技術摘要 / Our Technology: |
本發明係提供一種鈦酸鋇陶瓷固溶單晶體及其製造方法。該單晶體中固溶有少量金屬氧化物作為晶粒成長助劑,能以無壓燒結之方法於一大氣壓環境中製造。該方法係於一大氣壓條件中做一階段熱處理或兩階段熱處理即可製造該鈦酸鋇單晶體而不需使用特殊之昂貴設備。藉此,可大量且便宜地製備該鈦酸鋇陶瓷固溶單晶體。
The present invention provides a method of producing the barium titanate solid solution single crystals. The crystalline phase of the single crystal is hexagonal. The method of the present invention, a small quantity of metal oxide is added and dissolved into the barium titanate to form a solid solution. The metal oxides are used as single crystal growth aid; and the barium titanate single crystal can be prepared by using a pressureless sintering process composing of one or two stages of heat treatments that require no special expensive equipments, and thus the method can be used for the mass production of the single crystals.
