And the activity of dissolved La was directly determined with different La concentra-tions in molten Al at 1023 K. The results were in agreement with that of oxygen concentrationcell EMF determined by oxygen sensors. Some thermodynamic data of Al-La system at1023 K were obtained as follows: △G°_(La)=-175.2 kJ/mol, γ°_(La(s) = 5,85×l0~(-7) ε_(La)~(La)= 28.7, e_(La)~(La)=0.024 Key words:  sensor      activity      La      Al liquid solution      Received:  18 August 1993      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1993/V29/I8/49 1 Colin J.
