    Alsima L is a high-purity heat insulating ceramic originally developed by ASUZAC. Alsima L is a ceramic that is more resistant to thermal shock, lower in thermal expansion and thermal conductivity than ordinary alumina ceramics.
    In addition, because it is dense, it generates little dust and can be used as a heat insulating material in places where particles should be eliminated. Also it can be used as a component for preventing heat diffusion around the heat source.

    The bulk density is 60% that of alumina, so it is lightweight. Thermal conductivity is 1/10 that of alumina, so it can serve as a heat insulator.
    The coefficient of thermal expansion is about one-third that of alumina, and it can withstand rapid change in temperatures from heating-up and cooling-down.

    * Alsima L is ASUZAC's original product name.

  • Features

    • Alsima L has a high heat-resistant temperature (900℃)

    • Alsima L has a low coefficient of thermal expansion (2.1x10-6 1 / K).

    • Alsima L has low thermal conductivity (2.9W / (m · K)

    • Alsima L has low specific (2.4g / m3)

    • Alsima L has thermal shock resistance

    • Alsima L has low particle generation (suppresses dust generation like refractory bricks)

    • Alsima L has good detachability and removability.

  • Applications

    • Insulation around the heating element

    • Places (tables / stages) that require low thermal expansion

    • A glass-melting crucible or a firing jig, using its good removability from glass

    • Places where particle prevention is required

    • Places where other ceramics could not be used due to the lack of thermal shock strength.
