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.
