Production Processes

Electric fusion is the most commonly used melting process for manufacturing quartz glass. Two methods of electric fusion can be used: continuous and batch (boule) fusion.

Was originally known as the Verneuil process.

If highest purity is required our synthetic fused silica is the material of choice. Produced by the flame hydrolysis from the gaseous phase of highest purity silicon precursors we have improved the purity by several orders of magnitude.

OM 100 is produced in an innovative process developed and patented by Heraeus Quarzglas. The resulting material properties are much superior to those of other opaque products.
