WebThe calculated electronic structure results show that both crystals are large gap insulators with a direct band gap of 4.89 eV for alpha-TCP and 5.25 eV for beta-TCP. Effective … Webdecompose of beta-TCP happened during the generation of silver nanoparticle. However, silver phase disappears while beta-TCP exists in the XRD patterns when the silver/beta-TCP particle was sintered at 1200°C or at 1350°C for 2 h. In contrast, pure beta-TCP transformed to alpha-TCP after being sintered at 1350°
