Problems solved by technology

However, the molten liquid of the Fe-Co alloy is very viscous, and it is very easy to block the pipeline, resulting in the failure of the gas atomization method. In addition, there is no place to purchase Fe-Co alloy powder with the target ratio requirement on the market, so that Fe -The preparation and development of Co-based alloy sputtering targets have been greatly hindered

Embodiment 1

[0069] This embodiment provides a method for preparing iron-tantalum alloy powder, the preparation method comprising the following steps:

[0070] (1) The electrolytic iron material with a purity ≥ 99.95% and the tantalum scrap (purity ≥ 99.95%) of the tantalum target disclosed in CN102517531A are sequentially subjected to pretreatment of degreasing, pickling, drying and vacuum packaging:

[0071] First put the electrolytic iron material and tantalum scrap into an aqueous solution containing detergent, ultrasonically clean at 60°C for 60 minutes for degreasing treatment, then rinse with pure water and wipe clean; then ultrasonically clean them in the pickling solution After cleaning for 20 minutes, carry out pickling. In terms of mass percentage, the nitric acid in the pickling solution is 38.5%, and the hydrofluoric acid is 7.1%. Then rinse and wipe clean with pure water; then the electrolytic iron obtained by pickling The material and the tantalum trim were put into a vacuum...

Abstract

The invention relates to a preparation method of iron-tantalum alloy powder, the iron-tantalum alloy powder and application. The preparation method of the iron-tantalum alloy powder comprises the steps: firstly, an iron material and a tantalum material are prepared according to the target atom proportion and mixed; then a mixture is completely molten at the temperature of 1542-1600 DEG C; and thenatomization is conducted under the action of inert gas, and the iron-tantalum alloy powder is obtained. According to the preparation method, the melting temperature of the iron-tantalum mixture is controlled to be 1542-1600 DEG C, the atomization condition is optimized, the purity of the prepared iron-tantalum alloy powder is larger than or equal to 99.95%, the oxygen content is smaller than or equal to 600 ppm, and the iron-tantalum alloy powder with the particle size smaller than 150 meshes is obtained through screening; and an iron-cobalt-tantalum alloy sputtering target material with thehigh purity, high compactness, the high bending strength and the qualified magnetic flux is prepared advantageously, wherein tantalum rim charge of the tantalum target material is used as the tantalummaterial for preparation, so that waste is turned into wealth.

Description
