Determination of Al in Rare Earth Fluoride by ICP-AES

In this paper, the study has been made on determining Cl - content in rare earth fluoride The method can determine 0 005% Cl -,its RSD ( relative standard deviation )is 9 30% The method is quick and accurate The method has been applied to the determination of Cl - in rare earth fluoride with satisfactory result

The economical and stable method of determination has been set up by orthogonal design method,and the determination of Cl - in rare earth fluoride have been explored theoretially.

Principles of reactions in the synthesis of rare earth fluorides in RE_2O_3-NH_4HF_2 systems;

Rare earth fluorides are very important matrix for luminescence and one of the important studied materials in the solid-electrolyte field as well.

The results show that the nature of fluoride source plays important roles in controlling the size and morphology of the resulting rare earth fluorides.

This paper designs and homemakes xeransis fluorination furnace,studies the technical processes of preparing rare earth fluoride.

The orthogonal design method is used for preparation of rare earth fluoride by rare earth oxide(Gd_2O_3) fluorination with NH_4HF_2 in this paper.

Synthesis and application of nanorare-earth fluoride lubricating oil additives;

The light rare earth fluorides, rare earth oxyfluorides, and the complex of rare earth fluoride with NH 4F were rapidly synthesized in a microwave radiation field by NH 4F reacted with rare earth oxides.
