초록

SiO2-B2O3-CaO-P2O5계에서 조성이 AFD법에 의해 제조된 유리박막의 열처리 온도와 굴절률에 미치는 영향을 조사하였다. SiO2-B2O3-CaO 삼성분계에서 CaO 함량이 일정할 경우 B2O3 양이 많을수록 융점이 낮아 졌으며, SiO2와 B2O3 함량이 일정할 경우 CaO 양이 많아질수록 융점은 높아졌다. 72.5SiO2-25B2O3-2.5CaO 조성의 융점을 저하시키기 위해 P2O5f를 첨가한 결과，P2O5 첨가량이 증가함에 따라 유리의 용융온도는 낮아졌으며 굴절률은 1.4649 에서 1.4684로 선형척으로 증가하였다. SiO2-B2O3-CaO-P2O5계에서 CaO 와 P2O5 함량이 일정할 경우 SiO2/B2O3의 비가 증가할수록 유리박막의 융점이 낮아졌다.

The effects of the composition on the consolidation temperature and refractive index of the glass thin film fabricated by aerosol flame deposition method in SiO2-B2O3-CaO-P2O5 system were investigated. When the amount of CaO was constant in SiO2-B2O3-CaO system the consolidation temperature of glass thin film decreased with increasing the amount of B2O3. Also, when the amount of SiO2, and B2O3 was constant the consolidation temperature of glass thin film increased with increasing the amount of CaO. P2O5 was added to 72.5SiO2-25B2O3-2.5CaO in order to decrease its consolidation temperature. As the amount of P2O5, increased its consolidation temperature decreased and the refractive index linearly increased from 1.4649 to 1.4684. When the amount of CaO and P2O5 was constant in SiO2-B2O3-CaO-P2O5 system the consolidation temperature of glass thin film decreased with increasing the ratio of SiO2/B2O3.
