Chlorination of Ball-milled Zirconia
The effects of mechanochemical treatment of monoclinic zirconia in high energy planetary ball mill on its phase transformation were investigated. The mechanical treatment in ball mill reduces the grain size, increases microstrain, and causes phase ...

Effect of Crystalline Size on the Structure of Copper Doped Zirconia Nanopaticles Synthesized via Sol-Gel [PDF]
The stabilized zirconia with different Cu contents synthesized via sol- gel method. The samples were prepared by hydrolysis and condensation of orgnomatelic sol. After that the result gels were dried at 80 °C and then calcined at various temperatures.

Phase diagrams of zirconium dioxide systems with yttrium and scandium oxides
The literature data on the study of phase equilibria in systems zirconia with yttria and scandia are analysed. Possible schemes of low-temperature phase equilibria in ZrO2-Y2O3 and ZrO2-Sc2O3 systems are presented taking into account the third law of ...

Electrochemical blackening of yttria-stabilized zirconia : morphological instability of the moving reaction front [PDF]
Electrochemical reduction was performed on both polycrystals of calcia-stabilized zirconia (CSY) and single crystals of yttria-stabilized zirconia (YSZ) at 500°C. A glass-encapsulation was used to prevent access of molecular oxygen from the gas phase and
