錳 更多供應(yīng)商 7439-96-5 錳 價格

性狀
淺灰色金屬，性脆。相對密度7.20。熔點(diǎn)(1244±3)℃。沸點(diǎn)1962℃。溶于稀酸，在水中錳與水反應(yīng)?？膳c鹵素、硫、磷、碳、硅作用。熔煉時錳蒸氣與空氣中的氧形成氧化物。有立方體和四角形兩種形式，并具有復(fù)雜的晶體結(jié)構(gòu)。電解金屬錳一般含錳99.7％以上，純電解錳不能加工，加入1％的鎳后變?yōu)榭慑懞辖稹?/td>
所屬類別
無機(jī)化工產(chǎn)品: 無機(jī)鹽: Ck錳鹽
用途與作用
在鋼鐵工業(yè)中主要用于鋼的脫硫和脫氧；也用作為合金的添加料，以提高鋼的強(qiáng)度、硬度、彈性極限、耐磨性和耐腐蝕性等；在高合金鋼中，還用作奧氏體化合元素，用于煉制不銹鋼、特殊合金鋼、不銹鋼焊條等。此外，還用于有色金屬、化工、醫(yī)藥、食品、分析和科研等方面。
合成工藝與制法
碳酸錳法將碳酸錳礦和電解過程中產(chǎn)生的陽極液其成分H2SO435～40g/L、(NH4)2SO4 120～140 g/L、Mnl6～18 g/L，經(jīng)漿化后用硫酸浸出，在固液比1：(8～10)，溫度80～95℃，經(jīng)4～8h，浸出終點(diǎn)Ph3.5，浸出液經(jīng)加入二氧化錳礦粉作氧化劑，再加液氨中和Ph值到7～7.2。粗濾除渣，濾液加乙硫氮除重金屬，經(jīng)過濾得到可供電解新液，送入電解槽電解，陽極板采用銀、錫、銻、鉛合金，陽極采用不銹鋼板，經(jīng)24h電解，使電解錳沉積厚度達(dá)1.5～2.0 mm后，定期取下陰極板，經(jīng)鈍化、熱水沖洗、烘干、剝離、包裝即為電解錳產(chǎn)品。其主要反應(yīng)如下：
MnCO3+H2SO4→MnSO4+H2O+CO2↑
MnSO4+H2O[電解]→Mn↓+H2SO4+0.5O2↑
二氧化錳法將軟錳礦與煤粉按一定比例混合，經(jīng)還原焙燒得一氧化錳，再用硫酸酸解，液氨中和，粗濾除雜質(zhì)，濾液經(jīng)加入乙硫氮進(jìn)一步除去重金屬，精濾后配成電解液，經(jīng)電解得沉積于陰極板的金屬錳，再將陰極板取出經(jīng)鈍化、熱水洗、烘干、剝錳，得到金屬錳。其反應(yīng)式如下：
2MnO2+C→2MnO+CO2↑
MnO+H2SO4→MnSO4+H2O
MnSO4+H2O[電解]→Mn↓+H2SO4+0.5O2↑
