“…Especially, nano-dots are expected, now in the nano-materials. There are some production methods of nano-dots, such as Inert gas evaporation method [1][2][3][4][5][6] , Hydrothermal synthesis method [7][8][9][10][11][12][13] , Mechanical grinding method [14][15][16][17][18][19][20] , Microwave-Induced Plasma in Liquid method [21][22][23][24][25][26][27] .…”

New production method of nano-crystals was proposed. Over the past few decades, with improvements in nanotechnology, production of nano-materials had been paid interest markedly. There are some production methods of nano-materials, such as inert gas evaporation method, hydrothermal synthesis method, mechanical grinding method and etc. In recently, solution plasma method was developed, in that method nano-crystals were produced by microwave induced plasma in liquid. The authors have found new nano-crystal production method. In the new method, nano-crystals were produced by application of relatively low voltage DC current in aqueous electrolyte solution. The various combinations of electrodes (Au, Cu, W, Si, etc.) and aqueous electrolyte solution (Na 2 SiO 3 , Na 2 CO 3 , Na 2 SO 4 , etc.) were tested to produce nano-crystals. After few tens minutes of current application, precipitated materials were gathered and identified by X-ray diffraction analysis and TEM observation. From XRD analysis and TEM observation, it was found that the collected materials were nano-crystals of around few tens nm of the same material as the electrode. From measurement of mass change of electrode before and after DC current application, it turned out that nano-crystals were generated from the electrode to which the positive voltage was applied.

“…[1][2][3] Fe-9?5Si-5?5Al alloy is called a Sendust, which is suited for a magnetic head for video tape recorder because of its high permeability, high magnetic flux density and high wear resistance. 4 However, the applications of this alloy have been limited due to its poor workability. The production feasibility of Fe-9?5Si-5?5Al alloys is discussed, by MIM process, and is investigated in detail to obtain high performance magnetic properties by taking the microstructures into account.…”

Powder metallurgy is an effective way to produce the complex shaped soft magnetic materials, and also to decrease the eddy current loss in high frequency by subdividing the eddy current area due to the small grains. Especially, metal injection moulding (MIM) process allows nearly full dense and net shaping of a variety of engineering materials. The application of MIM process to hard and brittle materials such as ferromagnetic materials demonstrates the potential of this novel process. This study considers the processing of three types of soft magnetic materials such as Fe-6?5Si, Fe-9?5Si-5?5Al and Fe-50Ni alloy compacts through the MIM techniques using different types of powders to obtain high performance of soft magnetic properties.
