中文摘要
本實驗乃利用嵌入法為製程，先製作磁性相釔鐵柘榴石的單相結晶及鎂磷
酸鹽基礎 玻璃，再製得含有磁性相之玻璃陶瓷。並將製得的玻璃陶瓷作
退火熱處理，進而探討此 種玻璃陶瓷的結構及各種性質。
由實驗結果顯示，以嵌入法所製得的玻璃陶瓷中，嵌入之結晶相確實為釔
鐵柘榴石 單相結晶，釔鐵柘榴石嵌入量最大可至 30 重量百分比率。對
嵌入量 30 重量百分比率 的玻璃陶瓷，在最大外加磁場 14 千奧斯特下
時，具有最高的磁化量每公克 0.399 電 子磁化量單位；且具有最大的
法拉第旋轉角值 每公分 85 度。紅外光穿透率則隨著嵌 入量的增加而
反之下降。
退火熱處理後之玻璃陶瓷，其磁化量、紅外光穿透率及法拉第旋光轉角均
較淬冷玻 璃陶瓷為低。隨著熱處理溫度的提高，磁性相釔鐵柘榴石中之
鐵離子越容易擴散至鎂磷 玻璃基地中，形成三價或二價鐵氧化物，因而
降低了玻璃陶瓷的光學及磁光性質。

ABSTRACT
The glass ceramic of Y3Fe5O12 in Phosphorus-based glass was
synthetized by Incorporation Mathod. The structure and
magnetic properties of the samples for as quenched and
heat treatmented at 300℃, 400℃, 500℃, 600℃ were studied.
From the experimental result, the only crystalline phase in
Phosphorus- based glass was identified as Y3Fe5O12 , the
maximum content is 30 wt%. For the sample with 30 wt% of Y3
Fe5O12 , a maximum magnetization of 0.399 emu/g under a field
of 14 KOe and maximum Faraday rotation angle of 85 dge/cm
were obtained . The transmittance of IR decreases as the
contant of Y3Fe5O12 incresed.
The magnetization, IR transmittance and Faraday rotation angle
of the glass ceramic were decreased after heat treated. By
increasing the temperature of heat-treatment, the
Fe3+ and Fe2+ ions diffuse more easily into the glass
matrix and the iron-oxides was formed, making the magneto-
optical effect of the glass ceramic decreased.
