Abstract

Firing of most of the ceramics is carried out conventionally by indirect heating in furnaces. In this case, a significant temperature gradient develops between the surface and the interior layers of the products. In order to avoid this undesirable effect, heating is carried out maintaining low heating rates which invariably leads to an increased duration of the process. The sintering technique using electron-beam heating does not suffer from this short-coming. Heating is carried out by the energy dissipation of the high-energy electrons during the passage through the specimen. This ensures simultaneous heating of the entire volume of the exposed specimen. The aim of this study was to explore the possibility of accelerating the sintering process of the diopside ceramics using electron-beam heating. Experimental results indicate that by using an electron beam, it is possible to decrease the duration of the technological process and the power consumption significantly. The obtained ceramic has high levels of electrophysical properties and can be used as an electrical insulating material.
