For this study, the material properties of cordierite ceramics were obtained based on various standards. As a result, cordierite ceramics was found to be superior to glass ceramics in terms of specific stiffness, bending strength, and thermal conductivity. The coefficient of thermal expansion (CTE) indicates a particularly low value near the zero-crossing point at room temperature. Radiation resistance has also been experimentally confirmed. In addition, to assess manufacturability, three mirrors, each was 0.3, 0.7, and 1.3 meters in diameter, were prototyped and verified to be suitable for use as mirrors for visible wavelength. Based on these results, it was revealed that cordierite ceramics have sufficient properties as a mirror substrate for space telescopes and are suitable for lightweight large-diameter mirrors.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1692929640552":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
