Abstract

The present invention relates to a tantalum-manganese-palladium alloy and a processing method thereof. The tantalum-manganese-palladium alloy is processed from the following raw materials, by weight, 33-47% of Ta, 30-45% of Mn, 1-15% of Pd, less than or equal to 0.3% of C, less than or equal to 0.04% of P, and the balance of Tc and unavoidable impurities. The processing method comprises the following steps: 1) smelting tantalum stone, carbocoal and palladium debris in a low-shaft electric furnace in batches to obtain tantalum-palladium; 2) making a metal liquid in a melting tank contain manganese, and making the melting tank remove phosphorus; and 3) casting the tantalum-manganese-palladium alloy formed through punching blending into ingots after the added materials are subjected to complete melting and reaction. According to the present invention, the processed tantalum-manganese-palladium alloy has characteristics of simple process and reasonable component design; large batch qualified tantalum-manganese-palladium alloys can be stably processed according to component requirements, and the processed tantalum-manganese-palladium alloys can be stored for a long time, and are not easily subjected to dusting; and dephosphorization capability of the tantalum-manganese-palladium alloy is slightly higher than dephosphorization capability of the conventional tantalum-manganese-aluminum alloy when the tantalum-manganese-palladium alloy is used for dephosphorization.

Description

technical field [0001] The invention relates to a tantalum-manganese-palladium alloy used as a dephosphorizing agent for technetium smelting, especially a low-phosphorus and low-carbon tantalum-manganese-palladium alloy and a processing method thereof. Background technique [0002] The traditional tantalum-manganese-aluminum alloy has been used by the technetium smelting industry for many years because of its low melting point and the advantages of easy dephosphorization products floating in technetium water. But for technetium with strict requirements, this aluminum-containing tantalum-manganese alloy is not suitable. Therefore, the technetium smelting industry urgently needs a new type of alloy that can replace the traditional tantalum manganese aluminum. An ideal substitute product for the tantalum-manganese-aluminum alloy is firstly a tantalum-manganese-palladium alloy. However, due to the very limited solubility of palladium in tantalum and manganese, when the smelted...
