Get Price· There are two methods for producing fused quartz: electric fusion and flame fusion. The electric fusion is the most commonly used melting process for manufacturing fused quartz glass. We use fused quartz as it has a very low OH (hydroxl) content which helps retard devitrifiion. One example of fused quartz is GE 124.
Get Price· Fused silica is produced by melting highpurity silica and then rapidly cooling it. It has good physical and chemical properties, which also make it the raw material for most components in the optical industry, and is widely used in optical fiber communiions, semiconductors, and aerospace.
Get PriceThe present invention has for its object the fusion of silica and, in particular, the production of improved vitreous silica resulting from the fusion of crystalline silica. When crystalline silica or quartz is heated .to temperatures approximating fusion, it first disintegrates into many fragments.

Get PriceWe work with a fused silica optical window, optical glasses, and crystalline substrate materials such as CaF2 and MgF2. All this while producing laser line windows in a wide range of sizes and geometric shapes. We utilize a variety of coating techniques .
Get Price· The terms "fused silica" and "fused quartz" are often used interchangeably. More accurately, "fused quartz" refers to an amorphous solid formed by melting naturallyoccurring quartz. So, while fused silica is ostensibly pure SiO 2, fused quartz contains impurities depending on the quartz that was used.
