| Abstract: | By the methods of diffrent thermal analysis, X-ray diffraction . infrared absorption spectra. Raman scattering spectra and electron microscopy, the Cr2O3-free andCr2O3-containing PbO -ZnO-B2O3-SiO2 system glasses are studied.The purpose of the present work is to chracterize the effect on glasses crystallization ofadditive Cr2O3 and heattreatment. Crystal phases, structure and morphologh changes arestudied respectively.The mechanism of phase sepration and crystallization is presented. When Cr2O3 contentis low. It acts as a nucleating agent. when Cr2O3 content is higher, its main effect is participating in the forming of crystal phases. As raising the Cr2O3 content. the traction of crystalphases that include Crclement increases. Proper heat treatment assists in the forming ofglass -ceramics. |
