Alumina Rod Description
Alumina Rod, made of high-purity aluminum oxide (Al2O3) ceramic, is a fine ceramic material widely used in various industries. Alumina rods exhibit superb performance in electrical insulation, high chemical resistance, and low thermal expansion, making them essential in many high-demand applications.
High-purity alumina products are excellent for making parts for CVD, ion implants, photolithography, and semiconductor parts. In traditional industries, alumina ceramics are ideal for products such as injector tubes, gas nozzles, and insulators.
