To achieve materials of the desired physical and chemical properties, the fabrication of nano-ferrites and nano-orthoferrites through different routes has become an essential part of research and development. Some of the best-known methods are the sol–gel process, combustion synthesis, electrochemical method, hydrothermal method, precursor route, co-precipitation, micro-emulsions, thermal decomposition, etc. Most of these methods have achieved particles of the required sizes and shapes but are challenging to use on a large scale because of expensive and complicated procedures and high reaction temperatures. NMH group wants to solve these gaps and problems by producing Nano-ferrites and Nano-orthoferrite.
