Abstract

Density, water resistance, Raman and infrared spectroscopy were used to investigate the change of structural characteristics with the composition of phosphate galss samples made by melting method. The structural abnormality of the density and water resistance were rapidly increased and shown near the 60mol% of $P_2O_5$. This result could be explained by the structural changes owing to the strong shrinkage of glass network by the coordination of DBO(Double-Bonded Oxygen) around $Mg^{2+}$ cations. In addition, it seems that the DBOs coordinating $Mg^{2+}$ cations lose its characteristics of double bonding and resonate with other NBOs(Non-Bonding Oxygen).

용융법으로 제작된 인산염 유리시편의 조성변화에 따른 밀도와 물에 대한 안정성 및 각각의 구조변화를 조사하기 위해 Raman과 적외선 흡수 스펙트럼이 측정되었다. 그 결과 $P_2O_5$가 60mol% 부근에서 밀도와 물에 대한 안정성이 급격히 증가하는 구조적인 이상성을 나타내었다. 이러한 변화는 $Mg^{2+}$ 이온을 중심으로 DBO(Double-Bonded Oxygen)이 배위하면서 유리구조의 강한 수축을 유발시켜 나타난 구조변화에 기인하는 것으로, $Mg^{2+}$ 이온을 배위하고 있는 DBO은 이중결합의 성격을 잃어버리고, 다른 하나의 NBO(Non-Bonding Oxygen)과 함께 공명구조를 이룬다고 생각된다.
