但加熱時(shí)能與氧氣反應(yīng)生成三氧化二銻。銻是一種帶有銀色光澤的灰色金屬，其莫氏硬度為3。因此，純銻不能用于制造硬的物件：貴州省曾在1931年發(fā)行銻制的硬幣，但因?yàn)殇R很容易磨損，在流通過(guò)程損失嚴(yán)重。銻在一般條件下不與酸反應(yīng)。銻的同素異形體屬于六方晶系排布狀態(tài)(hexagonalcrystalsystem），有一個(gè)6次對(duì)稱軸或者6次倒轉(zhuǎn)軸，該軸是晶體的直立結(jié)晶軸C軸。另外三個(gè)水平結(jié)晶軸正端互成120夾角。軸角α=β=90，γ=120，軸單位a=b≠c，次性質(zhì)使得用尖銳的器具刮擦它就會(huì)發(fā)生放熱的化學(xué)反應(yīng)，放出白煙并生成金屬銻。如果在研缽中用研杵將它磨碎，就會(huì)發(fā)生劇烈的炸開(kāi)。黑銻是由金屬銻的蒸汽急劇冷卻形成的，它的晶體結(jié)構(gòu)與紅磷和黑砷相同，在氧氣中易被氧化甚至自燃。當(dāng)溫度降到100℃時(shí)，它逐漸轉(zhuǎn)變成穩(wěn)定的晶型。黃銻是很不穩(wěn)定的一種，只能由銻化氫在-90℃下氧化而得。在這種溫度和環(huán)境光線的作用下，亞穩(wěn)態(tài)的同素異形體會(huì)轉(zhuǎn)化成更穩(wěn)定的黑銻。金屬銻的結(jié)構(gòu)為層狀結(jié)構(gòu)（空間群：），而每層都包含相連的褶皺六元環(huán)結(jié)構(gòu)。很近的和次近的銻原子形成變形八面體，在相同雙層中的三個(gè)銻原子比其他三個(gè)相距略近一些。這種距離上的相對(duì)近使得金屬銻的密度達(dá)到g/cm。北京6N銻回收五氧化二銻只能用濃硝酸氧化三價(jià)銻化合物制得。</p><div
