Resumo

Scanning electron microscopy and X-ray diffractometry are used to study surface morphology and crystal structure of iron borate FeBO₃ annealed at different temperatures. Temperature limits of the structural stability are determined. It is shown that recrystallization to iron orthoborate Fe₃BO₆ and hematite α-Fe₂O₃ takes places at temperatures of 800–900°C and above 900°C, respectively.
