Luminescence Properties of Oxyfluoride Glass and Glass Ceramic Doped with Y3 + Ions

 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 ...

بررسی فرمولاسیون الیاف e-glass و ecr-glass جهت استفاده در لوله های فاضلاب

الیاف شیشه، الیاف ظریف خمش پذیری از خانواده شیشه با اجزاء اصلی sio2-al2o3-cao-mgo و ناخالصی های قلیایی، اکسید های معدنی tio2,fe2o3 و افزودنی b2o3 و فلئور می باشد و در حالت مذاب بصورت رشته های نخی شکل، رشته رشته می شود.الیاف شیشه به دو گروه اصلی پشم شیشه و الیاف پیوسته تقسیم بندی می شود و الیاف شیشه نیز بر حسب شرایط مصرف به چندین نوع e-glass , a-glass, c-glass , r-glass , s-glass , ecr-glas...

PREPARATION OF Fe/GLASS COMPOSITE BY REDUCTION OF Na2O– Fe2O3–B2O3–SiO2–ZnO GLASS AND GLASS CERAMICS

In the present study, the feasibility of α-Fe ferromagnetic phase formation in glass and glass-ceramic by reduction in hydrogen atmosphere have been investigated. The glass with the composition of 35Na 2 O–24Fe2O3–20B 2O3 – 20SiO 2 –1ZnO (mol %) was melted and quenched by using a twin roller technique. As quenched glass flakes were heat treated in the range of 400-675 °C for 1-2 h in h...

Implicit learning in dynamic decision making: A glass-box approach

Although simulations can be useful tools to train dynamic decision making (DDM) skills, studies show that mere practice with simulated environments leads to limited improvements in performance. Simulated environments often show little or no transparency about the underlying structure. Making information about the system and the consequences of decisions available to users has been found to enha...
