A sharp restriction on the export of rare earth element products from China has shown the complete dependence of Russian enterprises using the products of this industry on imports. The need for an early transition to the production of a range of domestic REM products from Russian raw materials became obvious. Since 2012, the Lantan Technology Center, together with Novosibirsk State University, has started research on working out schemes for processing industrial waste and extracting REM. To ensure productive work, a powerful joint center for chemical analysis was created on the basis of the university, which has in its fleet the most modern devices capable of detecting most elements of the periodic table with a detection limit of less than 0.1 ppm. For the same purpose, an enlarged experimental base equipped with modern industrial equipment, including experimental sites for extraction, hydrometallurgy, organic synthesis, metallurgy, has been created on the basis of the research department of the Lantan Central Research Center, where the research results are tested in semi-industrial conditions.
The merger of the commercial interests of the Lantan Central Research Center and the scientific potential of the NSU led to the rapid and effective work of the research team. In less than a year, a technology for producing high-purity oxides of cerium, lanthanum, neodymium, and samarium has been developed and implemented for the production of products in Lanthanum workshops. These products have already begun to arrive to consumers in the Russian Federation, including defense enterprises. During the same period, studies on the utilization of spent iron oxide catalysts that accumulate at organic synthesis enterprises led to the fact that the metallurgical section of the Lantan Central Processing Plant began to produce ligatures containing REM from them for the needs of ferrous metallurgy.
To date, methods of obtaining and producing organometallic compounds of REM used in the production of catalysts and LEDs are at the research stage.

Crystals of Siberia LLC
Crystals of Siberia LLC, a leading manufacturer of optical elements for laser technology in Russia, Crystals of Siberia LLC and Novosibirsk State University are working together on the development and manufacture of electro-optical laser radiation control devices.
Currently, electro-optical modulators and other devices based on crystals of KTR(potassium titanal phosphate) RTP (rubidium titanal phosphate), BBO (beta boron boron) and LVO(lithium triborate) are of particular interest.Electro-optical devices based on these crystals are increasingly being used in modern laser systems, thanks to a rather successful combination of good electro-optical characteristics and the technological possibility of obtaining large perfect crystals.This allows obtaining laser pulses with a duration of 1 without any problems- 20 ns at a repetition rate of up to 1 MHz and an average power of up to 10 watts. However, the technology of obtaining these crystals and manufacturing devices based on them is currently not provided with methods and devices for quality control of crystals and devices based on them.
To solve these problems, NSU, together with Crystals of Siberia LLC, purchased equipment and created stands in 2016 that allow monitoring the parameters of crystals and electro-optical devices based on them.The control stand for optical uniformity and the degree of monodomainness in crystals is designed to measure the key parameters of crystals, selection and certification of crystal blanks.The electro-optical devices contrast control stand is designed to evaluate ready-made devices assembled, as well as to test electro-optical systems in operating modes. The crystal monodomainization stand is designed to correct the domain structure in grown crystals.
The presence of these stands and the work carried out on them in the chain of NSU— OOO "Crystals of Siberia" significantly improve the technology of manufacturing electro-optical elements for laser technology, and also contribute to the training and consolidation of young scientific and technological specialists.
The industrial partner is CJSC Siberian Single Crystal - EXMA, engaged in small-scale production of laser radiation control devices based on nonlinear single crystals.
Research agreement 2017-2019 in the amount of 4.8 million rubles. "Development of a technique for defect-free polishing of functional surfaces of optical materials for the production of laser radiation control devices."
Progress in modern optics and photonics, the development of powerful sources of laser radiation of a wide range significantly increase the requirements for the surface quality of optical materials. The aim of the work is to develop a technique for superfine treatment of ultra-smooth (with residual RMS roughness Rq<0.5 nm) functional surfaces of nonlinear single crystals of potassium titanyl phosphate KTiOPO4 (KTP), lithium triborate LiB3O5 (LBO), barium beta-borate β-BaB2O4 (BBO) using accelerated argon cluster ions.
It is known that cluster ions make it possible to form an intense flow of matter onto a target with a very low specific kinetic energy of particles. For example, with a cluster size of 1000 atoms and a total kinetic energy of an ion of 10 keV, the specific energy per atom in the cluster is only 10 eV, which is comparable to the binding energy of particles on the surface. When a gas cluster collides with a solid surface, nonlinear processes of collective interaction of a large number of cluster particles with approximately the same number of target particles occur. This leads to effective spraying of the surface with minimal damage to the subsurface structure of the target. The use of an inert gas (in particular, argon) completely eliminates the chemical reactions of cluster particles with the processed material. The works are carried out on the equipment of the OPF FF of the NSU "KLIUS".
