ABSTRACT:
The lifetime of multiple capillary nozzle assemblies embedded in a glass mass, of a multiple nozzle ink-jet printer, can be increased and the thermal and mechanical compatibility of the resulting package enhanced by fabrication of the nozzles from glass compositions comprised of SiO.sub.2, ZrO.sub.2, Na.sub.2 O, K.sub.2 O and MgO. Inclusion of ZrO.sub.2 as well as minor amounts of BaO, MgO, CaO, and Al.sub.2 O.sub.3 enhances the alkali resistance of the glass nozzles. Also, the high SiO.sub.2 content of the glasses combined with the presence of ZrO.sub.2, MgO, CaO, and Al.sub.2 O.sub.3 imparts an acid resistance to the nozzles.
