На первом этапе с использованием метода фундаментальных параметров (МФП) проводили экспрессный полуколичественный анализ образцов керамики и промежуточных продуктов синтеза с установлением их предварительного состава. На втором этапе по построенным градуировочным зависимостям определяли количественный состав проб. Для построения градуировочных зависимостей аналогичным получению исследуемых керамических образцов способом синтезировали серию образцов сравнения, содержащих 3,16 – 56,55 % Y, 8,78 – 71,0 % Yb и 12,83 – 19,70 % Nb. Выбраны аналитические линии элементов, свободные от спектральных наложений, и условия проведения РФА (ток и напряжение рентгеновской трубки, время экспозиции, способ учета фона вблизи аналитических линий). Относительное стандартное отклонение результатов определения Y, Yb и Nb в образцах керамики не превышало 0,66 %, относительная погрешность составляла не более 1,63 %. Полученные результаты сравнивали с расчетными содержаниями аналитов в пробах стехиометрического состава и с результатами анализа реальных образцов керамики методом ИСП-АЭС. Разработанная методика позволяет определять основные компоненты в образцах керамики и может быть использована в целях аналитического контроля процесса синтеза параниобатов РЗЭ.</p></abstract><trans-abstract xml:lang="en"><p>A two-stage technique for X-ray fluorescence analysis of ceramic samples of composition Y3–xYbxNbO7 (where x = 0 – 3) has been developed. At the first stage, using the method of fundamental parameters (FPM), a rapid semi-quantitative analysis of ceramic samples and products of intermediate synthesis was carried out to determine their preliminary composition. At the second stage, the quantitative composition of the samples was determined using the constructed calibration dependencies. To construct calibration dependencies a series of reference samples containing 3.16 – 56.55% Y, 8.78 – 71.0% Yb, and 12.83 – 19.70% Nb was synthesized using a method similar to that used for preparation of the ceramic samples under study. Analytical lines of elements free from spectral overlaps and XRF conditions (current and voltage of an X-ray tube, exposure time, method of taking into account the background near the analytical line) were selected. The relative standard deviation of the results of Y, Yb, and Nb determination in ceramic samples did not exceed 0.66%, the relative error was no more than 1.63%. The results obtained were compared with the calculated content of analytes in the samples of stoichiometric composition and with the results of ICP-AES analysis of real ceramic samples. The developed technique provides determination of the main components of ceramic samples and can be used for analytical control of synthesis of rare earth paraniobates.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>керамические материалы</kwd><kwd>рентгенофлуоресцентный анализ</kwd><kwd>параниобаты редкоземельных элементов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ceramic materials</kwd><kwd>X-ray fluorescence analysis</kwd><kwd>paraniobates of rare earth elements</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены за счет гранта Российского научного фонда (проект № 20-13-00180-П) с использованием оборудования ЦКП ФМИ ИОНХ РАН</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Oses C., Toher C., Curtarolo S.
