Abstract
The processes of ceramic products via high temperature pressing for high-density transparent ceramic materials production were examined in this paper and their properties were studied. Fine-structural investigations of ceramics, produced under various conditions and process modes, were carried out. Dependences that can purposefully effect to degree of sintering and grain size were revealed. Thus the product with the defined properties can be produced. Ceramic materials, produced by the developed technology, can be applied in the microwaves, for ionizing radiation dosimetry and in the other technics fields.
keywords Hot pressing, beryllium oxide, vacuum tightness, energy output windows, integrated circuit substrate, ceramic, powder.
