低温燃烧法制备纳米稀土氧化物

低温燃烧合成（LCS）是一种制备材料的新方法,近年来得到广泛研究并应用。它是一种剧烈的氧化还原反应,氧化剂常用硝酸盐或高氯酸盐,还原剂常用有机物。LCS点火温度低（300～500℃）,燃烧火焰温度较低,能简便、快捷地生成氧化物或复合氧化物超细粉体,在一定程度上,有效地克服了SHS工艺可控性较差、能耗高、合成的粉体粒度较粗等不足.

Preparation of Low-temperature Combustion of Nano-rare Earth Oxides

In recent years,Low-temperature combustion synthesis（LCS） have been studied and applied extensively which is a new method for preparation of materials.It is a violent oxidation-reduction reaction.Oxidant commonly used nitrate or high chlorine salts,reducing agent commonly used organic materials.LCS ignition temperature is low（300 ~ 500 ℃）,oxide or complex oxide ultra-fine powder can be obtained conveniently and quickly with low flame temperature.To a certain extent,it overcomes the poor control of the SHS Process,high energy consumption and sustain of the synthesis of coarse particle.
