【 摘 要 】

The paper studies the prospects of spark plasma sintering of aluminum oxynitride, determines the optimum modes and parameters of compacting. Optimum modes of preparing a powder mixture for sintering are determined. The structure and properties of sintered samples are studied. The factors affecting the transparency of the finished products are ascertained, and the ways that allow obtaining a high light transmittance are identified.
