鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)為淡藍色的銀(yin)白色重金(jin)(jin)屬(shu)，它有(you)(you)毒性(xing)，是(shi)一(yi)(yi)種(zhong)有(you)(you)延(yan)伸性(xing)的主族金(jin)(jin)屬(shu)。熔(rong)點327.502℃，沸點1740℃，密度(du)11.3437g/cm^3，硬度(du)1.5，質地柔軟，抗張(zhang)強(qiang)度(du)小。鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)是(shi)人(ren)(ren)類***早使用(yong)的金(jin)(jin)屬(shu)之一(yi)(yi)，公元前3000年(nian)，人(ren)(ren)類已會從礦石(shi)中(zhong)熔(rong)煉(lian)鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)。鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)在(zai)地殼中(zhong)的含(han)(han)(han)量為0.0016%。鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)在(zai)自(zi)然(ran)(ran)界中(zhong)有(you)(you)4種(zhong)穩定同位素：鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)204、206、207、208，還有(you)(you)20多種(zhong)放射性(xing)同位素。金(jin)(jin)屬(shu)鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)在(zai)空(kong)氣中(zhong)受到(dao)氧(yang)(yang)、水和二氧(yang)(yang)化碳(tan)作用(yong)，其表面(mian)會很快(kuai)氧(yang)(yang)化生成(cheng)保護薄膜;在(zai)加熱(re)下，鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)能很快(kuai)與(yu)氧(yang)(yang)、硫(liu)、鹵素化合(he);鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)與(yu)冷鹽(yan)酸、冷硫(liu)酸幾乎不起作用(yong)，能與(yu)熱(re)或濃鹽(yan)酸、硫(liu)酸反應(ying);鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)與(yu)稀硝酸反應(ying)，但與(yu)濃硝酸不反應(ying);鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)能緩慢溶于強(qiang)堿性(xing)溶液(ye)。鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)在(zai)地殼中(zhong)含(han)(han)(han)量不大，自(zi)然(ran)(ran)界中(zhong)存在(zai)很少量的天然(ran)(ran)鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)。但由于含(han)(han)(han)鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)礦物聚集，熔(rong)點又很低(di)(328℃)，使鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)在(zai)遠古(gu)時(shi)代(dai)就被人(ren)(ren)們所利用(yong)了。方鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)礦(PbS)直到(dao)今天都是(shi)人(ren)(ren)們提取鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)的主要(yao)來源。遠古(gu)時(shi)代(dai)人(ren)(ren)們偶然(ran)(ran)把方鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)礦投進篝火中(zhong)，它首先(xian)被燒成(cheng)氧(yang)(yang)化物，然(ran)(ran)后受到(dao)碳(tan)的還原，形成(cheng)了金(jin)(jin)屬(shu)鉛(qian)(qian)(qian)(qian)(qian)(qian)磚(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)。

鉛(qian)磚的煉(lian)制(zhi)過(guo)程：1.傳統煉(lian)鉛(qian)法(fa)(fa)燒結(jie)(jie)機和(he)煉(lian)鐵高(gao)爐(lu)是燒結(jie)(jie)機的關(guan)(guan)鍵機器設備(bei)，能(neng)夠各自(zi)進(jin)行氧(yang)化還原反應加工(gong)工(gong)藝，燒結(jie)(jie)全過(guo)程自(zi)身存(cun)有(you)一些缺點：燒結(jie)(jie)全過(guo)程SO2濃(nong)度值低(di)，煙塵轉(zhuan)換(huan)為(wei)(wei)(wei)SO2只(zhi)有(you)超過(guo)90，SO2率低(di)。因為(wei)(wei)(wei)技術性(xing)完善，項目(mu)投資少，鉛(qian)生產制(zhi)造國外依然充分發(fa)揮著關(guan)(guan)鍵功效。2.直接煉(lian)鉛(qian)法(fa)(fa)直接熔煉(lian)鉛(qian)分為(wei)(wei)(wei)閃熔和(he)熔池：典型的閃熔法(fa)(fa)是Kifsett法(fa)(fa)、Otto-Kup法(fa)(fa)、典型熔池為(wei)(wei)(wei)QSL法(fa)(fa)、口(kou)山法(fa)(fa)、ISA爐(lu)、Carl-Do法(fa)(fa)等。產品特(te)(te)點：密度大（達(da)到2.5），性(xing)能(neng)穩(wen)定，結(jie)(jie)實耐用(yong)，抗(kang)壓扛折(zhe)，防火耐潮，耐酸堿腐蝕(shi)，價格便宜，施工(gong)方(fang)便，易于應用(yong)等特(te)(te)點。商(shang)品主要用(yong)途：適用(yong)于充電(dian)電(dian)池、建筑涂料(liao)(liao)、焊材、有(you)機化學鉛(qian)鹽、電(dian)纜(lan)線套(tao)、滾動軸承材料(liao)(liao)、接縫處(chu)材料(liao)(liao)、鉛(qian)合金(jin)和(he)x光線維護材料(liao)(liao)的生產制(zhi)造。
