There are disclosed a sintered body of ceramics, comprising 0.1 to 10% by weight of Y2O3; 0.1 to 10% by weight of Al2O3; 0.1 to 10% by weight of AlN; 0.1 to 5% by weight of at least one oxide selected from the group consisting of Li2O, BeO, CaO, V2O5, MnO2, MoO3 and WO3 or a combination of at least
There are disclosed a sintered body of ceramics, comprising 0.1 to 10% by weight of Y2O3; 0.1 to 10% by weight of Al2O3; 0.1 to 10% by weight of AlN; 0.1 to 5% by weight of at least one oxide selected from the group consisting of Li2O, BeO, CaO, V2O5, MnO2, MoO3 and WO3 or a combination of at least one of these oxides with at least one oxide selected from the group consisting of B2O3MgO, TiO2, Cr2O3, CoO, NiO, ZrO2, Nb2O5, HfO2 and Ta2O5; and the balance of Si3N4, and a process for producing a sintered body of ceramics, which comprises molding a powder mixture of the same composition, and sintering the resultant molded compact in a non-oxidative atmosphere. The process of the present invention requires no hot press and therefore very suitable for bulk production.
