Abstract
Изобретение относитс к способам получени особо чистых веществ, в частности сульфида цинка. Сущность способа заключаетс в том, что к раствору соли цинка добавл ют гидроксид натри До полного растворени осадка, затем приливают раствор тиомочевины при посто нном перемешивании смеси. Осаждение ведут в магнитном поле с напр женностью 90-1100 Эрстед и при 60-90°С. Исходные реагенты берут с концентрацией 0,1 М. При этом получают одновременный по грансоставу продукт с размером частиц не более 0,08 мкм, 1 з.п.ф-лы, 1 табл.The invention relates to methods for producing highly pure substances, in particular zinc sulfide. The essence of the method is that sodium hydroxide is added to the zinc salt solution until the precipitate is completely dissolved, then a solution of thiourea is poured with constant stirring of the mixture. The deposition is carried out in a magnetic field with a strength of 90-1100 Oersted and at 60-90 ° C. The starting reagents are taken with a concentration of 0.1 M. In this case, a product with a particle size of not more than 0.08 μm, 1 zpf-l, simultaneous in composition is obtained, 1 table.
Description
Изобретение относитс к способам получени сульфида цинка, используемого в производстве люминофоров, оптоэлектрон- ных приборов и т.д.The invention relates to methods for producing zinc sulfide used in the manufacture of phosphors, optoelectronic devices, etc.
Целью изобретени вл етс повышение дисперсности сульфида цинка.The aim of the invention is to increase the dispersion of zinc sulfide.
П р и м е р. К 50-ти мл 0,1 М раствора сульфата цинка добавили концентрированного раствора гидроксида натри до полного растворени осадка. Затем при посто нном перемешивании приливали постепенно до 100 мл 0,1 М раствора тиомочевины ,температуру смеси поддерживали до 90°С. Во все врем операций сосуд с компонентами находилс в магнитном поле напр женностью 1100 Эрстед.PRI me R. A concentrated sodium hydroxide solution was added to 50 ml of a 0.1 M zinc sulfate solution until the precipitate was completely dissolved. Then, with constant stirring, gradually up to 100 ml of a 0.1 M thiourea solution was added, the temperature of the mixture was kept at 90 ° C. During all operations, the vessel with the components was in a magnetic field with a strength of 1100 Oersted.
Полученный сульфид цинка содержит зерна, не превышающие 0.08 мкм с высокой равномерностью размеров.The resulting zinc sulfide contains grains not exceeding 0.08 μm with high uniformity of sizes.
Результаты опытов представлены в таблице . The results of the experiments are presented in the table.
Как следует из таблицы, осаждение сульфида цинка под воздействием магнитного пол значительно повышает оптическую плотность суспензии, что доказывает увеличение степени дисперсности продукта .As follows from the table, the deposition of zinc sulfide under the influence of a magnetic field significantly increases the optical density of the suspension, which proves the increase in the degree of dispersion of the product.
