Flaky Powder for an Electromagnetic Wave Absorber, and Method for Producing Same |
摘要 |
A flake powder for an electromagnetic wave absorber and a method of manufacturing the flake powder are described. The flake powder is made-up of nano-sized metals and pores forming a flake body having a composite structure formed by aggregation of nano-sized magnetic metals. The method includes the steps of preparing a metal oxide; milling the metal oxide into nano-sized powder; reducing the milled metal oxide powder to form a magnetic metal powder; flaking the reduced magnetic metal powder; and heat treating the flaked magnetic metal powder to relieve residual stress thereof.
