“…[5][6][7] In addition, barium zirconate is a potential material as humidity sensor. 8 Zirconate compounds with high melting points, like BaZrO 3 , are also present in fission products in nuclear industry. The knowledge of the behaviour of fission products and the properties of their compounds is very important for the safety and improvement of nuclear fuels.…”

“…O zirconato de bário de estrutura perovskita é um material refratário com elevado ponto de fusão, baixo coeficiente de expansão térmica, baixa condutividade térmica, boas propriedades mecânicas, estabilidade térmica, e baixa reatividade química com relação a compostos corrosivos [35]. Dopado com cátions trivalentes, é conhecido por absorver prótons na rede cristalina e atuar como condutor protônico em eletrolizadores a vapor, sensores de umidade, bombas de hidrogênio e, particularmente, em SOFCs [4,[35][36][37][38]. O zirconato de bário é geralmente obtido por meio de reações de estado sólido em altas temperaturas, utilizando óxidos de bário e de zircônio como materiais de partida, precedidos pela homogeneização dos pós e redução dos tamanhos de partículas.…”

“…The electrical conduction in the physisorbed water layer is known as the Grotthuss chain reaction. Porous sintered ceramic, at high humidity, permit water condensation within the pore structure, and electrolytic conduction occurs in addition to protonic transport [3,[7][8][9]. The aim of this work is to present the humidity-sensing performance of ZnO 2 -TiO 2 -Ta 2 O 5 ceramic material.…”
