Product detail
Alumina ceramic, also known as Al2O3 or aluminum oxide ceramic, finds extensive application in high-temperature environments due to its excellent resistance to elevated temperatures. It possesses remarkable thermal stability, withstanding temperatures up to 1800℃. In addition to its stable chemical properties, it offers high mechanical strength and electrical insulation capabilities. Alumina ceramic is commonly used for manufacturing ceramic tubes for high-temperature furnaces, closed-end ceramic tubes or multi-hole insulating rods for thermocouples, and square ceramic tubes for corona electrodes.
At Mascera, we utilize extrusion molding technology to produce ceramic tubes up to 2000mm in length. Custom sizing options are available, and we encourage you to reach out to us with your specific requirements.
