锰矿石 百度百科
锰矿石性质 编辑播报 锰矿石通常可被酸分解。 常用的酸有盐酸、硝酸—过氧化氢、氢氟酸—硫酸、磷酸—硝酸。 不被酸分解的矿样可用碱性熔剂、酸性熔剂熔融分解。 软锰矿如加热至550～600℃时发生分解，变成β—褐锰矿(Mn2O3)。 大部分的锰矿都含有相当多的水 This stony meteorite was seen to fall, with loud rumblings and explosions, on April 9, 1894, near the town of Fisher, Polk County, Minnesota Residents found fragments of it Dr Bill's MN Geology Snapshots Minnesota Mineral Club

Aug 12, 2019 锰元素在钢中的作用 一、锰对钢的显微组织及热处理的影响 ① 锰是良好的脱氧剂和脱硫剂，工业用钢中均含有一定量的锰。 ② 锰固溶于铁素体和奥氏体中，能扩大奥氏体区，使临界温度升高。 ③ 锰极大降低了钢的马氏体转变温度 (其作用仅次于碳)和钢中相变的速度，提高钢的淬透性，增加残留奥氏体含量。 ④ 使钢的调质组织均匀、细化，避免 Dec 30, 2015 Here are 13 things that make Minnesota truly unique 1 There are 69,200 miles of rivers and streams in Minnesota That's enough to circle the equator 2 3/4 times!
