Numerical bremsstrahlung cross sections for different ceramic compounds like Alumina (Al2O3), beryllia (BeO), ceria (CeO), Zirconia (ZrO2) were calculated by using Zmod of metallic compounds at different incident electron energies (10 keV,20 keV and 30 keV) in the photon energy regions of energy (1-10 keV,1-20 keV and 1-30 keV). The cross sections were calculated by using Elwert corrected (non ...

Zirconia–alumina composites couple the high toughness of zirconia with peculiar properties alumina, i.e., hardness, wear, and chemical resistance, so they are considered promising materials for orthopedic dental implants. The design performance needs to consider different aspects, such as type amount stabilizer sintering process, that affect mechanics toughening and, hence, mechanical propertie...

Ultrafast laser processing of zirconia/alumina nanocomposite ceramics, the current gold standard material for ceramic bearing components in orthopedics, was investigated. Instead considering substrate as a homogeneous material, commonly assumed micromachining, damage behavior different phases around ablation threshold upon ultrafast irradiation Under appropriate experimental conditions, zirconi...

objectives: this study aimed to evaluate the effect of different ceramic surface treatments after machining grinding on the biaxial flexural strength (bfs) of machinable dental ceramics with different crystalline phases. materials and methods: disk-shape specimens (10mm in diameter and 1.3mm in thickness) of machinable ceramic cores (two silica-based and one zirconia-based ceramics) were prepar...
