Abstract

Thermal expansion of refractory ceramics CaZrO₃, MgAl₂O₄, La₂Zr₂O₇ and YSZ-12 was studied. The samples of the complex oxides were synthesized by solution combustion synthesis with glycine; the fuel:oxidant ratio was varied depending on the character of redox reaction. The linear thermal expansion coefficient (LTEC) of ceramics was measured on the samples with an initial density 23–52%. The maximal sinterability of 89–92% after 6 h annealing at 1550 °С was demonstrated by La₂Zr₂O₇ and YSZ-12, and the minimal values (78–82%) – by CaZrO₃ and MgAl₂O₄. All materials have close LTEC values, from 9.0 to 9.6·10^–6 K^–1.
