Single- and multi-component sintering additives for aluminum oxide ceramics are presented. It was determined from the published data that because of their higher melting temperatures and the impossibility of simultaneously influencing a number of properties of the desired material single-component additives are less effective than multi-component additives. Because of synergy multi-component additives makes it possible to simultaneously improve the properties of sintered samples based on aluminum oxide, specifically, greater compaction (porosity about 0.1%) of the samples, sintering temperature reduction to 1400°C, preservation of a fine-crystalline structure (average grain size about 3 μm), higher crack resistance about 5.86 MPa · m1/2, and higher ultimate strength in bending about 600 MPa.
