Özet

The elemental analysis of dolomite [CaMg(CO3)] doped glasses encoded DG10, DG20, DG30 and DG40 with different compositions is tested using Energy Dispersive X-ray (EDX) technique. Next, the surface morphology of fabricated glasses was investigated with scanning electron microscopy (SEM). On the other hand, the optical properties of fabricated the Dolomite additive were evaluated along the wavelength ranged from 300 to 900 nm. At last, nuclear radiation shielding properties of dolomite glasses were determined for gamma-rays. It is observed from the optical absorption spectra that the surface becomes smooth with no agglomerations with Dolomite%30 and %40. In addition, the results showed that Dolomite additive improves the gamma protecting capacity of lithium borate glasses. As a result, it can be referred that a glass sample with the highest Dolomite additive encoded DG40 has better shielding efficiency in terms of radiation shielding.
