ADS high-density alumina ceramics is a sintered material with a low moisture absorption rate of 0.01% or less. It has many applications in various industries as various structure parts due to its excellent electric insulation, high strength, and abrasion-resistance, etc. Additionally, thanks to its high resistance to acids, alkali, and halogen plasma, it has applications as parts and jigs in the semiconductor and FPD industries.
Various large size parts and complex shapes are also available.
