Agings and resistances of physical/thermal/optical properties of fine cordierite under the space environment

Detailed material property data of Fine Cordierite in the space environment has not been made publicly available. Therefore, despite its excellent characteristics, there is currently hesitation among groups who actively adopt it in space applications where proven performance is highly valued. In order to address this issue, we have prepared Fine Cordierite test samples, conducted ground tests simulating the space environment using radiation and atomic oxygen exposure and compiled the results into a database. This database includes mechanical properties (bending strength, Young's modulus, and bulk density), thermal properties (coefficient thermal expansion and thermal conductivity), and optical properties (surface accuracy) before and after applying radiation and atomic oxygen exposure. Additionally, the database also includes information of the outgassing from Fine Cordierite in a vacuum environment.
