METHOD TO MANUFACTURE NICKEL PARTICLES IN MICROSIZE COATED WITH SILVER USING NON-TRANSFERRING THERMAL PLASMA METHOD

摘要

The present invention relates to a method of manufacturing nickel (Ni) particles in a microsize coated with silver (Ag) using a non-transferring thermal plasma method. The method of the present invention comprises: a step of preparing a non-transferring thermal plasma apparatus including a reaction tube, a reactor connected with the reaction tube, a plasma torch generating a plasma jet in the reaction tube, a DC power supply unit supplying power to the plasma torch, and a raw material supply unit supplying powder into the reaction tube; a step of placing nickel (Ni) powder and silver (Ag) powder into the raw material supply unit; a step of supplying nickel (Ni) powder and silver (Ag) powder into the reaction tube from the raw material supply unit; a step of generating a plasma jet by the plasma torch by supplying power by a DC power supply unit; and a step of coating silver (Ag) on a surface of nickel (Ni) powder in the reaction tube.;COPYRIGHT KIPO 2016
