Description
Известны способы очистки закиси никел , получаемой пз гидрата закиси. Однако гидрат закиси никел , получаемый обычно путем обменной реакции или электролитическим методом и идущий на приготовление закиси никел , требует очень длительной промывки, часто с применением вакуум-насоса.Known methods of purification of nitrous oxide obtained pz nitrous oxide. However, nickel oxide hydrate, usually obtained by an exchange reaction or by an electrolytic method and used to prepare nickel oxide, requires very long washing times, often using a vacuum pump.
Предлагаемый способ устран е.т указанные недостатки, сокращает врем промывки и исключает необходимость применени вакуум-насоса .The proposed method eliminates these drawbacks, shortens the washing time and eliminates the need for a vacuum pump.
Отличне предлагаемого способа от известных заключаетс в том, что гидрат закиеи никел предварительно прокаливают при 700- 750 и подвергают легкой отмывке.A better method than that of the proposed method is that the hydrochloric nickel hydrate is preliminarily calcined from 700 to 750 and subjected to easy washing.
В процессе прокаливани кол.тоидпый гидрат закиси никел переходит в кристаллическую закись никел , котора быстро и легко отмываетс от примесей без применени вакуум-насоса.During the calcination process, the colloidal nickel oxide hydrate is converted to crystalline nickel oxide, which is quickly and easily washed from impurities without the use of a vacuum pump.
Пред м е т и з о б р е т е и и PREPARATION AND RESULTS
Способ очистки закиси никел , получаемой из гидрата закиси, отличающийс тем, что гидрат закиси никел предварительно прокаливают при 700-750°, а затем подвергают легкой отмывке.The method of purification of nickel oxide obtained from nitrate hydrate, characterized in that the nickel oxide hydrate is first calcined at 700-750 ° and then subjected to easy washing.
