Abstract
"The purpose of this work was to investigate the properties of Y₂O₃-Al₂O₃-SiO₂-MxOy glasses. Many MxOy components were tested, but TiO₂ and B₂O₃ proved the most interesting. Glasses containing 5 to 25 wt % TiO₂ were melted and found to have improved chemical durability and a higher refractive index and density than the eutectic Y₂O₃-Al₂O₃-SiO₂ starting glass. These glasses could be crystallized to form an opaque glass ceramic. Glasses containing B₂O₃ were formed by exchanging SiO₂ with B₂O₃ while holding the Y₂O₃ and Al₂O₃ content constant. The density, hardness, refractive index, transformation temperature, softening temperature and chemical durability decreased with increasing B₂O₃ content, while the thermal expansion coefficient increased"--Abstract, page 1.
