This research has produced foamed glass-ceramics from coal fired power station furnace bottom ash (FBA) and soda-lime-silica glass. The as-received FBA was wet milled with different additions of resultant slurry dried formed into a powder. powder pressed sintered at range temperatures fluxing agent (sodium tetraborate decahydrate), bubble stabilising additive (tri-sodium phosphate) bloating (ca...

Nanoporous glass-ceramics were prepared with composition 45CaO-25TiO2-35P2O5 (mol%). Two molar percent of Na2O was added as a flux to the composition. With the aforementioned composition, glass melted and crystallized into glass-ceramics containing β-Ca3(PO4)2 and CaTi4(PO4)6 as the main phases. The differential thermal analysis (DTA) was conducted to determine the suitable temperatures f...

In order to improve the chemical stability and modify the biodegradability of bio-glass ceramics materials for certain applications, a correlation between structural and biological properties of bio-glass ceramics is very essential and these properties are found to be greatly dependent on the composition and synthetic parameters of the material. In the present work, an attempt has been made to ...

Abstract — Fe2O3 substituted 45S5 bioactive glasses were prepared. Glass derived Bioactive Glass ceramics were obtained through controlled crystallization of bioactive glasses. Nucleation and crystallization regimes were determined by the parameters obtained from differential thermal analysis (DTA) of bioactive glasses. The formed crystalline phases in bioactive glass ceramics were identified u...

Ceramics and glass ceramics based on industrial waste have been widely recognized as competitive products for building applications; however, there is a great potential for such materials with novel functionalities. In this paper, we discuss the development of magnetic sintered glass ceramics based on two iron-rich slags, coming from non-ferrous metallurgy and recycled borosilicate glass. The s...

BACKGROUND Bioactive glass-ceramics have the ability to directly bind to bones and have been widely used as bone graft substitutes due to their high osteoconductivity and biocompatibility. CaO-SiO2-P2O5-B2O3 glass-ceramics are known to have good osteoconductivity and are used as bone graft extenders. METHODS This study aimed to evaluate the effects of the resorbing properties of glass-ceramic...
