Production of ceramics (Ni0.5,Zn0.5)Fe2O4 by hot pressing of SHS powders
摘要
A method for the synthesis of ferrites with the structure of the spinel mineral was developed by the method of self-propagating high-temperature synthesis (SHS). Different fuel-oxidizer ratios were used for the synthesis. For the first time, ceramics of the composition (Ni0.5Zn0.5)Fe2O4 was obtained by hot pressing of SHS-powders at different temperatures and studied by microscopic methods. The mechanical properties of the ceramics, such as hardness and fracture toughness, at different sintering temperatures were studied and the optimal temperature for obtaining the ceramics was found.
