Glass Fused Silica vs. Quartz Posted Krista Grayson on Jul 27, Quartz vs. Silica The first important thing to know about quartz and fused silica is that they both primarily consist of the same ingredient: silica , also known as silicon dioxide.

Crystalline and Amorphous Solids To fully understand the differences between different silica-based materials, we first need to review the fundamental differences between crystalline solids and amorphous solids.

Quartz As mentioned previously, quartz is the main form in which silica occurs in nature. Silica Glass and Quartz Glass These terms are typically used in a more generic sense, and can usually be considered interchangeable. Applications of Fused Silica While fused silica is chemically similar to quartz, its amorphous structure gives it a number of distinct and highly desirable thermal, mechanical and electrical properties. Custom Glass Solutions from Mo-Sci Mo-Sci develops and manufactures a range of high-performance glasses for technical applications.

Today, Fused Quartz is defined as a material made by melting high purity, naturally occurring quartz crystal.

Fused quartz is amorphous and non-crystalline. Residual impurities from the raw material affect Fused Quartz transparency in the ultraviolet.

Fused Silica also known as Synthetic Fused Silica is made from a silicon-rich chemical precursor, usually using a continuous flame hydrolysis process, which involves chemical gasification of silicon, oxidation of this gas to silicon dioxide, and thermal fusion of the resulting dust although there are alternative processes. Quartz also features a much lower OH content. It features very low thermal expansion and excellent optical qualities, including very high transmission in the UV spectrum.

GE is a very pure fused quartz, made from crystalline silica. GE is very similar to fused silica, with the exception of less transmission in the UV spectrum and much lower OH content.
