PROCESS OF PREPARATION OF SAMPLES MATERIALS FOR ANALYSIS

摘要

FIELD: analytical chemistry. SUBSTANCE: invention relates to high-temperature superconducting materials. For destruction of structure of high-temperature superconducting material and homogenization of composition sample is treated with solution of hydrogen peroxide with proportion: high-temperature superconducting material: HO= 1.0: (0.2-0.3). Produced powder is pressed into tablets and quantitative X-ray-fluorescent analysis of key element with the use of standard samples for comparison of mixtures on the basis of oxides and carbonates of analyzed elements is conducted. EFFECT: simplified process of analysis.
