biomimetic method was used to apply hydroxyapatite (ha) coating onto ti6al4v cylinders. this process is a physicochemical method in which a substrate is soaked in a solution simulating the physiological conditions, for a period of time enough to form a desirable layer of the calcium phosphate on the substrate. in the present study, specimens were soaked in 5, 10 m solutions of naoh at temperatu...

statement of problem: in order to increase the performance of glass ionomer cement, it is reinforced with metal powders, short fibers, bioceramics and other materials. fluoroapatite (ca10 (po4 )6 f2 ) is found in dental enamel and is usually used in dental materials due to its good chemical and physical properties. objectives: in this study, the effects of the addition of synthesized fluoroapat...

in this work, we report high biological performance of silicon substituted nano hydroxyapatite (nha) prepared by immersion of calcium phosphate and sodium silicate as precursors in simulated body fluid (sbf) solution for 24, 36, 48 and 72 hrs at 37°c. characterization and chemical analysis of the synthesized powders were performed by fourier transform, infrared spectroscopy (ft-ir), x-ray powde...

Due to its similarity with biological apatite found in vertebrate hard tissues, calcium hydroxyapatite is one of the most investigated materials bone tissue engineering. As not stoichiometric, ion substituted hydroxyapatites attract much atention since they more closely mimic composition natural bone. Although there are many investigations influence foreign ions on structure and physico-chemica...
