Abstract
The results of an experimental study of the thermal expansion of gallium garnets Gd3Ga5O12, Gd3.04Sc1.8Ga3.16O12, and Ca3Nb1.5Ga3.5O12 in a wide temperature range (293.15–1473 K) are presented. A noticeable effect of niobium in the structure of gallium garnets on the thermal expansion coefficient has been found. The temperature dependences of the volumetric properties have been obtained.
期刊介绍：
The journal Thermophysics and Aeromechanics publishes original reports, reviews, and discussions on the following topics: hydrogasdynamics, heat and mass transfer, turbulence, means and methods of aero- and thermophysical experiment, physics of low-temperature plasma, and physical and technical problems of energetics. These topics are the prior fields of investigation at the Institute of Thermophysics and the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (SB RAS), which are the founders of the journal along with SB RAS. This publication promotes an exchange of information between the researchers of Russia and the international scientific community.
