摘要: Abstract The preparation of screen-printing inks with a high solids load was studied for the development thick-film varistors. A can ensure higher green density films enhanced densification and microstructure in order, to obtain good current–voltage ( I–U ) characteristics varistor, even after short firing times at temperatures below 1000 °C. 50, 60 70 wt.% enabled varistors on an alumina substrate homogenous microstructure, uniformly distributed Bi 2 O 3 -rich phase varistor film-electrode contact 900 °C 15 min. However, porosity gradually decreased increasing film prepared from ink highest had minimal improved comparison other samples.
