摘　　要：用差热分析和热机械分析研究了一种新发展的铅-钡-铝磷酸盐玻璃的热性质，表明这种玻璃的熔化温度低，转变温度和软化温度也较低，热膨胀系数大．这种玻璃的红外光谱的特点：在近红外区有一很弱的水分吸收带，在中红外区没有P＝0特征吸收带，在远红外区的三个吸收带，指示玻璃中三种金属阳离子在它们的氧笼中的振动．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.
