Influence of alumina substrates open porosity on calcium phosphates formation produced by the biomimetic method

Impact of ZrO2 Content on the Formation of Sr-Enriched Phosphates in Al2O3/ZrO2 Nanocomposites for Bone Tissue Engineering

“…To enhance the wettability and roughness of the nanocomposites, their surfaces were treated with a 5 mol/L phosphoric acid aqueous solution (H 3 PO 4 ) for four days in a thermostatic bath at 90 • C [18]. Subsequently, the nanocomposites were rinsed with distilled water and dried at room temperature for 72 h. The treatment with H 3 PO 4 can influence both wettability and roughness by activating functional sites that promote the deposition of phosphates [24].…”

“…Calcium phosphates are bioceramics that resemble the inorganic components of bones [20,21]. Calcium phosphate phases exhibit distinct degradation rates and solubility, enabling greater adaptability with the desired application for these materials [22][23][24]. The biological performance of these calcium phosphates phases stems especially from the structural arrangement of the ions of each phase governing the physicochemical properties of the phosphates [21,25].…”

Ceramic Materials for Biomedical Applications: An Overview on Properties and Fabrication Processes

“…In recent decades, bioceramics such as alumina, zirconia, SiAlON, bioglasses, and hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 ) have been studied for dentistry applications. Porcelain, zirconium oxide, and single-crystal sapphire are already being used on a large scale for orthodontic issues [ 88 , 89 , 90 ]. The main disadvantages of modern osteoplastic devices made of bioceramics are the fragile behavior and the low resistance to tensile or bending forces.…”
