Abstract

A powder material used for a capacitor-level tantalum-niobium alloy wire material and a preparing method thereof. The powder material is formed by tantalum powder and niobium powder, wherein the weight proportion of the tantalum powder and the niobium powder is 1:2 to 3:2, the purity of the tantalum powder and the niobium powder is greater than 99.9 wt%, the granularity of the tantalum powder is -80 to -150 meshes, the granularity of the niobium powder is -150 to -200 meshes, and a loose specific weight of the powder material is 3.0 to 4.3 g/cm3. The preparing method of the powder material comprises material proportioning, manual mixing, primary mixing, secondary mixing, and tertiary mixing, thereby obtaining a powder material used for a capacitor-level tantalum-niobium alloy wire material. The preparing method is reasonably designed, and suitable for uniform mixing of two different types of metal powder materials. The whole production process is highly controlled, the product quality is stable, and the manufacturing of the capacitor-level tantalum-niobium alloy wire material is facilitated.
