Description
Известен способ получени трехбариевого вольфрамата путем прокаливани смеси ВаСОз и WO;,.A known method for producing three-barium tungstate by calcining a mixture of HACCO and WO ;,.
Недостатком этшо способа вл етс возможность загр знени нсходпых ингредиентов при их изме ,1ьчении и переменгиванип, что отрицательно сказываетс на свойствах изготов, из них веHiecTB .The disadvantage of this method is that it is possible to contaminate the ingredients of the ingredients when they are measured, consumed and reversed, which adversely affects the properties made from them.
В основе предлагаемого способа .теж.ит совместное осаждение BaWO-i и ВаСОз из водных растворов растворимых со.те/г с последу1оп1им прока .7ивание.г полученного осадка.The basis of the proposed method is .teah.the joint precipitation of BaWO-i and VasO3 from aqueous solutions of soluble cos.te / g followed by proc. 7.7g.
Предлагае.мый способ дает воз .гожность по.тучать трехбариевый во.гьфрамат, обладаюпии более выcoKoii гомогенностью и болыней степенью чистоты.The proposed method gives you the opportunity to experience three-bargain water, having more high homogeneity and a greater degree of purity.
Исходны.ми веществами д.п получени трехбариевого вольфрамата служат: (Hi)2WOi (NH,),CO,i и Ba(NO,5)...The starting materials for the preparation of three-barium tungstate are: (Hi) 2WOi (NH), CO, i, and Ba (NO, 5) ...
Формула (NHOAVOi употребл етс условно, так как но ГОСТ вольфрамат а.ммони представл ет собой препарат (NHj) iWsOi 2,5Н2О с содержанием WO.4 от 85 до 89%.The formula (NHOAVOi is conventionally used, since, however, GOST ammonium tungstate is a (NHj) iWsOi 2.5H2O preparation with WO.4 content from 85 to 89%.
Способ осуществл ют следующим образО.т.The method is carried out as follows.
Берхт водный раствор вольфрамовокнслого аммони в соотношении (NH4)2W04:№O 3:10 и водный раствор углекислого ам.мони в том же соотнощении, нагревают .ао 60° и выливают в нагретый до 60° водный раствор азот| окисло1о бари , приггловленный из 1 вес. ч. Ва(КОз)2 и 7 вес. ч. Н-О. При этом вольфрамат бари и тлекис, барий выпадают в оса.и.ок, которьпг отдел ют от раствора азотно1 ис.1ого аммони , вьгсу|ннвают в течение часа при - 100, прессуют и далее прокаливают при 1400°. При прокалива1гии образуетс трехбариевый вольфрамат согласно уравнению: BaWO. - 2ВаСО.1 . Ч- 2С(ЪBercht is an aqueous solution of ammonium tungsten in the ratio (NH4) 2W04: No. O 3:10 and an aqueous solution of ammonium carbonate in the same ratio, heated .ao 60 ° and poured into a water solution heated to 60 ° nitrogen | oxidized barium, gnawed out of 1 wt. h. Ba (Koz) 2 and 7 weight. h. HO In this case, barium tungstate and tlekis, barium fall out in the oxy-oxide mixture, which is separated from the nitrogen and isomeric ammonia solution, boiled out for one hour at -100, pressed and then calcined at 1400 °. When calcined, three barium tungstate is formed according to the equation: BaWO. - 2ВаСО.1. H-2C (b
Выхо.т, готового продукта составл ет 96-98 ii от теоретического.The output of the finished product is 96-98 ii from the theoretical.
изобретени the invention
Способ по.1 чени трехбариевого вольфрамата, о т л и ч а ю ш и Ii с тe, что. с це.тью по.мучени однородного продукта, указанную соль изготовл ют совместным осаждением вольфрамата бари и карбоната бари из водных растворов, с пос .тедую1ним прокаливанием полученного осадка.The method according to 1 of the three-barium tungstate, of which I and Ii with that. With the aid of a homogeneous product, the said salt is made by co-precipitating barium tungstate and barium carbonate from aqueous solutions, followed by calcining the precipitate obtained.
