01 The increase in gallium oxide market share during the forecast period is related to the growing semiconductor industry and increasing demand for these transistors. The global market is experiencing growth due to the rising need for high-performance power electronics and energy-efficient products. It is also known as gallium sesquioxide (Ga2O3), and can be found in the market as a white powder consisting of rod-shaped crystals, with the β-phase being the most prevalent crystalline form. Ga2O3 is utilized in various applications, including phosphors, cathodes for solid oxide fuel cells, GGG (gallium gadolinium garnets) crystals, piezoelectric crystals, and sputtering targets for GIZO or IGZO materials. This semiconductor material has a wider bandgap than gallium nitride, silicon, and silicon carbide. Due to its extensive bandgap, it is increasingly becoming a preferred material for developing solar-blind photodetectors and power electronic devices, particularly in demanding environmental conditions.
April 2026 Indium Corporation secured a USD 3.2 million grant from the U.S. Department of Energy to develop and commercialize a domestic process for recovering high-purity gallium from manufacturing by-products. The project will be conducted at the company’s Rome, New York, facility and is expected to scale to a production-ready system capable of producing at least one metric ton of 4N-grade gallium annually. Indium Corporation supplies gallium oxide and other gallium compounds to semiconductor and electronics manufacturers.
March 2026 Nagoya University and its spinout company NU-Rei Co., Ltd. advanced six gallium oxide thin-film growth technologies toward commercialization. The developments included the first reported heteroepitaxial growth of gallium oxide on lower-cost silicon substrates and a new high-density oxygen radical source designed to improve Ga₂O₃ growth rates for industrial MBE and PVD manufacturing processes.
February 2026 Novel Crystal Technology began sample shipments of 150 mm gallium oxide substrates for next-generation power-semiconductor development. The larger-diameter substrates are intended to support higher device productivity, reduce manufacturing costs and accelerate the transition of Ga₂O₃ power devices from research-scale production toward commercial fabrication.
October 2025 The U.S. and Australian governments agreed to support Alcoa’s proposed gallium production facility beside its alumina refinery in Western Australia. Australia committed up to USD 200 million in concessional equity financing, while both governments obtained potential offtake rights. The proposed facility could eventually supply approximately 10% of global gallium requirements, strengthening feedstock availability for gallium oxide and other compound-semiconductor materials.
