    Abstract: Disclosed are a lead-free, high-sulphur and easy-cutting copper-manganese alloy and preparation method thereof. The alloy comprises the following components in percentage by weight: 52.0-95.0 wt.% of copper, 0.01-0.20 wt.% of phosphorus, 0.01-20 wt.% of tin, 0.55-7.0 wt.% of manganese, 0.191-1.0 wt.% of sulphur, one or more metals other than zinc that have an affinity to sulphur less than the affinity of manganese to sulphur, with the sum of the contents thereof no more than 2.0 wt.%, and the balance being zinc and inevitable impurities, wherein the metals other than zinc that have an affinity to sulphur less than the affinity of manganese to sulphur are nickel, iron, tungsten, cobalt, molybdenum, antimony, bismuth and niobium. The copper alloy is manufactured by a powder metallurgy method, in which after uniformly mixing the alloy powder, sulphide powder and nickel powder, pressing and shaping, sintering, re-pressing, and re-sintering are carried out to obtain the copper alloy, and the resulting copper alloy is thermally treated.

    Abstract: The present invention provides a process for preparing a tantalum powder with high specific capacity, which process comprising the steps of, in sequence, (1) a first reduction step: mixing tantalum oxide powder and a first reducing agent powder homogenously, and then carrying out reduction reaction in hydrogen and/or inert gas or vacuum atmosphere to obtain a tantalum suboxides powder; (2) a second reduction step: mixing the tantalum suboxides powder obtained from the step (1), in which impurities have been removed, and a second reducing agent powder homogenously, and then carrying out reduction reaction in hydrogen and/or inert gas or vacuum atmosphere to obtain a tantalum powder having high oxygen content; (3) a third reduction step: mixing the tantalum powder having high oxygen content obtained from the step (2), in which impurities have been removed, with a third reducing agent powder homogenously, and then carrying out reduction reaction in hydrogen and/or inert gas or vacuum atmosphere to obtain a tantalum metal powder suitable for capacitors; wherein after each reduction step, the oxidation product of reducing agent and the residual reducing agent are removed from the reaction product.
