PURPOSE:To augment the release properties for reducing the dispersion thereof by a method wherein the required parts of ceramic elements are coated with conductive paste and after drying up they are held between ceramic substrates to be baked. CONSTITUTION:The surface of alumina elements 0.4t(mm) thick are printed with an Ag base conductive paste using 200 mesh Tetoron-made screen and the said surface, after dried up at 150 deg.C for 20 minutes, is baked at 620 deg.C for 20 minutes to form Ag electrodes around 10mum thick. The elements 3 formed into electrode are held between magnesia-made ceramic substrate 4 2.0t(mm) thick. Consequently, when the electrode surface are pressed down by the load of the ceramic substrate 4 to form the electrodes 3, the glass frit in the conductive paste is melted down to be made finer. |
