氧化(hua)(hua)(hua)鎂是(shi)堿(jian)性氧化(hua)(hua)(hua)物(wu),具有(you)堿(jian)性氧化(hua)(hua)(hua)物(wu)的通(tong)性,屬(shu)于膠凝材料。白色粉末(淡黃色為氮化(hua)(hua)(hua)鎂),無臭、無味、無毒(du),是(shi)典型的堿(jian)土(tu)金屬(shu)氧化(hua)(hua)(hua)物(wu)


重(zhong)燒(shao)(shao)(shao)鎂砂是(shi)指菱(ling)鎂礦(kuang)在1800℃煅(duan)燒(shao)(shao)(shao)時,二氧(yang)(yang)化(hua)碳完(wan)全逸(yi)出,氧(yang)(yang)化(hua)鎂形成(cheng)(cheng)方鎂石(shi)致密塊體,稱重(zhong)燒(shao)(shao)(shao)鎂(又稱燒(shao)(shao)(shao)結鎂砂),這種重(zhong)燒(shao)(shao)(shao)鎂具有(you)很高(gao)的耐火度。其主要成(cheng)(cheng)分為氧(yang)(yang)化(hua)鎂,選(xuan)(xuan)用天然(ran)特級菱(ling)鎂礦(kuang)石(shi)經浮選(xuan)(xuan)提純、輕(qing)燒(shao)(shao)(shao)、細磨、高(gao)壓壓球(qiu)、超高(gao)溫油豎窯煅(duan)燒(shao)(shao)(shao)而成(cheng)(cheng)。 


氧化鎂(mei)是(shi)堿性氧化物(wu),具(ju)有(you)堿性氧化物(wu)的通性,屬于膠凝材料。白(bai)色(se)粉末(淡黃(huang)色(se)為(wei)氮化鎂(mei)),無臭、無味、無毒,是(shi)典型(xing)的堿土金屬氧化物(wu)
