Iron Phosphate Glass-ceramics
The crystallization of 40Fe2O3-60P2O5, 10ZnO-30Fe2O3-60P2O5 and (43.3−x)PbO–(13.7+x)Fe2O3–43P2O5, (0 < x < 30), glasses and glassceramic have been investigated. The structural evolution of glasses during heat treatment at various temperatures and the tendency for crystallization for series of glasses with modified composition are characterized by a dendrite-like phase separation in the early st...
متن کاملAddition of Alumina to Nanoporous Calcium Titanium Phosphate Glass-Ceramics and its Effects on Crystallization Behavior
Microporous Calcium Titanium Phosphate glass-ceramics have many uses in high-tech industries. For example, they have applications in catalysts industry. In this study, different molar percentages of alumina were added to a glass with P2O5 30, CaO 45, TiO2 25 (mol%) composition. The samples were melted at 1350°C and crystallization heat treatment was performed on...
متن کاملUltrasonic characterisation of calcium phosphate glasses and glass-ceramics with addition of TiO2
Calcium phosphate based glasses with different concentrations of TiO2 (0 to 2.5 mol%) were prepared and their corresponding glass-ceramics were obtained by controlled heat treatments. The amorphous nature of glasses and the presence of crystalline phases in glass-ceramics were studied through XRD studies. Density, molar volume, ultrasonic velocities, attenuation, elastic constants and microhard...
متن کاملProduction of porous Calcium Phosphate (CaP) ceramics with aligned pores using ceramic/camphene-based co-extrusion
BACKGROUND Calcium phosphate (CaP) ceramics are one of the most valuable biomaterials for uses as the bone scaffold owing to their outstanding biocompatability, bioactivity, and biodegradation nature. In particular, these materials with an open porous structure can stimulate bone ingrowth into their 3-dimensionally interconnected pores. However, the creation of pores in bulk materials would ine...
متن کاملPorous hydroxyapatite and biphasic calcium phosphate ceramics promote ectopic osteoblast differentiation from mesenchymal stem cells.
Because calcium phosphate (Ca-P) ceramics have been used as bone substitutes, it is necessary to investigate what effects the ceramics have on osteoblast maturation. We prepared three types of Ca-P ceramics with different Ca-P ratios, i.e. hydroxyapatite (HA), beta-tricalcium phosphate (β-TCP), and biphasic calcium phosphate (BCP) ceramics with dense-smooth and porous structures. Comprehensive ...
