Single crystal （Sapphire・Magnesia・Crystalline material）

Crystal is solid material which has cyclic atom arrangement spatially and its structure is interspace cancelli. Rock crystal is typical crystal and has specific crystal face and axis. It has unique symmetric property and regularity between face angle and plane direction.

The following are some of our handling crystalline materials.

Sapphire single crystal （Ａｌ₂Ｏ₃）

Sapphire single crystal is applied in wide varieties of fields such as electronic parts optical parts using its' excellent mechanical feature, chemical stability, optical feature.

Examples of products Substrate GaN、Wafer Parts of semiconductor manufacturing system Carrie Wafer、Carrie arm Optical parts Window Others Deposition material, Polishing material, Analytical cell

Magnesia single crystal （MgO）

Magnesia single crystal is used in the field of cutting-edge technology such as electron beam evaporation material and coating substrate using its excellent spada resistance, electrical insulation, heat conductor and optical features.

Examples of products Substrate Wafer Electrode overcoat material for PDP Others Optical material, High-temperature material

Synthetic Optical crystal

NaCl（Natrium Chloride）
It is clear cubic crystal and one of the most popular infrared transparency material with rock salt structure. It is used in window, lens and prism material in infrared region (up to 16μ.)


KCl（Potassium chloride）
It is clear cubic crystal with rock salt structure and used in window and lens material in infrared region (up to 20μ). It is also used in infrared spectrometer cell and measuring salt bridge of electric conductivity.


KBr（Potassium Bromide）
It is clear cubic crystal with rock salt structure and used in window and lens material in infrared region (up to 27μ).
It is also used in powder of infrared absorption spectral measure.


LiF（Lithium Fluoride）
It is clear cubic crystal with rock salt structure. It has great optical transparency in 0.11μ of vacuum UV and 7μ of infrared region and is used in infrared prism and analysing crystal of vacuum UV.


MgF₂（Magnesium Fluoride）
It is clear cubic crystal with rutin structure. It has great optical transparency in 0.11μ of vacuum UV and 7.5μ of infrared UV and is used in window and prism materials.　Especially it is ideal for window material for excimer laser and it is also used for deposition materials.
