چکیده مقاله :

ایتریوم-آلومینیوم-گارنت (YAG، با فرمول شیمیایی Y3Al5O12) نانو کریستال از طریق روش همرسوبی نرمال با استفاده از ایتریا و نیترات آلومینیوم به عنوان مواد اولیه و آمونیوم هیدرژن کربنات (AHC، NH4HCO3) به عنوان عامل رسوبگر سنتز شد. برای بررسی اثر دما و زمان کلسیناسیون پیش ماده حاصل در دمای C° 1100-900 به مدت 2 ساعت و همچنین در دمای C° 1100 در زمان‌های مختلف دیگر (15، 30، 45 و 60 دقیقه) تحت کلسیناسیون قرار گرفت. تغییرات ترکیب فاز و ریزساختار نمونه‌های سنتز شده توسط روش‌های مختلفی از قبیل پراش پرتو ایکس (XRD)، طیف سنجی تبدیل فوریه مادون قرمز (FTIR)، آنالیز حرارتی (TG/DTA)، آنالیز سطح ویژه (BET) و میکروسکوپ الکترونی روبشی گسیل میدانی (FESEM) مورد بررسی قرار گرفتند. فاز مکعبی YAG با متوسط اندازه ذرات nm 33 و میزان سطح ویژه m2/g 30 در دمای C° 1000 تشکیل شد. از طرف دیگر نانو کریستال YAG خالص با کلسینه کردن تنها به مدت 15 دقیقه در دمای C° 1100 نیز حاصل شد. نتایج نشان داد افزایش دمای کلسیناسیون نسبت به زمان اثر بسیار بیش‌تری در افزایش اندازه متوسط کریستال ها و ذرات داشته است.

چکیده انگلیسی:

Nano-crystalline Yttrium aluminum garnet (YAG, Y3Al5O12) were synthesized by normal co-precipitation method using yttria and aluminum nitrates as the starting materials and ammonium hydrogen carbonate (AHC, NH4HCO3) as precipitant. To investigate the effect of temperature and holding time the resultant precursors were calcined at 900-1100 °C for 2 h also at 1100 °C for other durations (15, 30, 45 and 60 min). The evolution of phase composition and micro-structure of the as-synthesized YAG powders were characterized by different techniques such as X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, thermal analyses (TG/DTA), Specific surface area analyses (BET) and field emission electron microscopy (FESEM). The cubic YAG phase with an average grain size of 33 nm and specific surface area of 30 m2/g was completely formed at 1000 °C. In addition, pure YAG nano powders were obtained at 1100 °C in only 15 min calcination. Results showed that compared with increasing holding time, raising of temperature have more intense effect in increasing YAG crystal or particle size.
