Abstract

It is elaborated the crystal growth technique on base of Cyropulos method that allows to receive the sapphire single crystals of high quality with small dislocation density, low levels of X-ray luminescence and thermoluminescence, high transparency, and high radiation resistance. The main features of developed technique are: low temperature gradient in growth zone, acute-angled crystallization front, and absence of any mechanical displacement during growing process.

Some other growing factors influencing on crystal quality are discussed.
