溶解在纯铜中的氧化物一般是Cu_2O,因此铜合金的脱氧就是使铜液中的Cu_2O还原,即加入一种与氧亲和力比铜和氧亲和力大的元素,将Cu_2O还原成Cu,生成的氧化物上浮至液面成渣而被排除.这就要求脱氧剂的氧化物分解压力小于Cu_2O,且氧化物的分解压力与Cu_2O分解压力相差越大,则脱氧反应进行得越完全,效果越好.在工业生产中,常用磷做为脱氧剂来熔炼纯铜,但由于固溶磷会严重恶化纯铜的导电性能,很难达到脱氧和导电性能兼得的最佳效果.因此需要寻找一种不仅能达到良好脱氧效
The oxide dissolved in pure copper is generally Cu_2O, so the deoxidation of copper alloy is the reduction of Cu_2O in the copper solution by adding an element with higher affinity to oxygen than copper and oxygen, reducing Cu_2O to Cu, The oxide floating up to the surface of the slag and was excluded.This requires deoxidizer oxide decomposition pressure is less than Cu_2O, and the decomposition pressure of the oxide and the decomposition pressure of Cu_2O greater the deoxygenation reaction proceeds more completely, the better In industrial production, phosphorus is often used as a deoxidizer to melt pure copper, but it is difficult to achieve the best deoxidization and electrical conductivity due to the serious deterioration of the electrical conductivity of pure copper due to solid solution phosphorus. Therefore, it is necessary to find a Not only can achieve good deoxy effect
