| Abstract: | In the Y2O3:3Al2O3:4B2O3 system infrared absorption spectroscopy and X-ray diffraction have been used to study the solid-state reactions in the 600–1300°C temperature range. The expected YAl3(BO3)4 formation (whose optimum temperature is at about 1150°C) was proceeded and accompanied by the appearance of YBO3 and Al4B2O9 intermediate phases. At higher temperatures the Al18B4O33 phase was also identified with both methods. Based on these results, some chemical reactions were suggested. |
