• Making of fused silica Heraeus

    For this process a plasma heat source is used to “burn” chemical precursors and deposit a thin glass layer on a rotating target. The target can be a tube or a solid rod, it is not necessarily round. Because of the high temperature of the plasma, this process is best suited to produce fluorine doped fused silica.
