| Abstract: | SnO_2-LiZnVO_4 system nanometer powders were prepared by co-precipitation.The influences of sintering processes of SnO_2-LiZnVO_4 nanometer humidity-sensitive material on microstructure,humidity-sensitive characters and capacity characters were studied.The experimental results show that the microstructure and humidity-sensitive characters can be improved by the proper sintering processes.A humidity sensitive material with a fine microstructure of suitable rod-shaped grains,lower resistance at lower humidity and proper humidity sensitivity can be obtained by the proper sintering processes in co-precipitation SnO_2-LiZnVO_4 powders. |
