Alumina ceramics is a ceramic material with Al2O3 as the main crystal phase. SENCERAMCS can produce ceramic products with an alumina content of 96% 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. Alumina 99.8% ceramics have high mechanical strength, high volume resistivity, good electrical insulation properties, high lightness, and wear resistance. A series of anti-oxidation properties are widely used in structural parts and functional device ceramic parts, such as wear-resistant and corrosion-resistant parts used in the mechanical and chemical fields; crucibles, protective tubes, refractory materials used in the metallurgical industry; substrates, insulators, Porcelain parts for the electronics industry, such as radomes, microwave electrolytes, etc.
