Abstract	Morphology controlled α-GaO(OH) particles have been synthesized via precipitation method which allows the tuning of relative growth rates of crystal facets. The effects of alkali addition rate and the type of alkali on the growth rates of the crystal facets during hydrolysis were also investigated. XRD and TG analysis confirmed that there was a phase transition from GaO(OH) to Ga 2 O 3 when precursor sample was calcined to 750C. The single phase α-Ga 2 O 3 was obtained after thermal treatment of NaOH precipitated precursor, while β-Ga 2 O 3 was formed when the urea or NH 4 OH precipitated precursor was calcinated. Furthermore, the thermal, spectral, and photocatalytic properties connected to the crystal structure and morphology were discussed.
