Description

Изобретение относитс к области выращивани монокристаллов бифта.тата кали .The invention relates to the field of growing monocrystals of biphite potassium carbonate.
Известен способ выращивани монокристаллов бифталата кали методом осаждени вещества, например, снижением температуры из водного раствора с добавками.There is a known method of growing potassium biphthalate monocrystals by the method of precipitating a substance, for example, by lowering the temperature from an aqueous solution with additives.
Известный способ не позвол ет кристаллизовать бифталат кали из его стехиометрического водного раствора ири температурах ииже 25°С, так как при этих температурах стехиометричеекие составы располагаютс в пределах пол устойчивости соли KzCsH O X Х4С8НбО4Х4Н2О.The known method does not allow the potassium bphthalate to crystallize from its stoichiometric aqueous solution at temperatures below 25 ° C, since at these temperatures the stoichiometric compounds are located within the stability field of the salt KzCsH O X X4C8HbO4X4H2O.
Это обсто тельство снижает выход кристаллов при их выращивании методом снижени температуры.This circumstance reduces the yield of crystals when they are grown by the method of lowering the temperature.
Цель изобретени - расширение температурного диапазона процесса кристаллизации.The purpose of the invention is to expand the temperature range of the crystallization process.
Это достигают тем, что в раствор ввод т в качестве добавки гидроокись кали преимущественно в количестве 1,5-5% от веса растворенного вещества.This is achieved by adding potassium hydroxide as an additive in the amount of 1.5-5% by weight of the solute as an additive.
Разработанный способ позвол ет повысить выход монокристаллов бифталата кали на %.The developed method allows to increase the yield of potassium biphthalate monocrystals by%.
Пример. Готов т раствор бифталата кали в воде, насыщенный при 45°С, с добавкой КОП в количестве 1,5% от веса растворенного вещества. Одпим из известных способов, например, спижением темиературы задают пересыщение раствора, после чего ведут кристаллизацию на затравке. При выращивании кристаллов методом снижени температуры раствор ио мере роста кристалла постепенно охлаждают.Example. Prepare a solution of potassium biphthalate in water, saturated at 45 ° C, with the addition of KOP in the amount of 1.5% by weight of the solute. Odim of the known methods, for example, by lowering the temperature, set the supersaturation of the solution, after which crystallization is carried out on a seed. When crystals are grown by lowering the temperature, the solution gradually cools as the crystal grows.
