Alumina 99% is a ceramic material with Al2O3 as the main crystal phase. SENCER PRECISION CERAMICS can produce ceramic products with an alumina content of 96% to 99.8%. Alumina is also called Al2O3 in the industry, a melting point of 2050°C, and a boiling point of 2980°C. Alumina 99% ceramic parts have 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 ceramics have high mechanical strength, high volume resistivity, good electrical insulation properties, high lightness, and wear resistance. The advanced ceramics made by alumina 99% could be white or ivory, and different molding and sintering methods can be selected according to different uses of customers. The main pressing is usually Dry Pressing, Hot Pressing, Isostatic Pressing, and Injection Molding depends on the structure of the ceramic parts.
