Gas-Thermal Spraying Synthesis of β-GaO Luminescent Ceramics.

This paper presents the initial results of the synthesis of β-GaO luminescent ceramics via plasma gas-thermal spraying synthesis, where low-temperature plasma of an argon and nitrogen mixture was employed. A direct current electric arc generator of high-enthalpy plasma jet with a self-aligning arc length and an expanding channel of an output electrode served as a plasma source. The feedstock material consisted of a polydisperse powder of monocrystalline β-GaO with particle sizes ranging from 5 to 50 μm.
