| 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，进行了气敏性能测定。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。 |

Study on SnO2 fine powder made by SDS microemulsion |
|
| Abstract: | 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. |
| Keywords: | gas sensitive devices tin oxides sensitivity microemulsion |
