| 摘 要： | 为克服传统固相法和液相法制粉的缺点,本文以工业级碱式碳酸镁和钛白粉为原料,采用液-固凝胶合成技术,并首次使用快速煅烧工艺制得高性能MgTiO3粉体。研究发现,1100℃×4h制备的MgTiO3粉体形状规则,且分布均匀,没有发现大的团聚体存在,d50在0.82μm左右,比表面积为2.38m2/g,MgTiO3相含量可达98%以上,酸可溶物小于1%,较适合作为涂料用填料材料。

| Abstract: | For overcoming some disadvantages of peeparing powders by traditional solid-state reactions and liquid-state reactions,the high performance MgTiO3 powder was synthesized using industrial 4MgCO3·Mg(OH)2·6H2O and TiO2 raw materials by gel-casting technique.MgTiO3 powder was first calcined quickly to 1 100 ℃ with holding 4 hours.The results showed that MgTiO3 powder had regular shape,uniform distribution,no great aggregations with d50 of 0.82 μm and BET of 2.38m2/g.MgTiO3 phase exceed 98% and acid solubility is less than 1%.This MgTiO3 powder was suit to filling materials for some coating. |
