摘　　要：采用丝网印刷的方式制备平板式氧传感器Pt电极,研究不同种类的有机载体和黏结剂对Pt浆料整体烧结性能的影响。结果表明,采用溶剂、增稠剂、表面活性剂、流变剂和触变剂等多种组分的混合物作为有机载体,选用几种金属氧化物的混合物作为黏结剂,并通过球磨工艺混合粉体颗粒制成的Pt浆料,其高温烧结性能最好。Pt electrode of plate oxygen sensors was prepared by means of screen printing, and the effects of different types of organic vehicle and binder on the sintering performance of Pt slurry were investigated. The results show that, using a mixture of solvent, thickener, surfactant, leveling agent and thixotropic agent as organic vehicle, a mixture of metal oxides as a binder, Pt slurry made from ball-mixed powder particles has the best high-temperature sintering performance.
