Main scientific directions: basic mineralogy; genetic mineralogy; regional mineralogy; structural mineralogy.
The department conducts analytical work in two directions.
The first is related to X-ray analysis, and the second - to the study of the chemical composition of degassing products of intermittent heating of solids (minerals, synthetic materials) up to 1050ºС, which takes place in inert gas (helium); with the reconstruction of the temperature, fluid pressure, and chemical composition of the medium in which transparent natural and synthetic crystals grew.
In the first directionзthe following types of work are performed with the help of X-ray machines for the study of minerals: DRON -2, DRON - 3M, ADP -1, URS -55, URS -60:
а) яqualitative and quantitative X-ray phase analysis of natural and synthetic crystals, polycrystalline materials (in particular, clays, cements, etc.);
b) study of the structural state of minerals (ordering, twinning, disintegration of a solid solution);
c) determination of crystal substructure parameters (mosaic, degree of crystallinity, microdeformations);
d) study of epitaxial structures;
e) structural control of micro impurities and others.
Information in the second direction is obtained using:
а) an original installation of our own modification for the chemical analysis of gases obtained during heating of a solid substance in an inert atmosphere, which are gradually released from them in the range from 50 to 1050 °С. Its basis is the LHM-8MD chromatograph with a cryo-attachment and the original gas scheme for feeding the gas obtained in a certain way into the chromatograph;
b) a medium-temperature thermal chamber (20-700 ±2 °С);
c) a high-temperature thermal chamber (20-1300 ±20 °С);
d) a device for determining the temperatures of homogenization of inclusions by their hardening (20-1400 ±20 °С);
e) cryochamber (+200…- 196 ±0,2 °С).
Visual examination of inclusions in crystals is an important element in the reconstruction of the conditions of formation of the studied crystals.
