銻的用途和需求量擴(kuò)大，繼開發(fā)錫礦山之后又先后開發(fā)了湖南桃江板溪、新邵龍山、桃源沃溪等地銻礦，使湖南銻業(yè)居全國(guó)首要。接著，黔、滇、桂等省區(qū)也相繼開采一些銻礦。從1908年以后數(shù)十年間，中國(guó)產(chǎn)銻量常占世界總產(chǎn)量50%以上，*就錫礦山自1912—1935年間的銻品產(chǎn)量占世界產(chǎn)量的，占全國(guó)的。1942年中國(guó)有名的有色金屬冶金學(xué)家，世界**早的銻冶金**之一王寵佑與美國(guó)人霍德森(Hodson)共同取得飄浮熔煉—?dú)鈶B(tài)還原熔煉的專利權(quán)。新中國(guó)成立之后，對(duì)銻礦進(jìn)行了大規(guī)模的地質(zhì)勘探和開發(fā)，并發(fā)展了硫化銻精礦鼓風(fēng)爐揮發(fā)熔煉。我國(guó)銻礦儲(chǔ)量和產(chǎn)量均居世界**，并大量出口，生產(chǎn)高純度金屬銻(含銻)及質(zhì)量特級(jí)銻白，表率著世界銻業(yè)先進(jìn)生產(chǎn)水平。元素用途銻是電和熱的不良導(dǎo)體，在常溫下不易氧化，有抗腐蝕性能。因此，青海5N5銻粉廢料回收，青海5N5銻粉廢料回收，銻在合金中的主要作用是增加硬度，常被稱為金屬或合金的硬化劑。在金屬中加入比例不等的銻后，金屬的硬度就會(huì)加大，可以用來(lái)制造軍火。銻及銻化合物首先使用于耐磨合金、印刷鉛字合金及軍火工業(yè)，是重要的戰(zhàn)略物資。銻可用作PET生產(chǎn)中的縮聚催化劑。含銻合金及化合物則用途十分廣，銻化物可阻燃，所以常應(yīng)用在各式塑料和防火材料中，青海5N5銻粉廢料回收。含銻、鉛的合金耐腐蝕。鎘化合物含量限制在1到5微克/
