地殼中自然存在的純銻很早是由瑞典籍英國(guó)科學(xué)家威廉·亨利·布拉格于1783年記載的。品種樣本采集自瑞典西曼蘭省薩拉市的薩拉銀礦。[5]銻應(yīng)用編輯60%的銻用于生產(chǎn)阻燃劑，而20%的銻用于制造電池中的合金材料、滑動(dòng)軸承和焊接劑。銻阻燃劑銻的很主要用途是它的氧化物三氧化二銻用于制造耐火材料。除了含鹵素的聚合物阻燃劑以外，它幾乎總是與鹵化物阻燃劑一起使用。三氧化二銻形成銻的鹵化物的過程可以減緩燃燒，即為它具有阻燃效應(yīng)的原因。這些化合物與氫原子、氧原子和羥基自由基反應(yīng)，很終使火熄滅。商業(yè)中這些阻燃劑應(yīng)用于兒童服裝、玩具、飛機(jī)和汽車座套。它也用于玻璃纖維復(fù)合材料（俗稱玻璃鋼）工業(yè)中聚酯樹脂的添加劑，例如輕型飛機(jī)的發(fā)動(dòng)機(jī)蓋。樹脂遇火燃燒但火被撲滅后它的燃燒就會(huì)自行停止。[12]銻合金銻能與鉛形成用途廣的合金，這種合金硬度與機(jī)械強(qiáng)度相比銻都有所提高。大部分使用鉛的場(chǎng)合都加入數(shù)量不等的銻來制成合金。在鉛酸電池中，這種添加劑改變電極性質(zhì)，并能減少放電時(shí)副產(chǎn)物氫氣的生成。銻也用于減摩合金（例如巴比特合金），道具、鉛彈、網(wǎng)線外套、鉛字合金（例如Linotype排字機(jī)）、焊料。哈爾濱5N銻粉加工</p><p
