Design and Properties of Glass-Ceramics

چکیده
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 engine. The very low thermal expansion [�5 X 1O-7;oc (0--1000°C)], and high thermal stability (> 1200°C) are important in this application.

Oxyfluoride glass ceramics containing CaF2nano-crystals doped with Y3+ ions were prepared by one-step crystallization of SiO2- Al2O3- CaO- CaF2 glasses at different temperatures. X- ray diffraction (XRD) results have revealed that CaF2 was the only precipitated crystalline phase in glass ceramic samples. According to the XRD results, a glass ceramic was selected as the best sample in order to ...
متن کاملCrystallization Kinetics and Characterization of Nanostructure Mica Glass-Ceramics with Optical Transparency
Transparent glasses in a system of Li2O-MgO-SiO2-Al2O3-Fchemical constituents were prepared by melt quenching method. In the fabrication of nanocrystal glass-ceramics, controlled nucleation and subsequent crystal growth were necessary to avoid loss of transparency. It was therefore important to understand thermal properties and crystallization kinetic...
