초록
The purpose of this study is to investigate the electrical properties of thick-film resistor (TFR) prepared from CaO-ZnO-B2O3-Al2O3-SiO2 (CZBAS) glass containing RuO2 particles. RuO2-glass composite powder was made by mixing and melting oxide powders of constituents. For comparison, RuO2 powder was simply mixed with glass powder. RuO2-40wt% glass composite and mixture were dispersed in an organic binder to obtain printable resistor paste and then thick-film was formed by screen printing, followed by sintering at the range between 750 oC and 900 oC for 10 min with a heating rate of 50 oC/min in an ambient atmosphere. RuO2– glass composite sample showed much higher resistance compared to the simple mixed sample. This could be attributed to the difference in conducting mechanism. After sintering at 850 oC, temperature coefficient of resistance of composite sample was lower than that of simple-mixed sample. TFR with dense and homogeneous microstructure could be obtained by using RuO2-glass composite powder.
