KEY WORDS:

fusion, noble metals, wetting, oxides of bismuth, germanium, silicon, titanium, boron, zinc.

ABSTRACT:

The wetting of Ag, Pt, Pd, Au and Ir by the Bi2O3-GeO2 (SiO2, TiO2, B2O3, ZnO) fusions in dependence on temperature and fusion composition was investigated. The lowest interaction of such melts was demonstrated to occur with iridium.
