Technical ceramics are materials with hardness, toughness, wear resistance, thermal conductivity and high strength properties.
Industries such as semiconductor, energy, space, defense, consumer electronics, and composite material development have a need for such high-performance engineering ceramics.
Alumina Ceramic – Al2O3
Alumina ceramic is one of the most widely used ceramics in many areas such as semiconductor process equipment parts, seals, electronic substrates, industrial machinery components and automotive sensors.
