Quartz fiber

Quartz fiber is a fiber created from high purity natural quartz crystals.[1][2] It is made by first softening quartz rods (in an oxyhydrogen flame)[3] and then creating filaments from the rods.[4] Since natural quartz crystals of high purity are rare, quartz fiber is more expensive than alternatives (glass fiber and high silica fiber) and has limited applications.[3]

Manufacture

Quartz fiber is made from heating quartz rods with an oxyhydrogen flame. Then, filaments are drawn out of the quartz rod, creating quartz fibers.[5] For optical fibers, germanium and phosphorus can be added to increase the refractive index.[6][7]

Properties

A single quartz fiber can have a tensile strength of 800 kilopounds per square inch (5,500 MPa). Quartz fibers are chemically stable as they are not affected by halogens (for the most part). Quartz fibers also have a higher thermal resistance than S-glass or E-glass.[8]

Applications
A quartz fiber dosimeter, a device using a quartz fiber.

Since quartz fiber is expensive, it has limited applications.[2] It is used mainly for producing composite materials (due to having higher stability compared to glass fiber) and in electrical applications where thermal resistance and dielectric properties are important.[9] It can be used in filtration applications where alternatives such as glass fiber filters cannot be used.[3][10] Quartz fiber can also be used for physical devices (such as in quartz fiber dosimeters and quartz fiber electrometers).[11]

Quartz fibers can be used in fiber optics. This is due to a quartz fiber having the ability to transport data at a speed of 1 terabit per second,[12][13] and having a transmission loss of 1 decibel per kilometer.[14]
