Heading: Science for ceramic production

One- and multicomponent sintering additives for ceramics based on aluminum oxide are presented. It has been established from the literature that the use of one-component additives is less effective than multicomponent, due to their higher melting temperatures and the impossibility of simultaneously influencing a number of properties of the target material. Due to the synergistic effect, the use of multicomponent additives makes it possible to achieve a simultaneous improvement in the properties of sintered samples based on aluminum oxide, in particular, an increase in the degree of compaction (porosity & # 8776; 0.1 & # 37;) of samples, a decrease in the sintering temperature to 1400 & # 176; C, preservation of a fine-crystalline structure (average grain size & # 8776; 3 microns), an increase in the value of crack resistance & # 8776; 5.86 MPa • m1 / 2 and ultimate strength in bending & # 8776; 600 MPa
