Quartz glass definition
Quartz glass is a unique type of glass composed almost entirely of silica (SiOâ‚‚). Unlike regular glass, which often contains various impurities and additives, quartz glass is made from highly purified silica, giving it exceptional properties. Due to the variety in production methods, raw materials, and applications, different countries have used various names for this material, such as silicate glass, fused silica, fused quartz, synthetic fused silica, and even transparent, translucent, or opaque quartz. However, these terms are not always clearly defined. In China, the general term used is "quartz glass," and it is further categorized based on the manufacturing process, application, and appearance. For example, there are fused transparent quartz glass, gas-refined transparent quartz glass, synthetic quartz glass, optical quartz glass, semiconductor-grade quartz glass, and quartz glass used in electric light sources.
It’s important to note that using the term “quartz†alone to describe this material can be misleading. The word “quartz†refers specifically to the crystalline form of silica, whereas quartz glass is an amorphous (non-crystalline) form. This distinction is crucial because the physical and chemical properties of crystalline quartz differ significantly from those of glassy silica. Using the wrong term could lead to confusion about the material’s performance, especially in technical or industrial applications where precision matters.
In summary, while quartz glass may seem similar to regular glass at first glance, its composition and properties make it a specialized material with a wide range of high-performance uses in optics, electronics, and scientific research. Understanding the correct terminology helps ensure accurate communication and proper application of this advanced material.
