| Abstract: | The effects of irradiation on the coefficient of thermal expansion (CTE), the density, and the elastic moduli of low-CTE materials such as amorphous SiO2, ultra-low-expansion glass, β-SiC, Astrositall, and Zerodur were surveyed. It was found that the properties of all of these materials were affected by radiation exposures up to 2 × 109 rd; SiO2 and SiC were the most radiation-resistant of the materials studied. |
