Fine Ceramics
We deal with silicon nitride (Si3N4) and aluminum nitride (AlN), materials possessing the highest standards in the world in terms of thermal conductivity and withstanding voltage, and with boron nitride (BN), having excellent insulation, heat resistance, and releasability. The highly advanced properties and features of our fine ceramics allow for a wide range of applications, such as in automobiles, semiconductors, and industrial machinery.
