Abstract
In-situ formation of glass-ceramic composites by the Self-propagating High temperature Synthesis (SHS) technique. The reagents used are: TiO.sub.2, B.sub.2 O, Al, Ti, B and MO where MO represents BaO, MgO, CaO and other similar oxides. BaCO.sub.3 may be substituted for BaO. The composition of the reaction products can be adjusted by adjusting the ratios of the reagents. All reagents are in powder form and the reaction can be carried out either in inert atmosphere inside a reaction chamber or in air without a chamber. The materials produced have crystalline TiB.sub.2 particles in a glassy matrix (aluminoborate glass). The TiB.sub.2 particles have a size of about 0.5 .mu.m. Advantages include processing simplicity and cost savings. The glass-ceramic composites produced are electrically conductive and find application where high strength, hardness and electrical conductivity are required.
