Description
Известен способ выращивани монокристаллов йодноватокислого кали из чистых водных растворов при условии температурного перепада и свободной конвекции раствора.There is a known method of growing potassium iodate monocrystals from pure aqueous solutions under the condition of temperature difference and free convection of the solution.
Однако выращивание монокристаллов по известному способу требует больших объемов, технически сложно, а дл получени крупных кристаллов практически непригодно вследствие легкости образовани паразитических кристаллов.However, growing single crystals by a known method requires large volumes, is technically difficult, and is practically unsuitable for obtaining large crystals due to the ease of formation of parasitic crystals.
Предлагаетс способ выращивани монокристаллов йодноватокислого кали , позвол ющий получать крупные кристаллы хорошего качества , пригодные дл практических и исследовательских целей- Это достигаетс тем, что к раствору добавл ют свободную йодноватую кислоту (НЮз).A method is proposed for growing monocrystals of potassium iodate, which makes it possible to obtain large crystals of good quality suitable for practical and research purposes. This is achieved by adding free iodic acid (HBH) to the solution.
Способ может быть осуществлен следующим образом. Трубку (диаметром 30-50 мм и длиной 300-500 жж) заполн ют раствором йодноватокислого кали (КЮз), содержащим 10-13% (весовых) йодноватой кислоты (НЮз) от количества йодноватокислого кали . На поверхность раствора наливают нейтральное масло дл предотвращени испарени В нижней части трубки находитс кристаллическое вещество (КЮз). Трубку помещают в термостат так, чтобы поверхность твердого вещества находилась «иже примерно на 10 мм уровн теплоносител в термостате . Температуру верхней части трубки поддерживают около 25°. По истечении времени (от 1 до 3 час.), необходимого дл установлени режима конвекции и равномерной концентрации раствора в трубке, в верхнюю ее часть помещают кристаллоносец с затравкой и привод т его в движение (лучше в возвратно-поступательное)- Процесс выращивани монокристаллов протекает со скорост ми от долей миллиметра до 5-7 .«ж в сутки по ребру. В результате получают крупные сростки из восьми оптически однородных (прозрачных) монокристальных блоков (5X5X5 мм), которые используютс после распиловки№ 148016-2Предмет изобретени The method can be carried out as follows. The tube (30–50 mm in diameter and 300–500 mm long) is filled with a solution of potassium iodate (CUz) containing 10–13% (by weight) iodic acid (HBH) of the amount of potassium iodate. A neutral oil is poured onto the surface of the solution to prevent evaporation. A crystalline substance (CUS) is located at the bottom of the tube. The tube is placed in a thermostat so that the surface of the solid is “approximately the 10 mm level of the heat transfer medium in the thermostat. The temperature of the upper part of the tube is maintained at about 25 °. After the time (from 1 to 3 hours) required to establish the mode of convection and the uniform concentration of the solution in the tube, the crystal bearer with seed is placed in its upper part and set in motion (better in reciprocating) - The process of growing single crystals proceeds with speeds from fractions of a millimeter to 5-7. “Well per day along the edge. As a result, large intergrowths of eight optically homogeneous (transparent) single-crystal blocks (5X5X5 mm) are obtained, which are used after sawing No. 148016-2.
