History of the Department
The Department of Synthesis and Sintering of Superhard Materials at Extreme P, T Parameters was established in 1981 on the basis of Laboratory No. 1, the main tasks of which were the synthesis of diamond and cubic boron nitride, as well as the creation of superhard polycrystalline materials based on diamond and cubic boron nitride. In 1961, an original technology for obtaining synthetic diamonds was created in Laboratory No. 1. The efforts of the department’s employees have created dozens of varieties of superhard materials, developed new designs of high-pressure and high-temperature equipment for the synthesis of superhard materials, competitive in the world market.
Main scientific directions
Establishment of regularities of crystallization, solid-phase, liquid-phase and conversion sintering of materials at high pressures. Study of thermodynamics, kinetics, mass transfer processes and structure formation of materials based on diamond, cubic boron nitride, carbides, boride and nitride. Development of technologies for creating superhard materials at high pressures.
Tasks of the department
- conducting scientific fundamental, exploratory and applied research in the field of materials science of superhard materials and extreme technologies associated with high pressure, studying the effect of high pressures on matter in order to develop a priority direction of science;
- comprehensive scientific research into the processes of creating new superhard materials, including nanostructured ones, synthesis and sintering of diamond, cubic boron nitride and other superhard materials;
- studying phase transformations and phase equilibria in systems with diamond-like materials at high pressures and temperatures;
- studying the structure formation and formation of increased physicomechanical and chemical properties of polycrystalline materials under high pressure conditions;
- development of new composites based on diamond and cubic boron nitride with a certain level of physicomechanical characteristics;
