Abstract
An attempt was made to improve the electrical properties of SnO2-glass composites by dispersing Cu particles in the glass composites. Cu particles were precipitated from matrix glass containing Cu2O by adding LaB6 as a reducing agent. From the experimental results, it was found to be possible to improve the electrical properties of the SnO2-glass composites. However, the electrical properties and the microstructures of the glass composites were supposed to be influenced by the dispersion state as well as the content of a reducing agent. Therefore, it will be necessary to investigate the influential factors on the dispersion of the reducing agent such as particle size and a mixing condition in details for a further improvement.
