Abstract
СПОСОБ ПОЛУЧЕНИЯ ФТОРОТАНТАЛАТОВ ЩЕЛОЧНЫХ МЕТАЛЛОВ термообработкой шихты, состо щей из фторида щелочного металла и соединени тантала , отличающийс тем, что, с целью упрощени аппаратурного оформлени , используют шихту, состо щую из оксида тантала (V), бифторида аммони и фторида щелочного металла , и процесс ведут при температуре 400-800 С до прекращени ввделени паров фторида аммони . (ЛA method for producing alkali metal fluoride tantalates by heat treating a charge consisting of alkali metal fluoride and a tantalum compound, characterized in that, in order to simplify the instrumentation, a mixture consisting of tantalum oxide, V, ammonium bifluoride, and a mixture of a mixture and a mixture of a mixture and a mixture and an ingredient and a mixture of a mixture and a mixture of tantalum and a mixture of tantalum, and ammonium fluoride are used. is carried out at a temperature of 400-800 ° C until the intake of ammonium fluoride vapor is terminated.

Изобретение относитс к способам получени комплексных фторидов тантала и щелочных метаплов, которые примен ютс в научных исследовани х. Гептафторотанталат кали также примен етс дл получени металлического тантала электролизом солевых расплавов и пирометаллургическим способом.The invention relates to methods for producing complex tantalum fluorides and alkaline metaplates that are used in scientific research. Potassium heptafluorotantalate is also used to produce metallic tantalum by electrolysis of salt melts and the pyrometallurgical method.
Целью изобретени вл етс упрощение аппаратурного оформлени способа.The aim of the invention is to simplify the instrumentation of the method.
р и м е р 1. 100 г сме .П шивают с 129 г и 26,3 г KF (мольное отношение 1:10:2). Приготовленную шихту прокаливают при 400 С до прекращени выделени паров ЫН4Р. Полученла в количестве 151 г соль идентифицирована как KTaFg,EXAMPLE 1 100 g of mixed sew with 129 g and 26.3 g of KF (molar ratio 1: 10: 2). The prepared mixture is calcined at 400 ° C until the evolution of the NH4P vapor stops. Received in the amount of 151 g salt identified as KTaFg,
Пример 2. 100 г смешивают с 129 г и 52,5 г KF (мольное отношение 1:10:4). Приготовленную шихту прокаливают приExample 2. 100 g are mixed with 129 g and 52.5 g of KF (molar ratio 1: 10: 4). The prepared mixture is calcined at
750 С до прекращени вьщелени паров . Полученна в количестве 177 г соль идентифицирована как .750 ° C until vaporization is stopped. The resulting 177 g of salt is identified as.
Пример 3. 100 г смешивают с 129 г NHjjHF и 78,7 г KFExample 3. 100 g are mixed with 129 g NHjjHF and 78.7 g KF
(мольное отношение 1:10:6). Приготовленную шихту прокаливают при 800°С до прекращени выделени паров . Полученна в количестве 203 г соль идентифицирована как .(molar ratio 1: 10: 6). The prepared mixture is calcined at 800 ° C until the evaporating emission ceases. The salt obtained in an amount of 203 g is identified as.
Таким образом, предлагаемьй способ позволит проводить процесс термической обработки на воздухе в одну стадию, что существенно упростит его аппаратурное оформление.Thus, the proposed method will allow the process of heat treatment in air in one stage, which will significantly simplify its instrumentation.
