Abstract
Abstract The glass forming region of a La2O3-Al2O3-ZrO2 ternary system is determined by containerless processing and the effect of ZrO2 are investigated through a series of colorless and transparent 32La2O3-(68-x)Al2O3-xZrO2 (0≤x≤15) glasses. These glasses show a high thermal stabilities with the glass transition temperature at around 855 °C. With increasing x, the Vickers hardness rises linearly to a maximum hardness of approximately 8.2 GPa, the acid corrosion resistance of glass increases and the glass can resist the corrosion of high concentration acid and alkali. The transmittance of glass reaches 90% in a wide range from visible to infrared region. The corrosion resistance, hardness, thermal and optical properties of 32La2O3-55.5Al2O3-12.5ZrO2 glass are relatively high, which indicates that LaO3/2-AlO3/2-ZrO2 ternary glasses may have the potential to be used as a window material in some harsh environments, such as in the stomach of humans.
