High-purity metallic arsenic of which we have a large share in the global market is used to make gallium arsenide semiconductors, and is also used as dopants of n-type Si. In addition, compounds of high-purity metallic arsenic and Calcogen (S, Se etc) are used as trans-IR devices and glassy semiconductors.
High-Purity Metallic Arsenic
High-purity metallic arsenic is used to make gallium arsenide semiconductors. We succeeded in its mass-production and supply most of the domestic demand.
High-Purity Compounds
We make to order various types of high-purity compounds such as Arsenide or Calcogenide compounds.
GaP Polycrystals
Gallium phosphide is used to make light-emitting diodes.
