ABSTRACT:
A component of aluminum nitride metallized with a metallizing paste containing: (i) a pulverulent glass of the MnO--Al.sub.2 O.sub.3 --SiO.sub.2 system as an adhesion promotor having a mean particle size of 2-15 .mu.m; (ii) a refractory metal powder having a mean particle size of 1-4 .mu.m; and (iii) an organic resin dissolved in a suitable solvent and/or a screen printing oil is disclosed. The metallizing paste preferably has a viscosity of 50-100 Pa.multidot.s when applied by screen printing, and a viscosity of <5 Pa.multidot.s when applied by dipping. The component of aluminum nitride metallized with the metallizing paste has at least one metal layer deposited on the metallizing paste, and the at least one metal layer applied has a bonding strength given by mean pull-off values of .gtoreq.3.5 kN/cm.sup.2.
