Resumo

Formation and sintering of nanostructured Al₂O₃ and boehmite powders prepared by hydrothermal synthesis from aluminum powder are studied. Formation of workpieces (green bodies) is performed by extrusion, static and explosive pressing followed by high-temperature sintering. Use of explosive pressing increases raw material density, reduces the temperature for α-Al₂O₃ formation, activates sintering, and improves ceramic operating properties.
