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...
متن کامل‘Solomon’s Bottle’: a Glass Bottle in Tehran and Abbasid Glass Floors in Mesopotamia and the Levant
The article discusses a scarcely known medium of architectural decoration in Abbasid palaces, transparent glass tiles, and reports on the discovery of the largest known assemblage of fragments of such tiles in Tehran, in a bottle of the Glassware and Ceramics Museum of Iran. The first part deals with the visual and material aspects of the use of transparent glass tiles, based on archaeologica...
متن کاملبررسی 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...
Antibacterial effect of morphous (poly-crystalline) and amorphous (glass) nano-bioactive glass 45S5 on Streptococcus mutans
Objective: Bioactive glass 45S5 is a surface reactive glass-ceramic biomaterial, developed in 1969. BAG 45S5 with particle size of 20-60 nm has the ability of bone regeneration, broad spectrum antibacterial effect, repairs and replaces diseased or damaged bone. The aim of this study was to evaluate the antibacterial activity and determine MIC and MBC values of nano-BAG45S5 on Streptococcus mu...
متن کاملLuminescence 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 ...
