Gallium Oxide Granules Overview
Gallium oxide is an emerging ultra-wide bandgap semiconductor material with the chemical formula Ga₂O₃, typically appearing as a white crystalline powder. With an ultra-wide bandgap of approximately 4.8–4.9 eV, exceptionally high theoretical breakdown field strength, and outstanding Baliga figure, it demonstrates immense potential in next-generation ultra-high-voltage power electronics and deep ultraviolet optoelectronic devices. It is hailed as one of the representative materials of the “fourth-generation semiconductors.”
We offer high-purity β-Ga2O3 Granules and powders, supporting customization for varying purity levels, particle sizes, and crystalline phases (primarily β-phase). Contact us for sample requests.

FAQs
Q1: What advantages does gallium oxide offer compared to silicon carbide and gallium nitride?
A1: Lower cost potential and higher theoretical performance ceiling. It shows promise for achieving lower conduction losses and higher breakdown voltage in ultra-high voltage (>1.2kV) applications. Additionally, large-size single crystals can be grown from the melt, potentially reducing costs.
Q2: What is the “β phase” of gallium oxide?
A2: The most stable crystalline structure phase. β-Ga₂O₃ is the thermodynamically most stable crystal form and the primary phase currently used in power device research and applications, exhibiting excellent electrical properties.
Q3: Is it safe to use gallium oxide Granules ?
A3: Handle according to chemical safety protocols. As an inorganic oxide powder, avoid inhalation and eye contact. Wear protective gear during handling. Refer to the MSDS for specific safety information.
Q4: Why is gallium oxide currently relatively expensive?
A4: It is in the early stages of industrialization. Currently, the preparation of high-purity materials, single crystal growth, and device fabrication processes have not yet achieved full-scale production. The supply chain is in its infancy, leading to higher costs. However, as technology advances, costs are expected to decrease.
