PURPOSE:To enable formation of complex sintered material having high strength and electrical insulating properties, by forming a sintered material wherein lamellar alumina particles and partially stabilized zirconia particles in a specific ratio are uniformly dispersed into a base having a specific particle size, consisting of alumina particles. CONSTITUTION:The complex sintered material has the following structure. Namely, 2-30vol.% lamellar alumina particles (3) having 3-25mum average particle diameter and 3-20 aspect ratio and 3-50vol.% partially stabilized zirconia particles (2) having 0.1-2.0mum average particle diameter [with the proviso that sum of (2)+(3) is <=55vol.%] are uniformly dispersed into a base (1) substantially consisting of alumina particles having <=5mum average particle diameter. |
