摘 要: | 采用前驱物热解的方法制备了几种具有不同形貌的MgO纳米粉体材料。首先,以无水MgSO4、尿素、氨水、NaOH为原料,分别利用直接沉淀法和均匀沉淀法,在100℃液相反应中获得Mg5(CO3)4(OH)2·4H2O和Mg(OH)2纳米结构材料。然后,以已制备的Mg5(CO3)4(OH)2·4H2O和Mg(OH)2作为前驱物,通过在500℃空气中热解获得了一系列不同形貌的MgO纳米粉体材料。 |
关 键 词: | 材料合成与加工;MgO;Mg(OH)2;纳米材料;沉淀法 |

Abstract: | This paper developed a precursor pyrolysis method to synthesize MgO nanomaterials. Firstly, the precursors of Mg5(CO3)4(OH)2·4H2O and Mg(OH)2 were synthesized via direct and uniform precipitation routes at 100℃, with anhydrous magnesium sulfate, urea, ammonia, sodium hydroxide as raw materials, respectively. Subsequently,a series of MgO nanopowder materials were prepared by the pyrolysis of the as-obtained precursors Mg5(CO3)4(OH)2·4H2O and Mg(OH)2. |
