“…The ZTA ceramic composites with 0.5 wt % MgO content exhibited the best attributes, such as a fracture toughness value of 9.14 MPa•m 0.5 and a hardness value of 1591 HV. Similarly, the effect of TiO2 phase composition and mechanical properties of Ca-TZP (calcium stabilized tetragonal zirconia) ceramic have been observed, with fracture toughness values up to 9.1 MPa√m after reinforcement with TiO2 in the range of 0.5-0.65 mol % [192].…”

Toughening of Bioceramic Composites for Bone Regeneration

Bioceramics are widely considered as elective materials for the regeneration of bone tissue, due to their compositional mimicry with bone inorganic components. However, they are intrinsically brittle, which limits their capability to sustain multiple biomechanical loads, especially in the case of load-bearing bone districts. In the last decades, intense research has been dedicated to combining processes to enhance both the strength and toughness of bioceramics, leading to bioceramic composite scaffolds. This review summarizes the recent approaches to this purpose, particularly those addressed to limiting the propagation of cracks to prevent the sudden mechanical failure of bioceramic composites.

“…Nano ZrO 2 powder can be synthesized through various methods like sol-gel, co-precipitation, and hydrothermal synthesis. [17][18][19][20] Zirconium oxide (ZrO 2 ) has been extensively investigated in its tetragonal and cubic phases, particularly for their dielectric properties. [21][22][23] However, the orthorhombic phase, especially in the form of nanorods, remains relatively unexplored.…”

This study reports the synthesis of high dielectric constant zirconia oxide (ZrO2) nanorods (NRs) via a co-precipitation method followed by calcination at 700°C for 2 hours. X-ray diffraction (XRD) confirms a mixed-phase composition of orthorhombic and monoclinic structures, while transmission electron microscopy (TEM) reveals distinct nanorods. Energy dispersive X-ray analysis (EDAX) verifies the elemental composition. Photoluminescence (PL) spectroscopy indicates band gap energy of 1.9 eV, aligning better with orthorhombic zirconia. UV-Vis analysis suggests oxygen vacancy defects potentially influencing the optical properties due to the nanorod morphology. Importantly, dielectric studies show a high dielectric constant of 29 at 1 MHz, which is approximately four times higher than commercially available ZrO2.
