Synthesis of Materials by the Radiation Method and Their Application

The construction of the Big Solar Furnace (BSF) in Uzbekistan made it possible to obtain materials with unique properties that are difficult or impossible to obtain in any other way. In particular, ceramic materials have been developed that convert the energy of a primary source into pulsed infrared radiation with a controlled rising edge of the pulse. At the same time, the slope of the rising edge of the pulse can be viewed as part of a sinusoid. The radiation occurs as if with a pseudo-wavelength. Our long-term research has shown that this wavelength can work as the main one. However, the effect of dualism is also manifested here. The carrier energy corresponds to the main wavelength in the IR range, while the slope of the rising edge of the pulse affects only the selected processes. The use of such materials in polymerization and polycondensation processes is considered as an example. In this case, the quality of the target products is significantly improved, the energy efficiency of the process is noticeably increased, and many complex and expensive operations are completely eliminated. The paper is dedicated to this aspect of the application of functional ceramics synthesized under the action of concentrated solar radiation. In addition, comparative results are given for the effect on the processes of polymerization and polycondensation exerted by a material of the same chemical composition but synthesized in two ways: on the BSF and under the action of pulses generated by functional ceramics (FCs) synthesized under the action of FC pulses of the MC-1 type.
