Conclusions
X-ray and electron-microscopic methods were used to study the composition and structure of specimens in the ZrO2-CaO system (12–25% CaO) after prolonged firing at 1100–1420°C.
We established the presence in the aging products of the ordered phasesϕ 1 (CaZr4O9),ϕ (Ca2Zr7O16), andϕ 2 (Ca6Zr19O44).
