99.99% Alumina Ceramic
99.99% alumina ceramic is centered on an ultra-high-purity alumina matrix, achieving atomic-level dense structures through ultra-high-temperature sintering processes. Its hardness rivals that of natural single-crystal corundum and exhibits ultra-high-temperature stability in extreme inert or vacuum environments. The material possesses zero-porosity impermeability, resisting erosion from molten metals, plasma, and highly corrosive media, while boasting ultra-low dielectric loss and sub-nanometer surface smoothness, making it ideal for high-precision optical and electronic device fabrication. Its unique biocompatibility and non-magnetic hysteresis effects enable critical applications in deep-space probe radiation shielding layers and superconducting system insulation components. It also plays an irreplaceable role in quantum technology, semiconductor lithography, and other cutting-edge fields, representing the pinnacle of industrial ceramic performance and manufacturing technology.
FAQ
