SHS of Y2Ti2O7-based mineral-like ceramics: Influence of green density

Explored was the influence of compacting pressure ( P ) and green density (ρ) on the properties of Zr-doped mineral-like pyrochlore ceramics Y 2 (Ti 1 – x Zr x ) 2 O 7 ( x ≤ 0.3) prepared by SHS method. The optimal ρ values that provide minimal porosity and maximal mechanical strength of synthesized...

Zusammenfassung:Explored was the influence of compacting pressure ( P ) and green density (ρ) on the properties of Zr-doped mineral-like pyrochlore ceramics Y 2 (Ti 1 – x Zr x ) 2 O 7 ( x ≤ 0.3) prepared by SHS method. The optimal ρ values that provide minimal porosity and maximal mechanical strength of synthesized ceramics were found. An increase in ρ was found to decrease combustion temperature and increase pyrochlore lattice parameter a . Green density was also found to affect phase composition of the SHS-produced ceramics under study.
