The sintering of zircon-based (ZrSiO 4) ceramics prepared from a batch containing ball clay and wollastonite as additives has been studied.

Abstract
The sintering of zircon-based (ZrSiO 4) ceramics prepared from a batch containing ball clay and wollastonite as additives has been studied. Physical properties of extruded and dry pressed specimens fired at 1280 °C are compared with those of extruded test specimens of pure zircon fired at 1600 °C. The sintering aids of zircon determine the formation of a glassy phase in which the zircon is embedded. The partial crystallization of such a glassy phase, performed with a nucleation and crystal growth process, enhances the strength of the fired zircon-based bodies. These materials have been utilized as a grinding medium for industrial frits and glazes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
