Abstract

<B>"CONDUTORES IÈNICOS DO TIPO BIMEVOX OBTIDOS PELO PROCESSO DE FUSãO"<D> Refere-se o presente invento a uma composição de uma nova família de materiais condutores iónicos do tipo BIMEVOX obtidos pelo processo de fusão (condutores de íons oxigênio) baseada no óxido de bismuto e de vanádio, cujo material apresenta características completamente diferentes dos eletrólitos sólidos condutores de oxigênio atuais que são uma alta condutividade iónica para íons oxigênio a temperaturas relativamente baixas de operação quando comparada aos materiais com a estrutura da fluorita como a zircónia e céria, obteve-se a fase Bi~ 4~V~ 2~O~ 11~ (principal responsável pela condutividade iónica do sistema) com um íon aditivo adequado por um novo processo de síntese de pós cerâmicos que conduziu a amostras policristalinas cerâmicas de alta densidade (acima de 90% do valor da densidade teórica) e elevada condutividade iónica.<B> "IONIC CONDUCTORS OF THE BIMEVOX TYPE OBTAINED BY THE FUSION PROCESS" <D> The present invention relates to a composition of a new family of ionic conductive materials of the BIMEVOX type obtained by the fusion process (oxygen ion conductors) based on in bismuth and vanadium oxide, whose material has completely different characteristics from today's solid oxygen-conducting electrolytes which are high ionic conductivity for oxygen ions at relatively low operating temperatures when compared to materials with fluorite structure such as zirconia and ceria , the Bi ~ 4 ~ V ~ 2 ~ O ~ 11 ~ phase (main responsible for the ionic conductivity of the system) was obtained with an additive ion suitable for a new ceramic powder synthesis process that led to high density polycrystalline ceramic samples (above 90% of the theoretical density value) and high ionic conductivity.
