Ideal Single Crystal
Ultra-perfect or "ideal" single crystal is a volumetric crystalline system with completely faceted crystallization frontline, free from defects with high transparency level.

Ultra-Perfect Single Crystals

Crystals are the most eagerly sought, expensive and at the same time deficient component of modern tools. Crystal is able to generate laser beam, detect ionized radiation, transform solar light into electricity etc. Nevertheless, scientific and technological progress demands higher level of perfectness and enhanced specifications of single crystals.

Crystals has no lifetime – however, majority of market fields are currently experiencing ever-growing shortage of high-quality flawless single crystals due to energy intensive methods of their growth and large amount of waste produced during the synthesis.

The Platform for Synthesis of Single Crystals Includes:

  • The technology of single crystals growth "Exceptional Environment"
  • Unique chambers for single crystals growth
  • Own scientific school in the field of single crystals growth

Exceptional Environment
Growth technology

ADGEX VITIM designed an innovative technological platform for synthesis of "ideal" large-format and oriented single crystals.
Universality
Conversely to all current growing technologies of crystals, when they are simply pulled unless desired shape and size are reached, our technology "Exceptional Environment" is based on the method of layer-wise growth in naturally established environment.
Uniqueness
The crystals, grown under the technology "Exceptional Environment" feature greater specifications against analogues currently presented on the global market.
Equipment
Unique chambers, expressly designed for our technology "Exceptional Environment", allows growing structurally "ideal" single crystals of up to 260 mm in diameter and 500 mm in height.

Present Time

We are aimed at production of high-quality large-format scintillating crystals - cadmium tungstate (CWO) and zinc tungstate (ZWO). Cadmium tungstate CdWO4 is the cadmium salt of a tungstic acid. Cadmium tungstate is a dense, solid, insoluble in water and inorganic acids, chemically inert crystal.

Ultra-pure single crystals CdWO4 are transparent and colourless. The density is 7.9-8.0 g/cm3, melting temperature – 1271oC, refraction coefficient is 2.2-2.3; Mohs hardness is 4-4.5, non-hygroscopic. CWO is one of the densest and quick scintillators.

Applications

Single crystals of cadmium tungstate are widely used in medicine (particularly in tomography), x-ray safety systems, customs screening systems for inspection of oversized cargoes (containers, vehicles, vessels, aircraft), for detection of ionizing radiation in nuclear physics and particle physics.
