Abstract
Glass with composition x Quartz Sands+(60-x)P2O5+10BaO+30Na2O (%mol) with (x = 0- 2,5- 10- 5- 10- 15- 20) and 15mol% was tested using melt-quenching technique and ball mill technique to refine quartz sand. Some of the characterization carried out are identify physical properties and structural properties. Characterization using XRD to shows the purity of the high silicate content in quartz sand and shows that QSand-Phosphate glass has an amorphous structure after all samples are mixed. FTIR to show that QSand-Phosphate glass from Hutaginjang has a maximum transmittance absorption band but with different strain widths and heights in vibration absorption as the quartz sand increases. Based on the results of their radiation properties, the glasses in this study has the potential as optical amplifier.
