Plasma Fusion Process QSIL
At the start of the process, high purity quartz sand is fed into a rotating furnace mold, with centrifugal force used to achieve dimensional control. During the fusion process, a high purity gas atmosphere is maintained in the mold while a plasma arc is sparked between the two electrodes. A t temperatures greater than 2000#176;C, t he energy of the plasma arc transforms the crystalline quartz
