AbstractIn the present study we synthesized conductive nanoscale [Ca24Al28O64](4+) (4e(-)) (hereafter denoted as C(12)A(7):e(-)) material, and reduced graphene oxide (rGO) was produced, which was unexpected; graphene oxide was removed after melting the sample. The conductivity of C(12)A(7):e(-) composites synthesized at 1550 degrees C was 1.25 S cm(-1), and the electron concentration was 5.5 x 10(19) cm(-3). The estimated BET specific surface area of the highly conductive sample was 20 m(2) g(-1). Pristine C(12)A(7):e(-) electride was obtained by melting the composite powder, but the nano size of C(12)A(7):e(-) particles could not be preserved; the value of conductivity was similar to 28 S cm(-1), electron concentration was similar to 1.9 x 10(21) cm(-3), and mass density was 93%. For C(12)A(7-x)V(x):e(-), where x = 0.25 to 1, the conductivity improved to a maximum value of 40 S cm(-1), and the electron density improved to similar to 2.2 x 10(21) cm(-3); this enhancement in conductivity was also proposed by a theoretical study but lacked any associated experimental support.
