Abstract
High-temperature synthesis with the use of microwave energy is used to fabricate corundum materials with a relative density of 95 – 99% of the theoretical value from aluminum oxide powders with different grain sizes and prehistory. The microstructure of the materials is composed of grains with a size close to the initial one and closed spherical pores.
