Earth Metals Contained in Samarskite

Preparation of rare earth metals

The production of over 400 grams of pure gadolinium metal by reduction of the anhydrous chloride by calcium in tantalum vessels is described; yields were over 97%. The use of the same techniques in an attempt to prepare yttrium metal were partially successful.

Spin Dependent Transport and Magnetic Ordering in Rare Earth Metals

Electron-phonon coupling in the rare-earth metals.

Metals contained and leached from rubber granulates used in synthetic turf areas.

The aim of this study was to quantify metals contained in and leached from different types of rubber granulates used in synthetic turf areas. To investigate the total content of metals, ca 0.5 g of material was added with HNO(3), HF and HClO(4) and microwave digested with power increasing from 250 W to 600 W. Leachates were prepared by extraction of about 5.0 g of material at room temperature f...

The RARe eARTh MeTAlS And TheiR CoMpoundS Thermal Analysis of Rare earth nitrate Mixtures

26 Einstein J. Biol. Med. (2008) 24:26-31. A method of analysis is proposed which utilizes the characteristic melting points of the hydrated salts and the liquidus curves of the binary salt mixtures for the estimation of the composition of rare earth mixtures. Several binary salt systems were investigated, employing very pure simple and double rare earth nitrates to provide basic information co...
