ZMSH Kyropoulos-Grown Sapphire Tubes are precision-engineered cylindrical components grown using the Kyropoulos method. Made from high-purity single crystal Al₂O₃, these tubes exhibit outstanding hardness, thermal conductivity, and optical transparency.
Our sapphire tubes are widely used in semiconductor, aerospace, optical, and chemical industries, especially in high-temperature, high-pressure, and corrosive environments where standard materials such as quartz or alumina may fail.
The Kyropoulos method allows continuous production of custom sapphire geometries—including tubes, rods, and sleeves—with excellent dimensional accuracy, making them ideal for thermocouple protection, laser systems, and optical inspection devices.
