Between high silica glasses and normal glasses such as soda-lime glasses, there should be special glasses having a fictive temperature-independent specific volume. These glasses would exhibit no changes in volume, density, refractive index, ionic diffusion, electric conductivity, bulk modulus and hardness during the heat-treatment. It is the objective of the proposed research to produce such glasses and investigate their unique properties.The glasses to be developed in the proposed research would be useful in producing the non-shrinkage flat panel displays needed for large flat TVs and computers. They would also be useful in clarifying the mechanisms of strengthening of glasses and radiation damage of glasses.

在高硅玻璃和普通玻璃（例如钠钙玻璃）之间，应该存在具有假想的与温度无关的比容的特殊玻璃。这些玻璃在热处理过程中不会表现出体积、密度、折射率、离子扩散、电导率、体积模量和硬度的变化。本研究的目的是生产这种玻璃并研究其独特的性能。本研究中开发的玻璃可用于生产大型平板电视和计算机所需的无收缩平板显示器。它们还有助于阐明玻璃的强化机制和玻璃的辐射损伤。
