The type of radicals in the silica mineral determined under different temperatures and different microwave power were by examining the intensity distributions of the EPR lines. In EPR spectra, the signals with different intensity distributions were detected. g and A spin-Hamiltonian parameters for these signals were calculated and given in Table 1. These signals are attributed to the 𝐶̇𝐻2, 𝐶̇𝐻3 , 𝐶̇𝐻 , C𝑂2−, 𝑂3−radicals in the glassy structure by comparing with the literature. <br /> </p>}, number={1}, publisher={Atatürk Üniversitesi}
