Description
Изобретение относитс к способу получептш монокристаллов тугоплавких веществ, в особенности фтор-слюды, которые могут быть использованы в качестве диэлектриков.This invention relates to a process for the preparation of single crystals of refractory substances, especially fluorine-mica, which can be used as dielectrics.
Известен способ получени монокристаллов тугоплавких вепдеств, например кристаллов АЬОз, из раствора в расплаве, заключаюпдийс в том, что исходную шихту смешивают с растворителем, иаиример фтористым свинцом .A known method for producing single crystals of refractory minerals, for example, AO3 crystals, from a solution in the melt, concludes that the initial mixture is mixed with a solvent, and the hydrogen chloride is used in lead fluoride.
Дл повышени качества конечного продукта и упрощени процесса предлагаетс в качестве растворител использовать смесь обезвоженных фторидов элементов I н II групп периодической системы элементов, а в качестве растворимого - поликристаллпческий конечный продукт или смесь компонентов, образуюп их его в процессе реакции. При этом растворитель ввод т в количестве от 3 до 80% (преимущественно 20-60%).To improve the quality of the final product and simplify the process, it is proposed to use as a solvent a mixture of dehydrated fluorides of elements I and II groups of the periodic system of elements, and as a soluble polycrystalline final product or a mixture of components forming it during the reaction. In this case, the solvent is introduced in an amount of from 3 to 80% (preferably 20-60%).
Пример. Химически чистые SiF, Вар2 смешивают со скрапом слюды KMgsLAlSisOiojFg фракции 0,5-1 мм в соотношении SiF 30%, BaFa 37%, слюда 33%, брикетируют и загружают в тигель из малоуглеродистой стали. После этого его вакуумируют и заполн ют аргоном. Внутреннюю поверхность тигл предварительно очищают от ржавчины н дл удалени механических нримесей и жира промывают легколетучей жидкостью .Example. Chemically pure SiF, Var2 is mixed with mica scrap KMgsLAlSisOiojFg fractions 0.5-1 mm in a ratio of SiF 30%, BaFa 37%, 33% mica, briquetted and loaded into a mild steel crucible. After that, it is evacuated and filled with argon. The inner surface of the crucible is pre-cleaned of rust and n to remove mechanical impurities, and the fat is washed with a volatile liquid.
Тигель помещают в молибденовую печь сопротивлени с водородной защнтной средой. Печь разогревают до 1150°С, выдерживают в течение 5 час, а затем температуру со скоростью 1 град/час до температуры 800°С. Затем тигель пзвлекают, слиток разбивают и извлекают кристаллы слюды.The crucible is placed in a molybdenum resistance furnace with a hydrogen protective medium. The furnace is heated to 1150 ° C, maintained for 5 hours, and then the temperature at a rate of 1 deg / hour to a temperature of 800 ° C. Then the crucible is recovered, the ingot is broken and the mica crystals are removed.
