Objectives. To examine the general principles and recent advances in the synthesis of high-purity and high-homogeneity barium titanate powders in the manufacture of electronic components.

Results

Results. The main publications regarding the synthesis of barium titanate powder, including the works of recent years, were analyzed. The technological advantages and disadvantages of various synthesis methods were identified. Groups of methods based on solid-state interaction of reagents and methods of “wet chemistry” were also considered. The possibilities of producing barium titanate particles of non-isometric shapes for creating textured ceramics were discussed separately.

Conclusions

Conclusions. Barium titanate is a well-known ferroelectric with a high dielectric constant and low dielectric loss. It is used as a component in ceramic electronic products, for example, capacitors, memory devices, optoelectronic devices, and piezoelectric transducers. The possibilities of producing functional ceramics based on barium titanate powder largely depend on its state and morphological characteristics, determined during the synthesis stage. The most important factors affecting the functional characteristics of ceramics are the purity and morphology of the powder raw materials used.

Цели

Цели. Проанализировать общие принципы и последние достижения в области синтеза порошков титаната бария высокой чистоты и гомогенности для изготовления электронных компонентов.

Результаты

Результаты. Рассмотрены основные публикации о синтезе порошка титаната бария, включая работы последних лет, отмечены достоинства и недостатки различных методов синтеза с технологической точки зрения. Проанализированы группы методов, основанные на твердофазном взаимодействии реагентов, и методы «мокрой химии». Отдельно обсуждены возможности получения частиц титаната бария неизометричной формы, предназначенные для создания текстурированной керамики.

Выводы

Выводы. Титанат бария является широко известным сегнетоэлектриком с высокой диэлектрической проницаемостью и низким значением диэлектрических потерь и применяется в качестве компонента керамических изделий электроники, например, для конденсаторов, запоминающих устройств, оптоэлектронных устройств, пьезоэлектрических преобразователей. Возможности производства функциональной керамики на основе порошка титаната бария во многом зависят от его фазовых и морфологических характеристик, которые определяются на этапе синтеза. Одними из важнейших факторов, влияющих на функциональные характеристики керамики, выступают чистота и морфология используемого порошкового сырья.
