Изобретение относитс к области контрол материалов, нримен емых в электронной технике .The invention relates to the field of control of materials used in electronic equipment.
По сун.1.ествуюш,им способам спектральное определение примесей в платине и различных сплавах на ее основе провод т корольковым или глобульным методами, которые предусматривают р д дополнительных операций, предшествующих анализу: сплавление эталонов и проб с электролитическим серебром в графитовых тигл х, обжатие корольков на прессе или проковку их на наковальне; процесс сжигани эталонов и проб требует об зательного использовани водоохлаждаемых электродов с серебр ными наконечниками. According to Sun. 1stW, they are subjected to spectral determination of impurities in platinum and various alloys on the basis of which they are carried out using king or globular methods, which involve a number of additional operations preceding the analysis: fusion of standards and samples with electrolytic silver in graphite crucibles, reduction korolkov on the press or forging them on the anvil; The process of burning standards and samples requires the obligatory use of water-cooled electrodes with silver tips.
Предлагаемый способ отличаетс от известного тем, что, с целью сокращени расхода платипы и упрощени методики анализа, анализируемый снлав перевод т в металлическую губку путем восстановлени хлороплатината аммони ; губку тщателыю растирают в ступке из оргстекла в присутствии этилового спирта .The proposed method differs from the known one in that, in order to reduce the consumption of platyps and simplify the analysis procedure, the analyzed synthesis is converted into a metal sponge by reducing ammonium chloroplatinate; A sponge is pounded in a plexiglas mortar in the presence of ethyl alcohol.
Целесообразно использовать дл приготовлени синтетических эталонов в качестве основы непосредственно анализируемый материал , прнмесп в котором определ ют по методу добавок.It is advisable to use directly analyzed material for the preparation of synthetic standards as a basis, which is determined according to the additive method.
От поступивщей на анализ пробы отбирают по две навески весом 70 мг кажда , перевод т пх в платиновую губку, смешивают с графитовым пopoшкo oco6oi i очистки в отпошении 1 : 4 и сжигают в дуге посто нного тока при 15а и времени экспозиции 50 сек.A sample of 70 mg each weighing each is taken from the incoming sample for analysis, transferred into a platinum sponge, mixed with a graphite powder oco6oi i cleaning at 1: 4 and burned in a DC arc at 15a and an exposure time of 50 s.
Спектры фотографируют кварцевым спектрографом ИСП-30 через трехступенчатый ослабитель , система освещени щели трехлинзова , ширина щели 0,012 мм; промежуточна диафрагма 5 мм, фотопластинки УФШ и ЭС чувствительностью 2,8 ед.The spectra are photographed with an ISP-30 quartz spectrograph through a three-stage attenuator, a three-lens slit illumination system, a slit width of 0.012 mm; intermediate aperture 5 mm; photographic plates UFS and ES with sensitivity 2.8 units.
Предмет изобретени Subject invention
Снособ колнчественного спектрального определени примесей в сплаве платина-барий нутем сж)ганп в дуге эталонов и образцов, отличающийс тем, что, с целью сокращени расхода платины и уирощеии методики анализа , анализируемый сплав перевод т в металлическую губку и добавл ют примеси в виде окислов металлов, причем полученные так)1м образом эталоны и образцы анализируют известным путем.A method for the qualitative spectral determination of impurities in a platinum-barium alloy by chitol ghnp in an arc of standards and samples, characterized in that, in order to reduce platinum consumption and improve the analytical method, the alloy being analyzed is transferred into a metal sponge and impurities in the form of metal oxides are added , and so obtained) in the first way standards and samples are analyzed in a known way.
