Magnetic material and a method of synthesising the same

A process for producing Co, Al alloyed NdFeB nanoparticles, by a microwave assisted combustion process, followed by a reduction diffusion process, the process comprising the steps of:

• preparing a first solution of boric acid dissolved in 4 N Nitric Acid (HNO3);
• dissolving iron nitrate nonahydrate, neodymium nitrate hexahydrate, cobalt nitrate hexahydrate, aluminium nitrate, and the first solution in deionized water to form a second solution;
• adding glycine to the second solution in a molar ratio of 1:1 to form a third solution;
• subjecting the third solution to microwave radiation, thereby forming a first powder of NdFeCoAlB oxides;
• mixing the first powder with calcium hydride in a mass ratio of 1:1.1 (NdFeCoAlB oxides:CaH2) to form a second powder, compacted into a powder block;
• annealing the second powder in a vacuum furnace;
• washing the annealed second powder with a solution of ethylenediaminetetraacetic acid;
• and
• vacuum drying the second powder,
• wherein the solution of ethylenediaminetetraacetic acid is a solution of ethylenediaminetetraacetic acid in methanol and triethanolamine.
