Description
СПОСОБ ПОЛУЧЕНИЯ ГИДРОСИЛИКАТА ЦЕРИЯMETHOD OF OBTAINING CERIUM HYDROSILICATE
Изобретение относитс к способам получени гидросиликата цери , который может быть использован в квантовой электронике, радиокерамике и дл получени специального огнеупорного материала.The invention relates to methods for producing cerium hydrosilicate, which can be used in quantum electronics, radio ceramics, and for producing special refractory material.
Известен способ получени гидросиликата цери путем спекани окиси цери и кремнезема нри 1200-1600°С. Однако такой способ сложен из-за высокой температуры проведени процесса и больших энергозатрат.A known method for producing cerium hydrosilicate by sintering cerium oxide and silica at 1200-1600 ° C. However, this method is complicated due to the high temperature of the process and high energy consumption.
С целью упрощени процесса, предлагаетс синтез вести из водных растворов силиката натри и четырехвалентного сульфата цери при соотношении NagSiO.} и Се(804)2, равном 0,1-0,3, црн 15-35 0.In order to simplify the process, it is proposed to synthesize lead from aqueous solutions of sodium silicate and tetravalent cerium sulfate at a ratio of NagSiO.} And Ce (804) 2, 0.1-0.3, crn 15-35 0.
Пример. К 40 мл 0,9 м раствора NaSiOn добавл ют 3,68 мл 0,95 м раствора Се(804)2, перемешивают в течение 15-20 мин и оставл ют до установлени равновеси при 20°С.Example. 3.68 ml of 0.95 m Ce (804) 2 solution is added to 40 ml of 0.9 m solution of NaSiOn, stirred for 15-20 min and left to establish equilibrium at 20 ° C.
Получают осадок состава Ce02-2Si02-nH2O. Полученный осадок отдел ют от раствора фильтрацией и высушивают на воздухе.A precipitate of composition Ce02-2Si02-nH2O is obtained. The precipitate obtained is separated from the solution by filtration and dried in air.
Предмет изобретени Subject invention
Способ получени гидросиликата цери , отличающийс тем, что, с целью упрощени процесса , синтез ведут из водных растворов силиката натри и четырехвалентного сульфата цери при соотношении Ма251Оз и Се(864)2, равном 0,1-0,3, при 15-35°С.A method for producing cerium hydrosilicate, characterized in that, in order to simplify the process, the synthesis is carried out from aqueous solutions of sodium silicate and tetravalent cerium sulfate at a ratio of 2525 Oz and Ce (864) 2 equal to 0.1-0.3, at 15-35 ° WITH.
