Abstract

Glass-ceramics which consist of tantalum pentoxide (Ta2O5), hexacelsian (BaO·Al2O3· 2SiO2), and aluminium tantalate (Al2O3·Ta2O3) are described. These glass-ceramics can form refractory composites up to 1400° C with molybdenum metal. The glass-ceramics and metal have compatible physical and chemical properties which allow close thermal expansion and excellent bonding.
