Elaboration and Characterization of Alumina-Tricalcium Phosphate Composites
The effect of -tricalcium phosphate additive on the alumina matrix was investigated. The sintering behaviour of the alumina tricalcium phosphate composites was characterized by using magic angle spinning nuclear magnetic resonance, X-ray diffraction, dilatometry, differential thermal analysis and scanning electron microscopy analysis. The mechanical properties of composites have been investiga...
متن کاملControl of -Tricalcium Phosphate Formation in Macroporous Phosphate Glass-Ceramic Composites
A macroporous phosphate invert glass-ceramic (PIGC) was derived from the mother glass with a composition of 60CaO-30P2O5-3TiO27Na2O in mol%. The mother glass powders were coated on a polymer sponge skeleton and subsequently sintered at 850 C for 1 h through burning off the sponge, resulting in the preparation of macroporous PIGC. The resulting macroporous PIGC consists predominantly of tricalci...
متن کاملCALCIUM PHOSPHATE CEMENT: STUDY OF (BETA-TRICALCIUM PHOSPHATE, DICALCIUM PHOSPHATE AND CALCIUM CARBONATE SYSTEM
Calcium phosphate cements (CPCs), using B-tricalcium phosphate (ß-TCP, Ca3 (P04)2), dicalcium phosphate (DCP, CaHP04), calcium carbonate (Ca CO3), and hydroxylapatite (HAp, Ca10(P04)6(OH)2) as powder cement and disodium hydrogen phosphate (Na2HP04) solution as liquid component were prepared. After mixing the powder and liquid constituents, injectable and self-setting calcium phosphate cements (...
متن کاملPreparation of Chitosan Nanoparticles Loaded by Dexamethasone Sodium Phosphate
Biodegradable nanoparticulate carriers, have important potential applications for administration of therapeutic molecules. Chitosan based nanoparticles have attracted a lot of attention upon their biological properties such as biodegradability, biocom-patibility and bioadhesivity. The aim of the present investigation was to describe the synthesis and characterization of novel biodegradabl...
متن کاملPreparation of injectable 3D-formed beta-tricalcium phosphate bead/alginate composite for bone tissue engineering.
A novel, injectable bone tissue engineering material was developed that consisted of beta-tricalcium phosphate (beta-TCP) beads as the solid phase and alginate as the gel phase. To prepare the instantaneously formed composite scaffold, an aqueous calcium chloride solution was dried on the surface of beta-TCP beads and crosslinked with an alginic acid sodium solution, thereby forming stable beta...
