Abstract
The densification of alumina to nearly full density continuous hot pressing is described. The influence of the atmosphere on hot pressing is discussed as well as the influence of the process parameters temperature, pressure and transit rate. The microstructure of hot-pressed alumina is examined and compared with that of normally sintered alumina. X-ray diffraction is applied to investigate a possible crystallographic texture of the grains in hot-pressed alumina. The optical properties of the material are treated in a second paper.
