Magnesium gallate (MgGa₂O₄) is a ceramic compound formed by combining magnesium (Mg), gallium (Ga), and oxygen (O). It crystallizes in the spinel structure, where Mg²⁺ ions occupy the tetrahedral sites and Ga³⁺ ions fill the octahedral sites. This structure contributes to its high thermal and chemical stability, making it ideal for various high-temperature applications.
Crystal Structure: Magnesium gallate has a cubic spinel crystal structure, with the space group Fd-3m. This structure is known for its stability, which enables high resistance to deformation and high-temperature stability.
Density: It typically has a density of around 4.6 g/cm³, which is relatively high for spinel-type materials.
Thermal Expansion and Stability: MgGa₂O₄ exhibits low thermal expansion and high thermal stability, making it a candidate for high-temperature ceramics.
Optical Properties: Magnesium gallate is transparent in the visible and near-infrared (IR) ranges. Its wide bandgap (typically around 5 eV) renders it an insulating material and gives it a high degree of transparency in these regions.
Optoelectronics: Its luminescent and optical properties make it useful in LED phosphors and display technologies, particularly for producing blue and green light.
High-Temperature Ceramics: The thermal and chemical stability of MgGa₂O₄ spinel makes it suitable for use in high-temperature ceramic components, especially those exposed to harsh conditions.
Catalysis: Due to its structural stability and high surface area (especially when synthesized as nanocrystals), magnesium gallate may serve as a catalyst or catalyst support in chemical reactions.
Coatings and Liners: The material’s corrosion and thermal stability make it useful as a coating in furnaces, reactors, and other high-temperature environments.
Transparent Ceramic Windows: The optical transparency of MgGa₂O₄ spinels makes them potential candidates for transparent ceramic windows or covers in optical and IR applications.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
