The results indicate that by simple treatment, the white sandstones can reach a high degree of purity, suitable for different industrial purposes （e.g. manufacture of silicon photovoltaic, crystal, and TV screens, art, and domestic and optical glass）.展开更多
Chemical modification and industrial utilization of lignin based on its structure were reviewed in this paper. And its economic value and significance for the society and environmental protection were also evaluated.

The content of granulated slag ranges from 50% - 60% wt in the glass compositions. The samples were analyzed by DTA , SEM and XRD. The results show that the main crystal phase of the glass- ceramic is β-CaSiO3 , Which is in scattering fiber or column form. The applying properties have also been measured.展开更多
