Design and Properties of Glass-Ceramics
The regenerator glass-ceramic is produced as a honeycomb product for a turbine engine heat exchanger. It is made from a powdered glass frit, which as a slurry can impregnate paper that is wound as alternately corrugated sheets on a wheel. After firing, a porous ceramic regenerator wheel is produced that allows energy to be transferred from hot exhaust gases to the cold intake air in the turbine...
متن کاملInvestigation of crystallization and sinterability properties of BaO-Al2O3-SiO2 glass-ceramics containing K2O and B2O3
BaO -SiO2-Al2O3 glass ceramics containing K2O and B2O3 were prepared using conventional melting of powered batches, quenching in water and crystallization of sintered glass. XRD patterns introducehexacelsian and celsian as two major crystallized phases in sintered glass-ceramics. Presence of K2O enhances crystallization of hexacelsianin comparison withB2O3.Observations showed sintering temperat...
متن کاملElastic Properties of substituted 45S5 Bioactive Glasses and Glass - Ceramics
CuO, Fe2O3, MnO2 and ZnO substituted 45S5 bioactive glasses were prepared. Glass derived Bioactive Glass ceramics were obtained through controlled crystallization of bioactive glasses. The formed crystalline phases in bioactive glass ceramics were identified using X ray diffraction (XRD) analysis. Density and ultrasonic wave velocities of bioactive glasses and glass ceramics were measured and u...
متن کاملSintering Behavior and Properties of Iron-Rich Glass-Ceramics
Iron-rich glass-ceramics were obtained by the sintering of two glass powders, labeled G1 and G2, at heating rates of 5° and 20°C/min followed by an isothermal step in the 850°–1050°C temperature interval. The sintering process was evaluated by the linear shrinkage; the closed porosity was estimated by density measurements; the structure and the morphology of the glass ceramics were observed by ...
متن کاملBiocompatibility and Physical Properties of Doped Bioactive Glass Ceramics
Biocompatibility of a new bioactive glass composition for medical applications was evaluated with the addition of fluorides, such as CaF2 and MgF2, for the substitution of Na2O in the conventional bioactive glass composition (SiO2-CaO-Na2O-P2O5). Also, the physical properties of these glass ceramics were investigated. When B2O3 was added as a Na2O substitution, the thermal expansion coefficient...
