XANES (Si L3 and O K) study confirmed the formation of an amorphous SiO2 layer at the ceramic electrolyte-NiO interface during the high-temp. (1000°) oxidn. of Ni in an electrochem. cell contg. ceramic (ZrO2:Y2O3) electrolyte. The local structure of the glassy layer is described in terms of SiO4 tetrahedral clusters with short-range order.

The local structure of the glassy layer is described in terms of SiO4 tetrahedral clusters with short-range order.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
