Sapphire Wafers

Al₂O₃ single crystal (sapphire) exhibits excellent thermal properties, outstanding electrical and dielectric properties, as well as strong chemical corrosion resistance. It features high temperature resistance, good thermal conductivity, high hardness, infrared transmittance and superior chemical stability. It is widely used as high-temperature-resistant infrared window materials, and substrates for III-V nitrides and various epitaxial thin films.To meet the growing demand for blue, violet and white light-emitting diodes (LEDs) and blue laser diodes (LDs), our single crystal company specializes in manufacturing high-quality sapphire crystals and epitaxially polished substrates, providing you with premium single crystals and substrates at competitive prices.In addition to fabricating high-temperature superconducting thin films such as Y-series and La-series, sapphire can also be applied to grow the novel and practical MgB₂ (magnesium diboride) superconducting thin films (note that ordinary single crystal substrates tend to suffer from chemical corrosion during the fabrication of MgB₂ thin films).
