PURPOSE:To enable to readily sinter a blend low sintering temperature and wide sintering temperature range, by blending a sintering auxiliary of a specific compound into a complex ceramic raw material containing MgO, Al2O3 and SiO2 as main components. CONSTITUTION:The titled sintered compact obtained by blending a compound capable of providing lanthanum oxide and zirconium oxide or lanthanum zirconate after burning as a sintering auxiliary to a complex ceramic raw material consisting of MgO, Al2O3 and SiO2 constituted as main components and burning the blend. The aimed sintered compact is extremely readily obtained at low sintering temperature and wide sintering temperature range by blend of the above-mentioned sintering auxiliary. |
