摘　　要：用化学沉淀法、十二烷基硫酸钠(简称SDS)微乳液介质法分别合成了SnO2微粉， 并将其制备成旁热式气敏元件，进行气敏性能测定.结果表明，用SDS微乳液合成的SnO２ 纳米微粉，可以提高SnO２气敏元件对某种气体的灵敏度和选择性，对SnO２气体传感器 的开发具有一定的价值.Tin oxide powder was made by chemical precipitation and SDS microemulsion respec tively. Side-heated type gas sesors were fabricated with these powder, their ga s sensing properties were measured too. It can be known from expreimental result s that the SnO2 nanosized powder prepared by SDS microemulsion can increase th e gas sensitivity and selectivity of SnO2 gas sensor.This method of preparing gas sensing material has some value in developement of gas sensor.
