Synthesis and Thermophysical Properties of Ceramics Based on Magnesium Gallate
A ceramic was produced from a nanocrystalline magnesium gallate powder synthesized by the gel combustion method, and the thermal diffusivity of the ceramic at high temperatures was experimentally investigated. The phase and chemical composition of the MgGa 2 O 4 ceramic powder was studied by X-ray p...
