Our Umbrella Brands

By defining umbrella brands, we would like to make it easier for our customers to find their way around our product portfolio.

Synthetic Fused Silica: 

Gaseous silicon containing chemicals are burned in the presence of oxygen to form silicon dioxide.

Natural Fused Quartz:

High purity quartz is fused using various heat sources.
