The aim of the project is to develop warehouses and technological parameters for obtaining a new class of ceramic transparent materials based on system compositions RO - Al2O3 - SiO2 (where RO - BaO, SrO) with stable electrodynamic properties over a wide range of operating temperatures and radio wavelengths, which can be used to create nose cones to protect aircraft structural elements (aircraft-guided missiles or anti-aircraft missiles) at high temperatures (up to 1500 ° C). Methods of research - theoretical calculations in the diagrams of the state of oxide systems; prediction of phase composition and properties of compositions; research of physical-mechanical, electrodynamic and chemical properties of ceramic materials, methods of mathematical modeling. The choice of areas of multi - component system RO - Al2O3 - SiO2 perspective for development of compositions of radio opaque materials with low values ​​of electrodynamic characteristics, including by means of regression analysis of dependence of the basic properties that determine the functionality of radio opaque materials, from their composition is substantiated. Scope - Theoretical developments can be used to create translucent ceramic materials in space, rocket and other electronics industries. Product Description popup.authors VOLOSHCHUK VALENTYNA V.
