Fused Quartz / Fused Silica Hard Machining .Översätt den här sidan

Fused silica grades termed UV grade are better controlled from these metals, and so they transmit further into UV ranges. But their drawback is OH caused absorption, especially at 2.2um and 2.7um. All SiO2 glasses share some properties, including extreme hardness, very low thermal conductivity, low thermal expansion, and a wide range of optical transmission from UV to IR.

Thermal Properties of Silica Gels | SpringerLink

Silica aerogels are very exceptional materials in the huge panoply of solids: densities as low as 0.1 times that of amorphous silica can be obtained. In such systems, the distribution of matter is highly inhomogeneous, and this fact raises the problem of the nature of low-energy excitations (phonons, fractons, two-level systems) and their contributions to the low temperature properties.

Silica Health Benefits, Uses & Side Effects in Humans

Silica can act as a detox machine of toxins and heavy metals in the body. One such example is aluminium and alumunium toxicity. Its ability to bond aluminium prevents the absorption of this metal in the gut. This prevents the occurrence of toxicity and sequelae.

Silica gel - Wikipedia

Properties. Silica gel's high specific surface area (around 800 m 2 /g) allows it to adsorb water readily, making it useful as a desiccant (drying agent). Silica gel is often described as "absorbing" moisture, which may be appropriate when the gel's microscopic structure is ignored, as in silica .

All About Silicon Bronze (Properties, Strength, and Uses)

The tensile yield strength of silicon bronze comes in a wide range, but the higher silicon bronze alloys are impressively strong (~400 MPa). The tensile yield strength is a measure of how much stress (or force per unit area) that a specimen of metal can endure without plastically (permanently) deforming in tension.
