摘要
研究了纳米氧化物掺杂对Ag/SnO2触头材料物理性能的影响。采用溶胶-凝胶法制备SnO2与各种掺杂氧化物(包括TiO2、ZnO、Sb2O3、CuO)的混合粉末。粉末的XRD、TEM表明,所得粉末为纳米级,且掺杂物离子能很好地进入到SnO2的晶格中;粉末的密度,电导率等测试表明SnO2的物理性能有了明显改善。
In this paper the influence of adding nanometer powder of metal oxide in contact material has been researched. The composite nanometer powder of tin oxide and other metal oxide which include TiO2, ZnO, Sb2O3 and CuO has been made by sol-gel method. The powder is nanometer powder which has been testified by the method of XRD and TEM, and it also testified that the ion of the adding oxide can perfectly dope into the crystal lattice of tin oxide. Through various physical performance（ eg： density. conductivity） test, it has been proved that the performance of tin oxide especially the electronic performance is distinctly improved （eg：the electric conductivity of Ti nano doped SnO2 could increase 10000 times） . It has great important significance to make new-type Ag/SnO2 contact material.
