Description
Двуокись титана, несмотр на высокую диэлектрическую проницаемость-120 (чем она выгодно отличаетс от обычных диэлектриков, примен емых в радиопромышленности ), не может быть использована .дл изготовлени керамических изделий вследствие высокой температуры спекани .Titanium dioxide, in spite of the high dielectric constant-120 (which compares favorably with conventional dielectrics used in the radio industry), cannot be used to manufacture ceramic products due to the high sintering temperature.
Предметом изобретени вл етс способ изготовлени керамических изделий на базе двуокиси титана тюсредством добавлени к нему таких компонентов, которые снижали бы температуру спекани с 1800 до 1200°С и ниже.The subject of the invention is a method for the manufacture of ceramic products based on titanium dioxide by adding means to it that would reduce the sintering temperature from 1,800 to 1,200 ° C and below.
Таким компонентом вл етс фосфат свинца РЬз(РО4)2, приготовленный :из .водных растворов дважды перекристаллизова«ных уксуснокислого свинца и трехзамещенного фосфата аммони или сплавлением углекислого свинца с монофосфатом аммони .Such a component is lead phosphate РЬз (РО4) 2, prepared: from aqueous solutions of double recrystallization of lead acetate acetate and trisubstituted ammonium phosphate or by fusing lead carbonate with ammonium monophosphate.
Известны способы изготовлени керамической массы на базе спекающейс пр-и температуре 1300- 1500° двуокиси титана (рутила) того же назначени с другими добавками , обеспечивающими диэлектрические свойства издели .There are known methods for producing ceramic mass on the basis of a sintered area and a temperature of 1300-100 ° C titanium dioxide (rutile) of the same purpose with other additives that provide the dielectric properties of the product.
Особенность предлагаемого способа заключаетс в том, что дл получени диэлектрической керамики В массу вводитс только один добавочный компонент-фосфат свинца , обеспечивающий как понижение температуры спекани ее до 1100° с обычной дл рутила 1800°, так и прочность, при сохранении за изделием необходимых диэлектрических свойств.The peculiarity of the proposed method is that in order to obtain dielectric ceramics, only one additional lead phosphate component is added to the mass, which provides both a decrease in its sintering temperature to 1100 ° C and 1800 ° typical for rutile, and the necessary dielectric properties .
Рассчитанные количества порошкообразных двуокиси титана и фосфата свинца отвещиваютс на весах, тщательно перемешиваютс и растираютс в агатовой ступке, прессуютс в сухом СОСТОЯНИЙ в таблетки под давлением 250-500 кг/см и обжигаютс в электрической печи при температуре 1100-1200, в зависимости от содержани фосфата свинца. При 15% фосфата свинца спекание достигаетс уже при 1100°. Приуменьшении содержани фосфата температура спекани возрастает до 1200°, при увеличении-снижаетс до 1000° и ниже. № 77972Предмет изобретени Способ изготовлени керамических изделий на базе двуокиси титана 2 - ( рутила), отличающийс тем, что дл понижени температуры. спекани рутиловой массы в неедобавл ют фосфат свинца.The calculated amounts of powdered titanium dioxide and lead phosphate are weighed, thoroughly mixed and ground in an agate mortar, pressed in a dry CONDITION into tablets under a pressure of 250-500 kg / cm and burned in an electric furnace at a temperature of 1100-1200, depending on the phosphate content lead. With 15% lead phosphate, sintering is already achieved at 1100 °. By reducing the phosphate content, the sintering temperature rises to 1200 °, with an increase — it decreases to 1000 ° and below. No. 77972 of the invention. A method for producing ceramic products based on titanium dioxide 2 - (rutile), characterized in that it lowers the temperature. sintering the rutile mass in the lead phosphate deaddate.
