Description

Изобретение относитс  к способам попученн  конденсаторного материала на основе соединени  LcSjT-i.OThis invention relates to methods for capacitor material based on the LcSjT-i.O compound.

Известен способ получени  конденсаторного материала на основе соецинен;: 1 Т1207 путем осаждени  Lc(,Ae,Ca,Tиз смеси водных растворов нитритов t.o(,A6,Co(и xfjcpKда титана карбонатом аммони  при рН, ра&- ном 7,5-8,0, с последующей термической обработкой гел  при С, затем полученный порошок смешивают с минерали затором. Однако основными недостатками известного способа  вп ютс  недостаточно высокое качествопродукта и сложность технологического процесса.A known method for producing a soicinen-based capacitor material: 1 T1207 by precipitating Lc (, Ae, Ca, Tiz from a mixture of aqueous solutions of nitrite to (, A6, Co (and xfjcpKa titanium by ammonium carbonate at pH, R) , 0, followed by heat treatment of the gel at C, then the resulting powder is mixed with mineral mash. However, the main disadvantages of the known method are the insufficiently high quality of the product and the complexity of the technological process.

С цепью устранени  этих недостатков, осаждению подвергают двухкомпонентную смесь растворов, содержащую хпориц пантана и четыреххпористый титан в эквимолекул ных отношени х, а прокалку полученных садков ведут при 1ООО-11ОО С.With a chain of elimination of these disadvantages, a two-component mixture of solutions containing hporica pantane and tetraporous titanium in equimolecular ratios is deposited, and calcined cages are calcined at 1OOO-11OO C.

Пример. Готов т растворы четыреххлористого титана 3 моп/л и хлорида лантана 1,5 мол/л. Растворы смешивают в эквимолекуп оном отношении и медленно вливают Example. Solutions of titanium tetrachloride 3 mop / l and lanthanum chloride 1.5 mol / l are prepared. The solutions are mixed in equimole between them and slowly pour in.

3 реактор с мешалкой, куда заранее введен аммиачный раствор карбоната аммони , вз тый из расчета на мол рные соотношени .3 a stirred tank reactor where ammonia ammonium carbonate solution was pre-introduced, taken on a molar ratio.

LoiCEj--TiCe :(NH4)2COj:NH OHM4:2--4.LoiCEj - TiCe: (NH4) 2COj: NH OHM4: 2--4.

В этом случае происходит количественное выделение лантана и титана. Осадок отфильтровывают , отьсывают от хпор-ионов ; водой, после чего помещают в холодную печь. Печь нахревают до lOOO-llOO C и осадок выдерживают при этой температуре в течение 6-7 ч. Готовый порошок размешивают с минерализатором (1% .,-), после чего из него спекают конденсаторную керамику. Никакого дополнительного помола материал не требует. Удельна  поверхность порошка составл ет 4ООО см/г. Керамика имеет Е 50, ТКЕ 30-10 , t имеет сглаженный температурный ход.In this case, the quantitative release of lanthanum and titanium occurs. The precipitate is filtered off, otsyvayut from hpor ions; water, then placed in a cold oven. The furnace is covered with lOOO-llOO C and the precipitate is kept at this temperature for 6-7 hours. The finished powder is stirred with a mineralizer (1%, -), after which condenser ceramics is sintered from it. No additional grinding material is required. The specific surface of the powder is 4OOO cm / g. Ceramics has E 50, TKE 30-10, t has a smoothed temperature variation.
