  • Fusion Technologies and Benefits

    In the following you will find an overview of the different fusion technologies that Heraeus Conamic can utilize, each highlighted by the leading material advantage in this segment.

    Natural Fused Quartz

    Electrically Fused Quartz Rods

    HSQ®100 single-step quartz rods are drawn in an electrical fusion process resulting in a cost-efficient solution for many industrial applications.

    For more demanding and high-end semiconductor applications Heraeus Conamic can provide multi-step and improved single step electrically fused quartz rods in HSQ®300, HSQ®330 and HSQ®330S material quality depending on the purity requirements of the customers’ application.

    This results in a material with enhanced homogeneity and low OH-content for high thermal stability in the final application.


    Synthetic Fused Silica
