| Abstract: | Thermal properties of a recently-developed lead-barium-aluminum plLosphate glass were examined bymeans of differential thermal analysis. The glass exhibits a low melting temperature, relatively low glasstransition and softelting temperatures, and a high coefficient of thermal expansion. The infrared spectraof the glass are characterized by a very weak absorption band in the near-infrared region, the absence of acharacteristic P=O absorption band in the mid-infrared region, and three well-resolved absorption bandsin the far-infrared region indicating the vibrational motion of aluminum, barium and lead ions at theirnetwork sites. |
