Изобретение относитс к технологии получени двуокиси титана сернокислотным способом и преимущественно может быть использовано при получении грубодисперсной двуокиси титана анатазной модификации, при- . мен емой в производстве конденсаторных материалов, силикатных эмалей металлического титанового порошка. Известен способ получени двуоки титана анатазной модификации по сернокислотной схеме, включакадий термогидролиз концентрированных рас воров сульфата титана с концентрацией титана 189-220 г/л по TiO, обработку полученного осадка соедин ни ми кали и фосфора и его прокалк при 15Q-1000°C 1. Получае1 «лй этим способом продукт вл етс высокодисперсным с насыпно массой пор дка 0,35-0,45 г/см и непригоден дл производства конден саторных материалов. кроме того, из вестный процесс включает также oneрацию концентрировани или упарки растворов перед гидролизом, что усл н ет технологический процесс. известен также способ получени двуокиси титана ангьтазной модификации путем гидролиза растворов сульфата титана с концентрацией по двуокиси титана 8U-180 г/л с последующей обработкой Образовавшейс суспензии гидролизата соединени ми кали и фосфора в количестве 0,3 0 ,5 и 0,4-0,8 вес,% соответственно в пересчете на окислы и , фильтрацией ее и прокаливанием отдельного осадка при 800-900°С 2. Однако этот способ также не позвол ет получить продукт, пригодный дл производства конденсаторных материалов . Цель изобретени - получение двуокиси титана анатазной модификации грубодисперсной структуры с насыпной массой 0,65-0,75 г/см, пригодного дл производства конденсаторных материалов. Поставленна цель достигаетс тем, что согласно способу получени двуокиси титана анатазной модификации путем гидролиза растворов сульфата титана с концентрацией по двуокиси титана 80-180 г/л с последующей обработкой образовавшейс суспензии гидролизата соединени ми кали и фосфора, ее фильтрацию и прокаливание Отделенного осадка обработанную указанными соединени ми суспензиюThe invention relates to the technology for producing titanium dioxide by the sulfuric acid method and can advantageously be used in the preparation of coarse titanium dioxide of the anatase modification, with -. variable in the production of capacitor materials, silicate enamels of metallic titanium powder. A known method for producing titanium dioxide of anatase modification according to the sulfuric acid scheme includes thermo hydrolysis of concentrated solutions of titanium sulfate with a titanium concentration of 189-220 g / l by TiO, treatment of the obtained precipitate with potassium and phosphorus compounds and its calcination at 15Q-1000 ° C 1. In this way, the product is highly dispersed with a bulk density of about 0.35-0.45 g / cm and is unsuitable for the production of condenser materials. In addition, the local process also includes one-stage concentration or evaporation of the solutions before hydrolysis, which will condition the process. Also known is a method of producing titanium dioxide with an angiotic modification by hydrolysis of titanium sulphate solutions with a concentration of 8U-180 g / l of titanium dioxide followed by treatment of the resulting hydrolyzate suspension with potassium and phosphorus compounds in an amount of 0.3, 0, 5 and 0.4-0-0, 8 weight,%, respectively, in terms of oxides and, by filtering it and calcining a separate precipitate at 800-900 ° C 2. However, this method also does not allow to obtain a product suitable for the production of capacitor materials. The purpose of the invention is to obtain titanium dioxide anatase modification of a coarse-dispersed structure with a bulk density of 0.65-0.75 g / cm, suitable for the production of capacitor materials. The goal is achieved in that according to the method of producing titanium dioxide of anatase modification by hydrolysis of titanium sulfate solutions with a titanium dioxide concentration of 80-180 g / l followed by treatment of the resulting suspension of the hydrolyzate with potassium and phosphorus compounds, filtering and calcining the separated precipitate treated with these compounds mi suspension
