摘 要: 將Sn和In先熔煉成合金，然后通過氣霧噴粉工藝，由高壓富氧氣體使合金熔體霧化成微細(xì)的金屬霧滴，并隨即在燃燒道中直接氧化燃燒而生成SnO2/In2O3納米級復(fù)合的陶瓷粉末，其粒度≤25nm。

Abstract:After Sn and In being smelted an alloy, the superheated alloy is atomized into fine melted droplets by a nozzle, and the oxy-burning reaction occurs in burning tower immediately. Because oxygen content in the atomizing gas is very high, oxy-burning reaction is very intense, so the size of SnO2/In2O3 nano-size powder prepared is less than 25nm.
Key words: atomizing-combustion nano-sized powder SnO2 In2O3
