Description

Известны сегнетокерамические материалы на основе тнтаната бари , в состав которых входит окись олова, например материал ВК-1.Famous ferroelectric materials based on barium tntanate, which include tin oxide, for example material VK-1.

Предлагаема  сегнетокерамика отличаетс  от известных тем, что в ое состав, кроме титаната бари  и окиси олова, введены небольшие добавки окиси хрома и борной кислоты, Введением этих добавок обеспечиваетс  получение сегнетокерамического материала с более высокой диэлектрической проницаемостью и нелинейностью.The proposed ferroelectric ceramics differs from those known in that, in addition to barium titanate and tin oxide, small additions of chromium oxide and boric acid are introduced. By introducing these additives, a ferroelectric material with a higher dielectric constant and nonlinearity is obtained.

Описываема  сегнетокерамика (условноназванна  ВК-2) имеет следующий химический состав (в вес. %):The described ferroelectric ceramics (conditionally named VK-2) has the following chemical composition (in wt.%):

титанат бари , обоженный при1300 - 96,0 окись олова- 3,5barium titanate, dehydrated at 1300 - 96.0 tin oxide - 3.5

окись хрома- 0,2chromate-0,2

борна  кислота- 0,3boric acid - 0.3

Коэффициент нелинейности материала ВК-2 равен 8The coefficient of nonlinearity of the material VK-2 is equal to 8

(дл  ВК-1 к 4). Величина электрического пол  E.,,ai;e , при которой диэлектрическа  проницаемость достигает максимального значени , составл ет 100-150 (дл  ВК-1 Е„акс 160 - 200 elMM.(for VK-1 to 4). The magnitude of the electric field E. ,, ai; e, at which the dielectric constant reaches its maximum value, is 100-150 (for VK-1 Е, ax 160-200 elMM.

Таким образом, введение в сегнетокерамику указанных добавок повышает диэлектрическую проницаемость и нелинейность без ухудшени  других электрических характеристик.Thus, the introduction of these additives into the ferroelectric ceramics increases the dielectric constant and nonlinearity without deteriorating other electrical characteristics.

Из материала ВК-2 освоено серийное изготовление восьми типов варикондов дл  радиоэлектроники, автоматики и телемеханики, а также сегнетоконденсаторов с высокой удельной емкостью.From material VK-2, mass production of eight types of varicones for radio electronics, automation and telemechanics, as well as high-capacitance ferro-capacitors was mastered.
