ZIRCONIUM DIOXIDE (zirconia) has three allotropes: monoclinic, tetragonal and cubic. The transition between the first two involves a large volume expansion which prevents the refractory properties of pure zirconia being used in structural ceramics. The disruptive phase transformation can be suppressed by total stabilisation in the cubic form, but it is generally recognised that the most useful mechanical properties are obtained in multiphase material known as partially-stabilised zirconia (PSZ…

Zirconium oxide is one of the most promising ceramic materials as it finds applications in several high-level technological fields, ranging from biomedicine to sensing. Zirconium oxide is

Bonding to Zirconia (A Systematic Review)

There is a wealth of information in the scientific literature regarding the use of zirconia (ZrO2) in dental applications, which potentially provide better fracture resistance and long-term viability when compared to porcelain and other inorganic, non-metallic alternatives.

Low-temperature degradation resistance and plastic deformation of ATZ ceramics stabilized by CaO

In this work, the phase composition (relative fractions of monoclinic m-ZrO2, tetragonal t-ZrO2, and cubic c-ZrO2 phases) and mechanical properties (hardness, fracture toughness, compressive

Effect of calcia co-doping on ceria-stabilized zirconia

Synthesis of Coloured Dental Zirconia Ceramics and their Mechanical Behaviors

The effects of Pr6O11 and Er2O3 dopants on microstructure and mechanical properties of zirconia ceramics were investigated. The phase composition and microstructure analysis indicate that samples are

Microstructure and Mechanical Properties of 3YSZ Ceramics Rainforced with Al2O3 Particles

The effect of Al2O3 addition on microstructure and mechanical properties of high purity 3 mol% yttria-stabilized zirconia (3YSZ) was investigated. The monoclinic zirconia (m-ZrO2) phase has

Zirconia-Mullite Obtained from Co-Precipitated Zirconia-Mullite Composite Powders by SPS

The co-precipitation method is used to fabricate precursor powder. This powder is densified by means of the spark plasma sintering (SPS) technique at 1500 °C with a holding time of 7 min to prepare

Reinforcement Mechanisms in Yttria-Ceria-Co-Stabilized Zirconia- Alumina-Strontium Hexaaluminate Composite Ceramics

Composite ceramics with 1 mol% yttria and 6 mol% ceria co-stabilized zirconia matrix were reinforced with 10 vol% alumina and 10 vol% in situ-formed strontium hexaaluminate. Samples were shaped by

Theoretical description of zirconia ceramics aging kinetics

An analytical approach for fraction calculation of monoclinic phase on zirconia surface under aging conditions was developed. The approach is based on a model of nucleation and growth of areas which
