  • N-9000NS Translucent Alumina Ceramics
    Translucent Alumina ceramic which has high total light transmittance and high mechanical strength like single crystal sapphire. -Cost competitive than a Sapphire (In case complex shape/bar shape) -High intensity -Super hard material...

  • Nishimura’s original translucent alumina ceramics is composited of very small ceramic crystal (0.2-2μm Ave.0.9μm).
    As a unique point of this material(difference from a sapphire) is that it can be shaped in a variety of shapes.
    This material is fit to the standards of the medical used high purity alumina ceramics.(ISO6474, ASTM F603)
    As a below picture, the ceramic crystal is a small hexagon. Therefore the crystals berry drop is not usually happen

    Unique Point

    -Cost competitive than a Sapphire (In the case of complex shape/bar shape). It can be produced by a green-machining method to saving the cutting cost.
    -High intensity
    -Super hard material
    -High purity Alumina 99.99%


    • Parts for semiconductor devices
    • Alternative material of Sapphire
    • Substrates for electric parts
    • Heat-resistant and Corrosion-resistant material. E.g. Reaction tube, crucible
    • Medical equipment and analyzers
    • RF Window
  • VM-6 Partial vacuum Chuck

  • VM-6 is the innovative vacuum chuck with micro porous ceramics(1μm pores).
    It can adsorb and fix many smaller objects 

    Adsorbed objects exapmle
    It can be applied for adsorbing small objects with smooth surface
    -small plates, films, circuit boards, and so on.

    We develop and produce it based on customer requests, such as the chuck reform the film warp, prevent ESD, having black color, and so on.

    We can produce a large-size vacuum chuck(over □2m) also.

    Please try our partial adsorbing vacuum chuck VM-6 with the free rental test kit!
