WebAug 4, 2024 · There is often interchangeable use of the terms “fused quartz” and “fused silica”. However, “fused quartz” more specifically refers to an amorphous solid formed by melting naturally occurring quartz. This means that while fused silica is ostensibly pure SiO 2, fused quartz contains impurities dependent on what quartz was used. WebFused Silica is the glassy form of Quartz and is thus isotropic. Fused Silica is tough and hard and has a very low expansion. Normal varieties of Fused Silica contain water which gives strong absortion in the IR. Water-free …
WebJul 29, 2024 · THE COEFFICIENT OF LINEAR thermal expansion (CTE, a, or a1) is a material property that is indicative of the extent to which a material expands upon heating. Different substances expand by different amounts. Over small temperature ranges, the thermal expansion of uniform linear objects is proportional to temperature change.
