Glass-ceramic composites consisting of 10SrO・50ZnO・40P_2O_5 (SZP) glass and Al_2O_3 with various particle sizes and specific surface areas were fabricated for the barrier-rib of plasma display panel. The variations of density, microstructure, bending strength and thermal expansion coefficient with Al_2O_3 contents were studied for SZP/Al_2O_3 composites. The positively or negatively charged surface state of SZP and Al_2O_3 particles was estimated from the pH of the aqueous suspensions prepared using the mixture of SZP glass or Al_2O_3 particles with 10 vol% and distilled water with pH 7 without pH adjustment. The combination of SZP glass and Al_2O_3 raw materials with similar charged surface state provides a dense SZP/Al_2O_3 sintered composite with a relatively-high bending strength and with a homogeneous microstructure.
