    Isothermal dilatometric study of sintering in electroceramics

  • Original language description

    Solid-state sintering was studied in ceramic samples by dilatometric measurements. The samples were preheated at 490 °C for 24 hrs to reach a complete transformation of kaolinite into metakaolinite because dehydroxylation and the solid-state sintering run simultaneously. The samples were studied in an isothermal regime at the temperatures 500, 600, 700, 800, 900, 1000 and 1050 °C when no liquid phase is created. The relative expansion was measured for a period of 8 hrs. For the temperatures below 800 °Conly a small contraction (0.15 - 0.20 %) was observed and after 4 hrs the samples became stabilized. For the temperatures above 1000 °C the contraction continued all the time and reached 2.5 %. We also determine which diffusion mechanism is dominant forthe sintering process at a given temperature
