Description
Изобретение относитс к области Получени пидратов метаниобатов щелочноземельных металлов , которые могут быть применены дл изготовлени радиокерам ики и монокристаллов .This invention relates to the production of alkaline earth metal methaniobate pidrates, which can be used for the manufacture of radioac ters and single crystals.
Известен опособ получени указанных соеди1нений взаимодействием растворов гидроокиси щелочноземельного металла и метаниобата кали в 1 н. растворе КОН, в котором длительность и сложность процесса, обусловлены его многостадир ность:ю.A known method for obtaining these compounds is the interaction of alkaline earth metal hydroxide and potassium methaniobate solutions in 1N. KOH solution, in which the duration and complexity of the process, are due to its multistage: s.
По предлагаемому способу в качестве исходных компонентов используют фторииобат кали и штрат а1.елочноземельного металла, и процесс ведут в среде аммиака при значеНИ1И рП 8,5-9,0, что упрощает процесс.According to the proposed method, potassium fluoriobate and a contraction of a 1. metal and metal are used as starting components, and the process is carried out in an ammonia environment with a value of 8.5-9.0 pp, which simplifies the process.
Пример. В раствор аммиака с ,5 параллельно npin непрерывном перемещивании вливают раствор фторниобата кали иExample. A solution of potassium fluoro-niobate and
нитрат бари . В процессе осаждени поддерживают рП смеси 8,75. Выпавший осадок ВаЫЬ20б-хН20 отмывают от ионов F и К+ и просущивают при 100° С. barium nitrate. During the precipitation process, an RP of a mixture of 8.75 is maintained. The precipitate of BAB20b-xH20 is washed off from F and K + ions and dried at 100 ° C.
