Plane-elliptical mirror furnace for crystal growth
For single crystal growing in aggressive media, classical heating methods do not provide reliable results. In this study, we conceived and realized a system for radiant heating, by which the growth media is separated by the radiant and radiation focusing elements. The system is composed from an asse...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | For single crystal growing in aggressive media, classical heating methods do not provide reliable results. In this study, we conceived and realized a system for radiant heating, by which the growth media is separated by the radiant and radiation focusing elements. The system is composed from an assembly of plane-elliptical mirrors with rod-shaped halogen lamps in the first focal centers and crucible as the second focal center. The growth medium being isolated, we could employ highly oxidant atmospheres and use crucibles made of dielectric oxide materials. The results obtained show a possibility to use the system to synthesize materials in aggressive media, as well as to configure the specific temperature gradients required by these processes. |
