quartz glass
Noun: * A type of colorless, highly transparent glass: Quartz glass is a synthetic material composed almost entirely of silicon dioxide (silica). It is known for its exceptional purity, high resistance to heat and chemicals, and excellent transparency to ultraviolet light.
Quartz glass is a technical term used primarily in scientific, industrial, and specialized manufacturing contexts. * It is used to describe the material itself, not objects made from it (e.g., a "quartz glass crucible" or "quartz glass tube"). * Common in discussions about laboratory equipment, optical components, semiconductor manufacturing, and high-temperature applications.
- The laboratory furnace uses a quartz glass tube to contain the samples at extreme temperatures.
- Due to its purity, quartz glass is ideal for lenses in UV lighting systems.
- The optical fiber is made from a core of ultra-pure quartz glass.
- "Fused quartz glass": A specific type of quartz glass made by melting high-purity silica crystals. This term emphasizes the manufacturing process.
- The mirror for the telescope was crafted from a single piece of fused quartz glass.
- Fused quartz (n): Often used synonymously with "quartz glass," referring to the material created by fusing (melting) silica.
- Silica glass (n): A more general technical term for glass made from silicon dioxide, which includes quartz glass.
- Vitreous silica (n): Another technical synonym for quartz glass, highlighting its glassy (vitreous) state.
- Fused silica
- Fused quartz
The term specifically denotes the synthetic, amorphous (non-crystalline) form of silica glass. It is distinct from natural crystalline quartz, although both have the same chemical composition (SiO₂). The defining characteristic is its glassy state and high purity.
- colorless glass made of almost pure silica
