This research focuses on recycling silica glass from various silicate glass materials, using liquid-phase deposition (LPD) technique. Recycle of metals and metal oxides is also the target of this research. As an application of recycled silica glasses, thin-film optical waveguides and functional devices were examined. The concentration of residual metal elements in the recycled LPD-SiOF films was three or five orders of magnitude lower than that in the H_2SiF_6 aqueous solution formed from glass bottles. This recycling technique was also applied to cathode lay tube (CRT) glasses. High removal ability for Pb was obtained, however, it was difficult to remove Sb from CRT glasses. The relative dielectric constant for the recycled LPD-SiOF was 3.78 at the measurement frequency 1MHz, and was slightly higher than that for the high quality LPD-SiOF, films (3.74). The transmission loss of thin-film optical waveguides using recycled LPD-SiOF film core was 0.8〜2 dB/cm at the wavelength 632.8 nm. The thermo-optical devices with this waveguide show extinction ratio 8.9 dB and half-wave power 5.89 W. These results are almost the same as those using high quality LPD-SiOF film.

本研究的重点是利用液相沉积（LPD）技术从各种硅酸盐玻璃材料中回收硅玻璃。金属和金属氧化物的回收也是本研究的目标。作为再生二氧化硅玻璃的应用，对薄膜光波导和功能器件进行了研究。回收的LPD-SiOF薄膜中残余金属元素的浓度比玻璃瓶制备的H_2SiF_6水溶液中残余金属元素的浓度低3 ~ 5个数量级。这种回收技术也被应用于阴极铺设管（CRT）玻璃。阴极射线管玻璃对Pb的去除率较高，但对Sb的去除率较低。在1MHz测量频率下，回收LPD-SiOF薄膜的相对介电常数为3.78，略高于优质LPD-SiOF薄膜的相对介电常数3.74。在632.8 nm波长处，采用再生LPD-SiOF膜芯的薄膜光波导的传输损耗为0.8 ~ 2 dB/cm。采用该波导的热光器件的消光比为8.9 dB，半波功率为5.89 W。这些结果与使用高质量的LPD-SiOF薄膜的结果几乎相同。
