Quartz Tube and Rod Information
Quartz tube and rod consists of hollow and solid stock configurations of fused quartz materials. They function in an array of applications, including laboratories, semiconductors, sight gages, optics, pharmaceutical and industrial processes. Quartz is shock resistant, allowing it to withstand harsh environments. It possesses unique properties enabling its use in fields such as IC fabrication, lasers, and water treatment via UV lamps. Quartz is also found in many watches.
Fused quartz is comprised of silica, a typical substance making up almost one-third of the earth’s crust. Vitreous silica is the generic name for silica glass while manufacturers refer to the element as fused quartz or fused silica. Melting of a naturally occurring substance, known as crystalline silica, facilitates the production of the vitreous silica. This includes sand and rock crystal. The material is fused either by electrical means (electrically fused) or by gas/oxygen (flame fused). The finished products appear transparent, opaque, or translucent, allowing for the formation of a broad selection of items. Fused silica, also known as synthetic fused quartz, is made from silica sand of exceptional purity and possesses a translucent appearance.
Fused quartz has special properties that make it valuable to the production of modern instruments and other equipment. These attributes include:

Glass and quartz function as crystals employed in both decorative and industrial activities. While glass is featured in prisms, windows, pendants, and other jewelry, quartz is found in watches and industrial products such as electronic devices.
The key differentiating factors between glass and quartz are as follows:
- Quartz features a high content of silicone dioxide (at least 99 percent). Glass crystal, however, has a maximum of up to 80 percent of the substance. Moreover, glass products consist have lead levels of 32% to enhance the refractive index and improve quality.
- When cut, glass crystal presents a random molecular form, whereas quartz displays a symmetrical structure. Due to the irregular structure of glass, it is considered an amorphous solid. Quartz, along with other semi-precious crystals such as sapphire, ruby, and diamonds, attains a symmetrical form or an irregular one due to weathering or excessive pressure.
- Both glass and quartz are found in the crust of the earth. However, quartz crystal by nature withstands heightened temperature and pressure levels. As a result, it is best suited for conditions where a protective covering is required. The crystal substitutes glass in harsh settings.
- Reaction of the substances to electricity is another critical aspect. Glass works well as an insulator while quartz is an ideal conductor of electricity. As a result, many industrial products incorporate quartz due to its electric properties.
