Product Details:

Alumina ceramic tube is made of a ceramic material with Al2O3 as the main crystal phase. SENCER PRECISION CERAMICS can produce ceramic tubes with an alumina content of 99% to 99.8%. The alumina has a compact structure, low activity, and high-temperature stability. The electrical properties are the best, with good mechanical properties, with a Mohs hardness of 9. With their excellent wear resistance, heat resistance, corrosion resistance, and good chemical stability, alumina ceramic plates are widely applied in numerous industries.
