Mohs'' Hardness (Typical) of Abrasives table from READE. Abrasive blasting for surface preparation is an important step in providing a foundation for protective coatings. For years, tests have concluded that highperformance coatings provide excellent corrosion protection and durability when applied over a blastcleaned surface with a consistent anchor profile.
Crystal quartz is a very useful material for fabrication of finished optics: laser beamsplitters, AO elements, polarizing optics, prisms, windows, lenses in the ultraviolet because of its high UV, VIS and NIR transmittance. Fused Silica is used for viewing windows, being transparent to wavelengths from around to µm.
Hardness. The hardness of Fine Ceramics is generally indicated using a Vickers hardness number. The method for measuring the hardness of Fine Ceramics is defined in JIS R 1610 (ISO 14705: 2000). Vickers hardness is a resistance value obtained by pressing a diamond indenter onto a test specimen.

Silica sand from Kandal province, Cambodia and Tap Perak, Malaysia was grounded into an average micron size of and µm. Both sands were characterized by Xray fluorescence (XRF), Xray Diffraction, particle Size Analysis, Differential Thermal Analysis and Thermogravimetric Analysis (DTA/TGA). Malaysian silica sand was designated SDMTP and Cambodian Silica sand as SDCK.
The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.

Silica sand products are marketed in a wide range of grades, including extremely fine grades known as flours. The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with a chemical formula of SiO2 and has been known for its hardness since antiquity.
Sand Wikipedia. The most common constituent of sand, in inland continental settings and nontropical coastal settings, is silica (silicon dioxide, or SiO 2), usually in the form of quartz, which, because of its chemical inertness and considerable hardness, is the most common mineral resistant to weathering.
In contrast, quartz has a Vickers hardness of approximately 1,200 (7 on the Mohs scale), which is roughly times harder than chrome steel. Quartz was chosen for comparison because it is one of the most abundant minerals in soil (primarily sand). Silicadioxide crystals are commonly referred to as quartz and can be found in most soils.
