METHOD OF LUMINESCENT DETERMINATION OF THE CONTENT OF SAMARIUM AND NEODYMIUM OXIDES IN EUROPIUM THE CONTENT OF SAMARIUM AND NEODYMIUM OXIDES IN EUROPIUM OXIDE

摘要

In the method of determining the content of the luminescent samarium and neodymium oxides europium oxide as a solid boric acid reagent is used. Calcining the mixture is carried out in a stream of dry hydrogen for 40-50 minutes at 800- 900 & amp; deg; C. Measurement of luminescence is recommended carried out at a wavelength of 650-900 nm radiation samarium and neodymium 1000-1200 nm. 1 ZP f-ly. Table 2.
