Davron Rakhmonovich Djuraev , Doctor Of Physical And Mathematical Sciences, Professor Of Bukhara State University, Uzbekistan Mokhigul Madiyorovna Jamilova , Master’s Student Of Bukhara State University, UzbekistanAbstract
The article studies the physical properties of rare earth metals, pays special attention to their unique properties, studies the main aspects of the application of rare earth metals in industry.
Also, the structure and stability of various forms of sesquioxides of rare earth elements, in particular, europium, as well as the effect of the method of oxide preparation on its structure and properties are considered. The analysis of the ongoing phase transformations of rare earth metals is made. The article emphasizes the use of correct choices to achieve a large technical and economic effect when using rare earth metals in industry.
The article is intended for teachers working in the field of physics and chemistry, as well as for students of the specialty "physics and chemistry".
Keywords
