Improvement Method of Crystalline Particles Characteristics Using Inner Seed Crystals 結晶粒子群特性を改善するための内部種結晶利用法の開発

(要約)結晶粒子群の特性改善に向けて、結晶化の推進力を考慮した内部種結晶の利用法について検討した。初期結晶に着目し、内部種結晶として機能させることを試みたところ、迅速な推進力の消費と望まれない結晶化現象の抑制が実現でき、特性が改善した結晶粒子群を得ることに成功した。結論として、内部種結晶が結晶化現象に及ぼす影響の解明とその利用法が示された。The utilization of internal seed crystals, considering the driving force of crystallization, was investigated as a method to improve the characteristics of crystalline particle groups. By focusing on the initial crystals and attempting to make them function as internal seed crystals, rapid consumption of the driving force and suppression of undesirable crystallization phenomena were successfully achieved, leading to crystalline particle groups with improved characteristics. In conclusion, this study elucidates the influence of internal seed crystals on the crystallization phenomenon and demonstrates their potential application.
