style="text-indent:25px">電解法在金屬鹽水溶液中通以直流電、金屬離子即在陰極上放電析出，形成易于破碎成粉末的沉積層。金屬離子一般來源于同種金屬陽極的溶解，并在電流作用下自陽極向陰極遷移。影響粉末粒度的因素主要是電解液的組成和電解條件（見水溶液電解）。一般電解粉末多呈樹枝狀，純度較高,但此法耗電大,成本較高。電解法的應(yīng)用也很***，常用來生產(chǎn)銅，青海定制粉末哪里有、鎳、鐵，青海定制粉末哪里有、銀、錫、鉛、鉻、錳等多種金屬粉末；在一定條件下也可制取合金粉末。對于鉭、鈮、鈦、鋯、鈹、釷，青海定制粉末哪里有、鈾等稀有難熔金屬，常采用復(fù)合熔鹽作為電解質(zhì)（見熔鹽電解）以制取粉末。定制冶金粉末那個(gè)公司有實(shí)力！青海定制粉末哪里有</p><div

style="text-indent:25px">羰基法將某些金屬(鐵、鎳等)與一氧化碳合成為金屬羰基化合物，再熱分解為金屬粉末和一氧化碳。這樣制得的粉末很細(xì)（粒度為幾百埃至幾個(gè)微米），純度很高，但成本也高。工業(yè)上主要用來生產(chǎn)鎳和鐵的細(xì)粉和超細(xì)粉，以及Fe-Ni、Fe-Co、Ni-Co等合金粉末。直接化合法在高溫下使碳、氮、硼、硅直接與難熔金屬化合。還原－化合法則是用碳、氮、碳化硼、硅與難熔金屬氧化物作用。這兩種方法都是常用的生產(chǎn)碳化物、氮化物、硼化物和硅化物粉末的方法。青海定制粉末哪里有定制粉末哪家做得好！</p><div
