples, the author analyzed the technical capabilities of solar furnaces as compared to resistance and optical heaters under space conditions in the production and investigation of: disilicides of transition metals of high purity; compositions based on the Al-Pb system, which is an antifriction material; photostimulated epitaxial films; crystals of CdTe and Bi2Te3 from melts; tantalum disilicide; single crystals of high-temperature superconductors and other materials.
