Preparation and characterization of nano-crystalline LiNi0.5Co0.5VO4 by tartate precursor combustion method

LiNi0.5Co0.5VO4 has been successfully synthesized by tartate precursor combustion method using Li2CO3, Co(NO3)2.6H2O, Ni(NO3)2.6H2O and NH4VO3 as a starting materials in deionized water with the subsequent calcination at 450-600 oC for 12 h. The combustion and decomposition of tartate precursor were studied by TGA and compared with tartaric acid. It found weight loss at 50-450 oC. The product s...

Microwave assisted ignition to achieve combustion synthesis

The use of microwave heating to initiate combustion synthesis has been increasingly investigated in recent years because of its advantages over traditional methods. A simple mathematical model is used to model these experiments. The microwave power absorption term is modelled as the product of an Arrhenius reaction term with a function that decays exponentially with distance. The former represe...
