“…In the synthesis of the (Ca 1Àx Cu x )TiO 3 microcrystals using basic conditions (KOH [6 M]), initially, occurs the hydrolysis of Ca 2þ , Cu 2þ and Ti 4þ ions giving rise to the Ca(OH) 2 , Cu(OH) 2 and TiO(OH) 2 precipitates ( Fig. 11(a)).…”

“…Crystalline ceramics mainly perovskite-type mixed metal oxide of chemical formula (ABO 3 ) have attracted attention over the years due to their physical and chemical properties, which can be changed by easy substitution in both the A and B-sites with several compositions [1,2]. In particular, titanium-based perovskite oxides with formula ATiO 3 (A ¼ Pb, Sr, Ba, Zn, Ni, or Fe) presents outstanding potential in electronics [3], gas sensors [4], catalysis [5], memory devices [6], magnetic material [7], and so on.…”

“…Dentre as aplicações mais contundentes, cita-se a possível utilização destes sólidos como catalisadores de células á combustível, juntamente com um oxidante, gerando um potencial eletroquímico a partir de cargas gasosas [19], já que a temperatura não afetaria os seus sítios ativos. Outras utilizações referem-se a óxidos com estrutura perovskita (NiTiO 3 ) [20], onde a sua aplicabilidade como sensores de umidade é bastante citada. O titanato de bário (BaTiO 3 ) possui funcionalidade efi cientemente comprovada como sensor de umidade [21] por apresentar alta constante dielétrica [22]; portanto, é plausível que TiNiO 3 também apresente propriedades semelhantes em termos da condutividade elétrica, pois a constante dielétrica de compósitos contendo níquel também é bastante elevada [23].…”

“…Zn-doped NiFe 2 O 4 [12], NiMoO 4 [13], Ni x Mn 3−x O 4 [14], Ni x Zn 1−x Fe 2 O 4 [15], Ni 1−x Co x Fe 2 O 4 [16] are some examples of the mentioned materials where A site is occupied by Ni cations. Among them, nickel titanate has been investigated as a tribological coating to reduce friction and wear at high temperature [17][18][19][20].…”
