IR transmission spectroscopy, X-ray phase analysis, chemical substantial analysis, thermal evaporation of materials in vacuum and determination of optical and operational parameters of coatings were used as research methods. It has been established that the addition of Boron oxide, due to the formation of complex oxides such as metal borates, promotes the evaporation of CVD - composites of the Germanium - metal oxide (sulfide, fluoride) composition in a satisfactory technological mode and the production of thin-film coatings with enhanced optical (optical transparency, stable refractive index) and operational (mechanical durability, climatic resistance) properties and high reproducibility. This is especially noticeable in the systems Germanium - Germanium dioxide - Boron oxide and Germanium - Zinc sulfide - Boron oxide, in which the mechanical durability under the action of the Boron oxide additive increases several times with a simultaneous sharp increase in climatic resistance due to an increase in adhesion to the substrate. The results of the work should be applied in optical instrumentation by using the developed materials in the creation of optical elements coated with coatings such as IR spectral dividers and cut-off filters with a long storage and operating time. The use of new materials in optics of the infrared range will open up prospects both for peaceful purposes (household appliances, astronomical devices) and for strengthening the defence capability of the state, and will help to increase the prestige of domestic science and technology. For this purpose, in the future, it is envisaged to develop normative technological documentation. Product Description popup.authors Ieriomin Oleg G. Volchak Ganna V. Doha Pavlo G. Zseltvai Ivan І.
