  Heraeus Conamic | Making of fused quartz and fused silica

  Fused Silica In this process, the silicon containing precursors (e.g. Silicon Tetra Chloride; STC) burn in the presence of oxygen to form nano-particles of silicon dioxide, also called soot. Precise production and refinement of precursors leads to exceptionally high purity and the resulting fused silica has a very low metallic impurity content.

  Ductile and Brittle Mode Grinding of Fused Silica

  201096 · A creep feed taper grinding method was applied to investigate the relationship between maximum grit depth of cut and surface integrity of fused silica. Ductile mode grinding was achieved on fused silica. When the depth of cut exceeds the critical wheel depth of cut, the surface suddenly changes from the ductile mode to the brittle mode.
