摘要：

The effect of different calcining temperatures on the lattice constants of the metal oxide semiconductor Nb2O5 was investigated using powder X-ray diffraction technology. It was shown that the crystal structure, lattice constants and crystallite size were changed with the different calcining temperatures. The electrical resistance and the gas-sensing properties of the gas sensor based on Nb2O5 for petrol, i-C4H10, H-2 and C2H5OH gases were different at the different calcining temperatures. The Nb2O5 gas sensor exhibited good sensitivity and selectivity for petrol after calcining at 1000 degreesC. (C) 2001 Elsevier Science B.V. All rights reserved.
