Abstract: A two-component microwave ferrite material, a preparation method therefor and an application thereof. The two-component microwave ferrite material comprises a first microwave ferrite material and a second microwave ferrite material. The preparation method comprises the following steps: (1) mixing a first microwave ferrite material and a second microwave ferrite material according to a formula amount, and then performing wet ball milling to obtain a ball abrasive; (2) drying the ball abrasive, sieving, and granulating; and (3) sequentially forming and sintering the granulated particles obtained in step (2) to obtain a two-component microwave ferrite material.

Abstract: The present application provides an iron-based amorphous alloy powder, a preparation method therefor and an application thereof. The iron-based amorphous alloy powder comprises a Cu element, and the particle shape of the iron-based amorphous alloy powder is spherical. The preparation method comprises the following steps: (1) smelting a master alloy to obtain iron-based amorphous alloy molten iron, the master alloy comprising a Cu element; and (2) treating the iron-based amorphous alloy molten iron obtained in step (1) by means of water-gas combined atomization to obtain the iron-based amorphous alloy powder.
