抄録

An EPR spectroscopy was examined in detail in order to elucidate the role of mechanically induced radicals on the incipient mechanochemical reaction between Ca(OH)₂ and SiO₂. The specific radical species found on separately milled Ca(OH)₂ and SiO₂ disappeared in the case of mixed milling. O^- radicals on Ca(OH)₂ and E′centers on the SiO₂ surface reacted during milling, leading to a precursor of complex oxide with Si-O-Ca bonding. Relative contribution of radical mechanism was compared with those of electron pairs to the complex formation of Si-O-Ca under mechanical stressing.
