<p>This invention is particularly directed to the production of glass-ceramics specifically designed for bonding hard refractory particulate ceramics into dense, mechanically strong composite bodies. The inventive glass-ceramics are crystallized in situ from divalent metal borate glasses. The invention is particularly drawn to composite articles where Al2O3 particles comprise the hard refractory ceramic and the inventive glasses react therewith to form an exceptionally strong bond therebetween accompanied with the development of divalent metal aluminoborate crystals.</p> |
