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.
