Fused quartz, fused silica or quartz glass is a glass consisting of almost pure silica (silicon dioxide, SiO 2) in amorphous (non-crystalline) form.
Fused silica is a highly important material for a wide range of optical components, for dielectric coatings, and is also the most important base material for fiber optics. UV- and IR-grade fused silica are available for special applications.
Fused silica is an amorphous synthetic material which contains pure silicon dioxide (SiO 2). It has a melting point of 1858 K, and an abraded modulus of rapture of 52.4 MPa and a Poisson's ratio of 0.16 at 298 K ( Corning Incorporated, 2003 ).
Fused silica, also known as synthetic fused silica, is a type of glass that possesses superior optical properties and exceptional stability under extreme conditions. Primarily composed of silicon dioxide (SiO 2 ), this material is derived through the process of high-temperature fusion of high-quality silica sand.
4 de ago. de 2021 · The huge variety of names used to denote silica-based materials (quartz, fused silica, fused quartz and more) can make it deeply confusing to differentiate. This article from Mo-Sci goes on a deep dive into the unique properties of both materials.
Fused Silica: A Transparent Look at a Complex Material. The simplicity of fused silica’s base formula belies the range of its production methods, performance qualities, and grades.
Fused silica is an amorphous grade of silica known for its low thermal expansion and thermal shock resistance. It is made by melting high purity silica sands and has uses in refractories, investment casting, radar windows etc.
