摘要:
研究了碳酸氢铵和硝酸铝在添加剂氟化铵作用下沉淀法合成片状氧化铝粉体, 讨论了片状氧化铝粉
体的形成机理.通过XRD, SEM 对产物进行表征.结果表明氟化铵有效控制了氧化铝颗粒的大小和形貌, 改
善了氧化铝的结晶.适量加入氟化铵可以获得分布均匀、分散性良好, 粒径3-8 μm , 厚度0 .2 -0 .3 μm 的正
六边形片状氧化铝粉体.
Abstract:
The thesis discusses the formation of flaky alumina powder and concludes a precipitatio n method of sy nthe sizing
flaky alumina pow der , using aluminum nitra te and ammonium bicar bo na te , with small-amount of ammonium fluo ride as
additiv e .The mo rpho lo gy , pa rticle size and phase compo sitio n of aluminium o xide powder we re analyzed by SEM and
XRD.It is fo und that the size and mo rpho lo gy o f Al2O3 par ticles can be effectively co ntro lled by ammo nium fluo ride .The
cry stallization of plate-like α-Al2O3 is improv ed by the additiv es.With ammonium fluo ride , he xag onal lamellate α-Al2O3
powder with pe rfect mor pholog y , smo oth surface , g ood disper sion proper ty , and pa rticle size of 3 ~ 8μm , thickness of about
0 .2-0 .3μm can be prepa red.
