“…Sample S6 shows good ionic conductivity of 0.017 S cm -1 compared to the undoped sample S0. Sample S2 containing equal amount of the two dopants has also a conductivity of 0.01 Scm -1 which is only slightly higher than the undoped sample but comparable to that reported by A. Pons et al [45]. The activation energies of the samples calculated from the Arrhenius plot are summarized in Table 4.…”

“…Ionic surfactants, such as decyltrimethylammonium bromide (CH 3 (CH 2 ) 9 N(CH 3 ) 3 (Br), C(10)TAB), hexadecyltrimethylammonium bromide (CH 3 (CH 2 ) 15 N (Br)(CH 3 ) 3 , C(16)TAB), as well as nonionic surfactant, can be used to control the pore (pore size and volume) and surface characteristics of mesoporous apatite materials under maintained pH [153]. The porosity also affects electrical properties of oxyapatites (Chapter 5) [154], [155], [156].…”

“…Entre estes, destaca-se o YSZ (ZrO2 estabilizado com Y2O3) (4) . Este, por sua vez, possui condutividade iônica de 0,1 S/cm em temperatura acima de 1000°C (18) Materiais como CeO2, óxido de cério, e este dopado com Gd (gadolínio) -GDC, Sm (samário) -SDC, possuem condutividades iônicas em 750°C, similares ao YSZ em 1000°C e em altas pressões parciais de oxigênio (42) .…”

“…YSZ é o material mais utilizado como eletrólito em SOFCs. Isto se deve ao fato de que o mesmo possui alta condutividade iônica em elevadas temperaturas (800 a 1000°C), insignificante condução eletrônica, boa estabilidade química em uma ampla faixa de pressões parciais, elevada resistência mecânica e flexibilidade na utilização de combustíveis (18,46,47) .…”
