DEBUGGED METHOD OF GROWING AND HIGH QUALITY SYNTHETIC QUARTZ MONOCRYSTAL

Debugged METHOD OF GROWING AND HIGH QUALITY synthetic quartz monocrystal

In the Federal State Unitary Enterprise All-Russian Scientific Research Institute of Synthesis of Mineral Resources to fine tune the technology of crystal growth, which reduces the density of growth dislocations or get completely bezdislokatsiionnye synthetic quartz crystals, namely, large single crystals of quartz and quality, used mainly for the manufacture of a variety of technical Device in modern electronics.


Known methods for growing crystals or contain such linear defects, the so-called dislocation growth (often of very high concentration), which adversely affect the technical characteristics of the crystals or crystals allows to obtain, which differ sectorial inhomogeneous structure in which growth of the pyramid faces have shapes different prime Various physical properties. In addition, recent growth include dislocations, reducing their quality.


Employees of Federal State Unitary Enterprise VNIISIMS - Gordienko LA, Dorogovinym BA, Orlov O., E. Polyansky, Tsinober LI PP and Shvanskim managed to reduce the density of growth dislocations and get completely dislocation-free synthetic quartz crystals with a view to their use in modern industrial technology.


This problem has been solved by them due to the fact that in the process of growing quartz crystals by hydrothermal synthetic method, recrystallization comprising quartz charge on the seed rod at a temperature differential between the growth chamber and dissolution are used seed rod oriented with its length along the crystallographic direction, the side rod side primers or four contoured edges main negative rhombohedral or two faces of the positive and negative trigonal prism and two second edges rhombohedral or cylindrical. In addition, the seed rod made of malodislokatsionnyh or dislocation-free regions previously grown crystals.


This technology allows us to grow malodislokatsionnye or completely free of growth dislocations large crystals of synthetic quartz, which can be used in various technical devices electronics.
