摘要：

The two-step sintering processing of AgSnO2 electric contact materials was studied. By the discussion for the effect of pre-sintering temperature, pre-sintering time and heating rate on the properties of AgSnO2 electric contact materials, we confirm that the optimal pre-sintering temperature and pre-sintering time are 700 degrees C for 0.5 h and the best heating rate are 15 K/min before pre-sintering and 3 K/min after pre-sintering. The comparative study on properties and microstructures of AgSnO2 electric contact materials prepared by the two-step sintering process and the traditional one-step sintering process was carried out. The results indicate that two-step sintering process increases the sintering activity of AgSnO2 powder and promotes its densification in the high-temperature-sintering stage, which eventually improves the microstructure and performance of AgSnO2 electric contact materials.
