The effect of presynthesized powder additives in combined synthesis and sintering of SrZrO3 ceramics

It was shown that the addition to the initial mixture of SrCO ₃ and ZrO ₂ , taken in a stoichiometric ratio to obtain SrZrO ₃ , of a pre-synthesized powder resulted in combining synthesis with sintering of denser ceramics than without addition. The reasons are a decrease in the degree of nonequilibrium of the workpiece compaction process due to a slight increase in friction between particles and a decrease in the likelihood of local compaction. The influence of an increase in internal friction at the bifurcation point is comparable to the influence of external disturbances and internal fluctuations (noise), which leads to instability of the results.
