Cl-2 gas sensor using Na+ conducting solid electrolyte
A composite Na+ conductor of polycrystalline NASICON mixed with a glassy Na2O-Al2O3-4SiO(2) (40wt%) was used in Cl-2 gas sensor. The probe using the composite electrolyte and a RuO2+NaCl (1:1) measuring electrode gave rapid EMF changes even for sub-ppm level of Cl-2 gas concentration (below 6 ppm).
