Title: MONOLITHIC BASE MATERIAL AND PRODUCTION METHOD THEREFOR
Abstract:
A monolithic base material (10) that: comprises alumina particles as an aggregate and an oxide phase as a binder; and is an alumina porous body having fine holes. The alumina particles include alumina microparticles having a particle diameter of 0.5-5 µm and coarse alumina particles having a particle diameter of over 5 µm. The number of alumina microparticles contained in the oxide phase is at least 50% of the total number of alumina microparticles and course alumina particles.
