Phase analysis of solid-state synthesized lithium iron phosphate samples was performed, using Raman spectroscopy. The effect of the probing laser-induced decay of LiFePO4 with the formation of the Fe2O3 phase is demonstrated. Statistical analysis of a series of measurements allowed us to assume the critical nature of this effect.
