The development of crystalline phases (mullite, pseudo-cubic zirconium dioxide, and zircon), microstructure, linear shrinkage, apparent density, and compressive strength of ceramic samples obtained from powders after grinding and synthesis in a reactor using illite clay as a binding agent in depending on the temperature regime during spark plasma sintering.
The results of X-ray phase analysis indicate an intensive development of the mullite phase and pseudocubic zirconia in all samples with an increase in the sintering temperature, and the formation of a dense microstructure of the samples is also observed. Additionally, the linear shrinkage of the samples increases with an increase in the sintering temperature, as well as the apparent density and compressive strength of the samples with an increase in the grinding time up to 24 h and the introduction of clay into the samples, showing, respectively, the maximum values ??of 3.45 g / cm 3 and 252.0 MPa.
