Density of the systems (NaF/AlF3)—AlPO4 and (NaF/AlF3)—NaVO3

Chemical Papers, 2011
AbstractThe densities of two systems of molten mixtures (NaF/AlF3)—NaVO3 and (NaF/AlF3)—AlPO4 were measured using an Archimedean method. Each molten mixture contained varying amounts of “impurity” constituents. The measurements were performed at various NaF/AlF3 mole ratios (CR, cryolite ratio), equal to 3, 2.5, 2, and 1.5.

Microstructures of Alkali Halide Eutectics LiF‐NaF and NaF‐NaCl

Journal of the American Ceramic Society, 1965
The microstructures of the directionally frozen eutectics are described and it is shown that the interphase separations vary in a manner similar to metallic eutectics. Addition of impurity to the binary mixtures produces cellular growth and the reactions of the lamellar LiF‐NaF and ribbonlike NaF‐NaCl to these freezing conditions are described.

The relation between aging, aortic NaF avidity and coronary artery NaF avidity: A NaF PET CT study

The Journal of Nuclear Medicine, 2013
Objectives: Vascular calcification is a strong independent predictor of cardiovascular events and all-cause mortality. This study investigated the correlation between aortic and coronary artery calcification metabolism in relation to age in a cohort of healthy controls.

Experimental results on the viscosity, electrical conductivity, and thermoelectric power of ionic liquid mixtures formed after the melting of the NaF???LiF???LaF??? and NaF???LiF???NdF??? eutectics in the temperature range (580???1000) ??C are presented. It is found that the temperature coefficient of thermoelectric power of both ionic mixtures changes

Sodium Fluoride (NaF)

1997
Publisher Summary This chapter presents the room-temperature values of the refractive index n and the extinction coefficient k for sodium fluoride (NaF). The chapter discusses the data available in the literature regarding the optical properties of this material and reviews the values of n and k obtained by interpreting spectral dependences of the ...
