- Abstract
The paper considers a new technology for obtaining ceramic materials based on slawsonite, which is a two-stage one. The first stage is the synthesis of the slawsonite phase and the grinding of the synthesized material. The second stage is the formation of raw material by the method of slip casting into plaster molds and the subsequent firing of the products. The effect of temperature-time regimes on the properties of slawsonite ceramics has been studied. Changeable technological parameters: firing temperature of products – 1,350 °C and 1,400 °C, exposure at maximum temperature – 2 and 4 hours. The morphology and phase features of the samples were studied by X-ray phase analysis and scanning electron microscopy. Regularities of changes in physical and mechanical properties depending on the temperature and duration of firing of experimental ceramics are established. It is proved that with an increase in the duration of firing of samples, the values of water absorption and open porosity decrease and the density of slawsonite ceramics increases. The mechanical and dielectric properties of experimental ceramics are experimentally studied, the values of which are in the ranges ε = 5.8 - 13.2; σ = 140 - 390 MPa.
