摘要：

Microwave processing is an attractive alternative to conventional furnace treatment for sintering of TiO2 nanostructured thin films. When heated with 2.45-GHz microwaves, it was found that conducting glass cracked when a temperature above similar to 200 degrees C was reached. Coating a similar to 20-mu m-thick film of nanostructured TiO2 on the transparent conducting oxide (TCO) glass (using a commercially available powder) raised the temperature at which cracking occurred to similar to 400 degrees C. When a sol-gel method was used to produce TiO2, difficulties were encountered in the production of -10-mu m-thick films, including cracking of films during drying. (c) 2004 Elsevier B.V.
