化学共沉淀法制备纳米级CoTiO3粉末

传统制备ＣｏＴｉＯ３的高温煅烧法具能耗高，颗粒长大得不到纳米级粉体的缺点，采用化学共沉淀法制备出的纳米级ＣｏＴｉＯ３粉末，粒径最小２５ｎｍ并可随退火温度不同得到相应的值。这种制备纳米级ＣｏＴｉＯ３粉体的方法在国内外未见报道。

Preparing Nano CoTiO 3 Powder by Coprecipitation

Conventionally, CoTiO 3 was prepared by high temperature calcination, which brings forth powder of large grain size at the cost of high energy consumption. The authors adopt the method of chemical coprecipitation to prepare nanometre sized CoTiO 3 powder.The powder of 25 nm as minimum grain size has been obtained; and along with the variation of annealing temperature, the powder of varying grain size can be obtained correspondingly. The present work is creative; no precedent has been found in the reports at home and abroad.
