Fused quartz is well known for its high purity and excellent thermal and optical properties, and plays an important role in many advanced technologies. This article will explain the knowledge points of fused quartz, explain its evolution, characteristics and impact on future technologies, and help customers better understand our fused quartz.
Elements of fused quartz
Fused quartz originated in the early 20th century and played an important role in the production of laboratory glassware, and later played a large role in World War II, electronics and aerospace projects. Among them, fused quartz is made by melting natural quartz crystals. Compared with synthetic products, it has higher UV transmittance, but lower optical quality.
Its melting point exceeds 1700℃, its low thermal expansion rate and excellent optical clarity make it an ideal choice for aerospace, photonics and precision instruments. Among them, we will also specifically introduce the characteristics of fused quartz’s high melting point and applicable industries below.
The production of fused quartz involves melting high-purity silicon dioxide at temperatures above 2000 degrees Celsius, and recent advances have improved its purity and environmental sustainability.
Fused quartz is essential in aerospace (for windows and mirrors), nanotechnology (due to its purity and stability) and renewable energy, especially in solar panels where it can absorb light efficiently.
What is fused quartz?
Quartz itself is a crystalline mineral composed of oxygen and silicon and is one of the most abundant naturally occurring minerals on Earth.
Fused quartz is made by melting natural quartz crystals. Natural quartz crystals tend to contain more impurities than synthetic alternatives, which means it produces glass of lower optical quality and more defects and bubbles.
Nonetheless, these defects are invisible to the naked eye and only prevent the glass from being used for imaging applications and optically demanding applications. Fused quartz still has a higher UV transmittance than most other glasses. For achieving high transmittance in the UV, where fused quartz cannot transmit or transmits only slightly, fused quartz would be the material of choice.
In-depth analysis of fused quartz properties
Fused quartz’s high melting point of over 1700°C enables it to withstand extreme temperatures, a key attribute in industries such as aerospace and metallurgy. Its low coefficient of thermal expansion ensures minimal dimensional changes under temperature fluctuations, making it ideal for precision instruments such as telescopes and high-tech manufacturing equipment. These unique properties, combined with its resistance to chemical attack and minimal risk of contamination, set fused quartz apart from other materials, including fused silica, which, although similar, have different applications and properties.
The Art of Fused Quartz Manufacturing
The manufacturing of fused quartz is a complex process that depends on melting high-purity silica in specialized furnaces at temperatures exceeding 2000°C. This extreme high temperature is necessary to ensure that the raw silica is converted into a uniform, amorphous state. Recent technological advances have improved this process, allowing for the production of fused quartz of even higher purity. The continued development of manufacturing techniques highlights the industry’s commitment to meeting the stringent standards of advanced technology while being mindful of environmental impact.
Applications of Fused Quartz in Modern Industry
The applications of fused quartz in modern industry are varied and vital. In the aerospace industry, its use in windows and mirrors is invaluable due to its exceptional durability and resistance to extreme temperatures, ensuring safety and functionality in harsh environments. In the field of nanotechnology, the high purity and thermal stability of fused quartz are essential for precise and reliable experimentation and manufacturing.
Additionally, in the renewable energy sector, fused quartz plays a key role in solar panels. Its superior optical properties enable more efficient light absorption, thus increasing the overall efficiency of solar energy systems. These examples underscore the adaptability of fused quartz to a variety of modern industrial needs, highlighting its importance in advancing technology and sustainability.
