摘要
在多组份超细催化剂制备中，如果超细粒子在焙烧时发生固相反应，则难以得到新的晶相的超细粒子．以激光化学法制备的ＦＣ２Ｏ３超细粒子为主要原料．采用表面活性剂分散和保护的方法，制备了数种多组份超细催化剂，并对制备方法及表面活性剂的作用进行了讨论．
If the solid-phase reaction of the raw ultrafine particles has been taken place during roasting for the preparation of multiple-component ultrafine catalyst, it is difficult to obtain new phase of ultlatine particles. In this paper, the multiple-component ultrafine catalyst have been prepared with surfactants for protection and dispersion to produce ultrafine particles of Fe2O3 (10￣20 nm) by laser-chemistry method. The preparation method and the function of the surfactants have been studied in detail.
