Résumé

Electron radiation damages to dicalcium silicate (Ca₂SiO₄) and tricalcium silicate (Ca₃SiO₅) are reported for the first time in this paper. With increasing flux, between 2.7 × 10¹⁷ and 2.2 × 10²² e^- cm^-2 s^-1, decomposition into nanodomains of crystalline CaO plus an amorphous silica rich phase is first observed for both silicates, then amorphization at higher flux always for both silicates, and finally hole drilling but only for Ca₃SiO₅. These structural modifications are accompanied by a net reduction of Ca content under the electron beam depending on the silicate species. These radiation effects occur for values of flux and dose larger than in previously studied orthosilicates (like olivines), and much larger than in all tectosilicates.
