The firing preparations in liquid or paste form are widely used in electrical and electronic engineering and especially in the thick-film technology ''<xr id="tab:Liquid Silver Preparations for Firing Application (ARGONOR)"/> (Table 8.2)''. The precious metal filler material is mostly pure silver because of its high electrical conductivity. During firing in an oxidizing atmosphere at temperatures between 400 and 850°C a well adhering and highly conductive surface layer is formed.
