METHOD FOR MANUFACTURING OXIDE DISPERSION-STRENGTHENED PLATINUM-GOLD ALLOY POWDER USING DRY METHOD

摘要

The present invention relates to a method for manufacturing platinum alloy powder used to manufacture oxide dispersion-strengthened platinum materials. The objective of the present invention is to overcome the disadvantages of existing wet and dry methods for manufacturing platinum alloy powder, such as environmental pollution problems including wastewater treatment due to the use of acids, a complicated manufacturing process, high manufacturing costs, and a long manufacturing time. To this end, the present invention obtains fine and highly-purified platinum alloy powder which is prepared by: manufacturing a platinum alloy ingot by adding an alloy element for a target composition to platinum; manufacturing platinum alloy powder using an environmentally friendly plasma process; obtaining fine and highly-purified platinum alloy powder using and performing heat treatment and classification.
