| Abstract: | Zn_2SnO_4 composite oxide which is weak N-type semiconducter with anti-spinel type structure is pre- pared by means of the sintering method (ZnO:SnO_2=2:1,mole ratio).Its gas sensitive properties are notice- able,especially for alcohol gas.The sintered gas sensor has well sensitivity and selectivity.When less oxide impurity(1wt%)was doped,the sensitivity and optimum operating temperature gets better,and the rare- earth oxide is the best. |
