The results show that the density of glass, glass transition temperature and thermal expansion coefficient increase with the increase of yttria content, and the chemical durability decreases with the increase of yttria content. The bend strength of glass increases from 53.52 MPa to 109.65 MPa when 1.80% Y2O3 is added into glass. However, with the content of yttria further increases to 6.84%, the bend strength is suspended about 110 MPa. Y2O3 acting as network modifies in the structure and makes the island-shape network unit repolymerization by the bonding of Ge-O-Y because of the decrease of non-bridge oxygens and strengthening of glass network structure.

结果表明：该系统玻璃的密度、玻璃转变温度和热膨胀系数随氧化钇含量的增加而升高，玻璃的化学稳定性随氧化钇含量的增加而下降；在玻璃中加入1.80%氧化钇后，玻璃的抗弯强度值由53.52 MPa增至109.65 MPa；继续增大氧化钇的含量至6.84%时，玻璃的抗弯强度维持在110 MPa左右；氧化钇的加入减少玻璃网络结构中非桥氧数量，使孤立的岛状网络单元重新聚合，增强玻璃的网络结构。
