Description
技术领域
本发明属于耐火材料技术领域，具体涉及一种高纯度致密镁橄榄石及其制备方法。
背景技术
镁橄榄石为岛状结构硅酸盐，其理论化学式为2MgO·SiO2或Mg2SiO4，是镁质耐火材料中较耐高温的矿物具有熔点高、导热系数低、稳定性好，耐金属熔体和渣侵蚀性能优良，耐碱蒸气侵蚀性能优良，可用于钢包、玻璃窑炉蓄热室材料、电炉出钢口填充料主要原料等，也可用于水泥窑替代部分方镁石—镁铝尖晶石材料，能够降低筒体温度，提高水泥窑热效率，节约能源。天然镁橄榄石与铁橄榄石伴生，杂质含量高、烧失大，Fe2O3及Al2O3等杂质在高温下形成低熔物如钙镁橄榄石、堇青石等，影响材料的高温性能。
中国专利申请CN 103044043 A公开了一种致密镁橄榄石耐火原料及其制备方法，其制备方法为：先将69-85%的滑石粉，10-30%的镁质原料细粉，包含电熔镁砂细粉、烧结镁砂细粉和轻烧氧化镁粉中的一项，0.2-2%的添加剂混合，制得混合料；再外加所述混合料1-10%的结合剂，球磨1-3小时，加入3-10%的水，搅拌10-30分钟，压制的坯体，干燥后在1350-1650℃煅烧1-3小时，制得致密镁橄榄石耐火原料。该方法主要是用滑石和电熔镁砂、烧结镁砂和轻烧氧化镁，并且滑石和镁质原料细粉中Fe2O3、CaO和Al2O3杂质含量分别为小于1.2%和3%，杂质含量较高，易生成堇青石、钙橄榄石、铁橄榄石及玻璃等低温相，影响产品纯度及高温性能。
中国专利申请CN 106187217 A公开了一种镁橄榄石的制备方法，其制备方法为：以高炉渣为原材料，磨成粉末，与铝粉在煅烧炉中煅烧、粉碎，利用磁铁将粉碎的粉末中的铁去除，用盐酸浸泡，过滤，干燥滤渣，与氢氧化钠溶液反应后，除渣，将过滤液浓缩并与氧化镁粉末，凹凸棒土混合，经熔融炭化，静置冷却即可制备镁橄榄石。该方法使用高炉矿渣作为原料，杂质含量高，制作过程使用盐酸、氢氧化钠等强酸强碱，流程多且风险高，合成的镁橄榄石杂质含量高。
中国专利申请CN 104725057 A公开了一种中密度镁橄榄石砂及其制备方法，其制备方法为：取85-93%的菱镁矿尾矿在1200-1350℃下轻烧0.5-5小时，与7-15%的石英粉混合研磨，得到粒径小于0.088mm的轻烧尾矿和石英混合料；再依次外加占上述混合料5-40%的成孔剂，3-12%的结合剂，进行混合、混炼、110-150MPa压强机压、干燥、1650-1720℃焙烧4-9小时制得。菱镁矿尾矿中含有一定量的CaO和Al2O3，在高温合成时与MgO和SiO2反应，分别形成钙橄榄石、堇青石及玻璃相等低温相，影响镁橄榄石纯度及高温性能。
