- Abstract
- Bi-based glass powders with particle size of 34 nm were prepared by high-temperature flame spray pyrolysis. The glass transition temperature (T-g) of the powders was 442 degrees C. Dielectric layers fired at temperatures of 480 and 500 degrees C contained voids, while those fired at temperatures above 540 degrees C had clean surfaces and no voids. The dielectric layers sintered at temperatures of 560 and 580 degrees C had transmittances of 70% in the visible range. Further, it was observed that the dielectric layers formed from the nanosized glass powders obtained from spray solutions containing excess boron had higher transmittances (80% in the visible range at a sintering temperature of 580 degrees C) than the layers formed from spray solutions containing stoichiometric amounts of boron.
