Description

Изобретение относитс  к получению керамических материалов дл  изготовлени  высокопористых изделий на основе двуокиси кремни , которые могут быть использованы в качестве фильтров, теплоизол ции, катализаторов и адсорбентов или их носителей.The invention relates to the production of ceramic materials for the manufacture of highly porous products based on silica, which can be used as filters, thermal insulation, catalysts and adsorbents or their carriers.

Целью изобретени   вл етс  повьпнение прочности керамики путем снижени интенсивности кристобаллитизации. The aim of the invention is to improve the strength of ceramics by reducing the intensity of cristogalitization.

Шихту готов т сухим смешиванием компонентов. Высокопористые образцы получают пропиткой полимерной матрицы водно-органичесжой суспензией.The mixture is prepared by dry mixing the components. Highly porous samples are obtained by impregnating the polymer matrix with an aqueous-organic suspension.

Составы шихты и прочность получен ной керамики приведены в Ч-абл..The composition of the mixture and the strength of the obtained ceramics are given in H-abl.

Измерение прочности провод т на заготовках, которые спечены в воздушной среде при ПЗОС в течение 0,5 чMeasurement of strength is carried out on blanks that are sintered in air at PZOS for 0.5 h.

Испытание провод т па образцах плотностью 0,5 г/см со средним диаметром  чейки 1,2 мм, имеющих строго параллельные грани.The test was carried out on pa samples with a density of 0.5 g / cm with an average cell diameter of 1.2 mm, having strictly parallel faces.

В табл.2 приведены данные по зависимости прочности при сжатии от плотности материала, полученного сTable 2 presents data on the dependence of compressive strength on the density of the material obtained with

добавлением 1,5% борааморфного,имеющего средний размер  чейки 1,8-2 мм.by adding 1.5% boraamorphic, having an average cell size of 1.8-2 mm.

Материал с добавкой 1,5% бора-после 10 термоциклов по режиму вода - 900 С сохран ет 80% первоначальной прочности.The material with the addition of 1.5% boron — after 10 thermal cycles in the water mode — 900 C retains 80% of the initial strength.
