transparent quartz
Học thuậtThân thiện
Definition
Noun: - A clear, colorless variety of quartz, which is a hard, crystalline mineral. It is valued for its transparency and is used in the manufacture of electronic and optical devices.
Usage
The term "transparent quartz" is used to specify the pure, clear form of the mineral quartz (silicon dioxide, SiO₂). It distinguishes this variety from colored or opaque forms like amethyst (purple) or smoky quartz (brown/gray). Its primary use is in technical and industrial contexts.
Examples
- The lenses were made from high-quality transparent quartz.
- Transparent quartz is an essential material in the semiconductor industry.
- This specimen of transparent quartz is remarkably clear and free of inclusions.
Advanced Usage
- In geology and mineralogy, "transparent quartz" is often referred to simply as "rock crystal."
- In manufacturing, it may be specified as "fused quartz" or "quartz glass" when it has been melted and formed into a non-crystalline (amorphous) solid for specialized applications.
Variants and Related Words
- Rock crystal: The common name for transparent quartz in its natural, crystalline form.
- Fused quartz / Quartz glass: A synthetic material made by melting pure transparent quartz, used for its high purity and thermal stability.
- Silica: The chemical compound (SiO₂) that is the main component of quartz.
Synonyms
- Rock crystal
- Clear quartz
- Colorless quartz
Notes on Meaning
While "transparent quartz" directly refers to the clear mineral, it is important to distinguish it from the broader term "quartz," which encompasses many varieties. Its defining characteristic is its optical clarity, which allows light to pass through with minimal distortion.
Noun
- a clear quartz used in making electronic and optical equipment
