INCREASING ACCURACY OF DETERMINING QUANTITATIVE COMPOSITION OF TERNARY VITREOUS CHALCOGENIDES OF GLASS AND FILMS OF VARIABLE COMPOSITION A(BC) Russian patent published in 2013 - IPC G01N23/223

Abstract RU 2489707 C1

FIELD: chemistry.

SUBSTANCE: to increase accuracy of determining quantitative composition to ±0.0002 (on x and y) of ternary vitreous glass and films of a variable composition A_x(B_yC_1-y)_1-x (where A=As, Sb, Bi; B=Se, Te; C=Ge), used in phase memory devices (optical discs of various formats and non-volatile random-access memory devices), areas under characteristic lines of atoms A, B and C and X-ray fluorescence spectra of glass and films of a known composition (standards) and vitreous films of a variable composition are juxtaposed.

EFFECT: high accuracy of determining quantitative composition of ternary vitreous chalcogenides of glass and films of variable composition.
