Abstract
Powder and film of amorphous antimonic acid (Sb2O5⋅nH2O) are prepared by a direct reaction of Sb(O-n-C3H7)3 with H2O2 aqueous solution at 0°C. Thermal decomposition behavior of the powder in air almost coincides with that of the previouly reported one which was prepared by hydrolysis of SbCl5. Electrical conductivity measurement of the film is carried out by using an alternating current complex impedance method. The conductivities at 20°C in the relative humidity range of 0.1 to 1.0 are in the range of 3×10-6 to 1×10-3Ω-1·cm-1, whose values increase with increasing the relative humidity.
