EFFECTS OFVARIOUS NUCLEATION AGENTS ON CRYSTALLIZATION KINETIC OFLAS GLASS CERAMIC
The effect of Y2O3, CeO2, P2O5, ZrO2 and TiO2 in single, double and triple form on crystallization mechanism of Li2OAl2O3- SiO2(LAS) glass-ceramic system was investigated .The nucleation and crystallization peak temperatures of optimized samples in each group were determined by Ray & Day method .The crystalline phase was determined by the X-ray diffractometery .The micro-structure of the sample...
متن کاملGlass and Glass-Ceramic Scaffolds: Manufacturing Methods and the Impact of Crystallization on In-Vitro Dissolution
Synthetic biomaterials mimicking bone morphology have expanded at a tremendous rate. Among all, one stands out: bioactive glass. Bioactive glasses opened the door to a new genre of research into materials able to promote the regeneration of functioning bone tissue. However, despite their ability to promote cell attachment, proliferation and differentiation, these materials are mainly used as gr...
متن کاملPorous apatite-wollastonite glass-ceramic as an intramedullary plug.
We evaluated the efficacy and biocompatibility of porous apatite-wollastonite glass ceramic (AW-GC) as an intramedullary plug in total hip replacement (THR) for up to two years in 22 adult beagle dogs. Cylindrical porous AW-GC rods (70% porosity, mean pore size 200 microm) were prepared. Four dogs were killed at 1, 3, 6 and 12 months each and six at 24 months after implantation. Radiological ev...
متن کاملIn vitro evaluation of apatite/wollastonite glass–ceramic nano biocoatings on 316 alloys by plasma-sprayed
Among bioactive ceramics, the apatite/wollastonite (A/W) glass ceramic, containing apatite and wollastonite crystals in the glassy matrix, has been largely studied because of good bioactivity and used in some fields of medicine, especially in orthopedics and dentistry. However, medical applications of bioceramic are limited to non-load bearing applications because of their poor mechanical prope...
متن کاملEnhancing the bioactivity of a calcium phosphate glass-ceramic with controlled heat treatment
In this paper synthesis and characterization of a bioactive calcium phosphate glass-ceramic is presented, synthesized using a facile method. The glass-ceramic samples are synthesized with heat treating the parent glass at appropriate temperatures, where different calcium phosphate crystalline phases are grown in the parent glass samples during the heat treatment. The amounts of elements a...
