ABSTRACT:
A glass composition consisting essentially by mol percent of about 55<SiO2<75; 5<BaO<30; and 2 <MgO<22 for use as a matrix of composite materials. A method of making a glass matrix-ceramic particulate composition useful for sealing electrochemical structures, such as solid oxide fuel cells is also disclosed. Method steps include the admixture of finely divided Mg2SiO4particulates with the matrix glass, to reach an overall composition by mol percent of about 55<SiO2<65; 5<BaO<15; and 25<MgO<35.
