Fused silica is a high-purity, non-crystalline material manufactured through oxidation of raw silica in a flame hydrolysis process, while fused quartz is fabricated by the melting of naturally occurring quartz. Each process yields specific characteristics optimized for use within a given range of the UV, Visible and Near-Infrared portions of
UV Fused Silica Windows feature low distortion, excellent parallelism, low bulk scattering and fine surface quality. This makes them perfectly suited for a wide variety of demanding applications, including multiphoton imaging systems and intracavity laser applications. Extremely low bulk scatter and autofluorescence
Fused silica is silica heated up to a liquid phase and cooled down without allowing it to crystallize. Pyrogenic or fumed silica is silica prepared by the combustion of a volatile silicon compound (usually SiCl(4)). Precipitated silica is silica precipitated from an aqueous solution. Colloidal silica is a stable dispersion of discrete, colloid
In the following passages, I would like to analyze the process flow of silica sol castings and the time required for each process in general. Silica sol castings mainly have four major processes: wax making, shell making, casting, and post-processing. After these four major processes are completed, the casting blank can be produced to meet the
