Physical Properties of Calcite & Quartz | Sciencing

Calcite is a polymorph of calcium carbonate, meaning that it is one of many crystalline forms of calcium carbonate (argonite would be another), whereas quartz is a polymorph of silicon dioxide.Both mineral crystal structures fall under the trigonal-crystal-shape category, though calcite differs slightly in that it exhibits a rhombohedral lattice structure.

Rose quartz: The pink gemstone rose quartz information and ...

Rose Quartz is a very affordable gemstone. Due to its often hazy color and frequent flaws, it is more often tumbled or used as beads over faceting into gemstone cuts. A deeper pink color in Rose Quartz makes it less common and more desirable, though certain forms of Rose Quartz may fade upon repeated prolonged exposure to strong lighting.

Crystal quartz (SiO2) and Fused Silica - mt-berlin

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 0.2 to 3.5 µm.

Momentive -Mechanical Properties of Fused Quartz

Mechanical properties of fused quartz are much the same as those of other glasses. The material is extremely strong in compression, with design compressive strength of better than 1.1 x 10 9 Pa (160,000 psi). Surface flaws can drastically reduce the inherent strength of any glass, so tensile properties are greatly influenced by these defects.
