Abstract
Glass/ceramic composites prepared from basalt raw material after its modification, as a glass source, with spinel ceramic were studied. Three batches of these composites, with different amounts of glass and ceramic, were sintered between 900 and 1300°C. Qualitative phase composition by X-ray, microstructure and dielectric constant were examined. The results show that sintering of pyroxenic-basalt based glass with spinel leads to crystallization of augite solid solution (augite ss) and spinel. The effect of glass addition on lowering the porosity has been recognized. By increasing the glass amount, the pores begin to vanish, which consequently lowers the dielectric constant of the composite.
