A NEW GENERATION OF OXYNITRIDE GLASSES CONTAINING FLUORINE
Oxynitride glasses are found as grain boundary phases in silicon nitride ceramics. They are effectively alumino-silicate glasses in which nitrogen substitutes for oxygen in the glass network, and this causes increases in glass transition and softening temperatures, viscosities (by two to three orders of magnitude), elastic moduli and microhardness. Calcium silicate-based glasses containing fluo...
متن کاملبررسی غلظت فلوئور در منابع آب شرب خراسان جنوبی (سال 87-1386)
Background and Aim: There are some traces of fluorine in people's diet and drinking water is its most important means of absorption. The standard 1053 of Iran Standard Institute and Industrial Research recommends the amount of fluorine in water between 0.6 and 1.7 mg/L, depending on temperature. This study was done to determine the amount of fluorine in drinking-water sources of the South Kho...
متن کاملThermodynamic Properties and Phase Equilibria for Liquid Fluorine Using GMA Equation of State
Thermophysical properties of fluorine are interesting because of its applications in different areas of technologyand industry. The computations of thermodynamic properties were performed with the GMA equation of stateunder critical conditions. The present work reports calculations of density, volumetric, and thermodynamicproperties of liquid fluorine on extended ranges of pressure and temperat...
متن کاملAb initio calculations to model anomalous fluorine behavior.
Implanted fluorine is observed to behave unusually in silicon, manifesting apparent uphill diffusion and reducing diffusion and enhancing activation of boron. In order to investigate fluorine behavior, we calculate the energy of fluorine defect structures in the framework of density functional theory. In addition to identifying the ground-state configuration and diffusion migration barrier of a...
متن کاملFluorine content of teas consumed in New Zealand.
Before the rationing of tea was introduced, New Zealand had the third largest annual consumption of tea in the world, namely 8.2 Ib./person. Subsequently, the ration of 2 oz./wcek with extra concessions to people working in factories and offices provided an annual consumption of 6-5 lb./person. Most foods are found to be poor sources of fluorine, even when grown in fluorinerich soils, supposedl...
متن کاملThe Effect of thickness parameter and Fluorine Dopant on Photocatalytic performance of TiO2 thin films
In this study, Pure and doped titania sols with Fluorine (F/Ti:0.06) dopant, were prepared by sol-gel method and Ammonium Fluoride(NH4F) as the precursor. They were deposited on glass substrates (soda lime) in a certain(optimum) nanometric thickness by the dip coating method. Coated samples were dried and calcined under the specific rate. Phase composition and optical properties of coatings wer...
