Our Business

Products

High-purity materials

Key technologies that support the evolution of communication equipment

We are Japan’s only manufacturer of the high-purity metallic arsenic used to manufacture gallium arsenide semiconductors, and boast the global top share of the material.

Cores and coils

Dust cores and coils that contribute to greater stability and efficiency in power supplies and circuits

Leveraging our technology for in-house production of cores, we are able to offer detailed solutions and prototyping that meets customers’ needs.

Aluminium nitride (AIN) ceramics

Outstanding thermal conductivity and electrical insulating properties

Applications for aluminum nitride ceramics are expanding to semiconductor manufacturing equipment components, substrates, and fillers. We are able to provide products ranging from filler a few microns in size to large sintered parts.

Optical elements and units

We connect light to contemporary living with infrared-region optical components

We provide optical components for laser cutting machines, infrared thermometers, and night-vision cameras, as well as polishing and coating of other crystals.
