Precision Quartz Components

Precision Quartz Components

Ultra-precise small-scale quartz components for high-tech industries, designed with exceptional thermal and chemical stability for micron-level accuracy.

Advantages of quartz for high-tech manufacturing

Quartz and fused silica are renowned for their exceptional thermal stability,low thermal and electrical conductivity, optical transparency and high chemical purity. These materials also exhibit low coefficient of thermal expansion (0.55 to 0.57 x 10⁻⁶/°C) and can withstand temperatures exceeding 1,200°C without significant structural degradation. This makes quartz and fused silica the material of choice in applications like semiconductor manufacturing and advanced optics, where precision and durability are paramount.

Superior precision and stability

Both quartz and fused silica maintain their mechanical strength and dimensional stability at high temperatures, withstanding extreme heat fluctuations and thermal shock. With a melting point of 1,710°C for fused silica and 1,670°C for quartz, these materials are essential for industries like advanced photonics and semiconductor processing, where high operating temperatures and thermal cycling are common.

Quartz components, such as torches and reactor tubes, are engineered to resist rapid temperature changes and maintain mechanical integrity, ensuring consistent performance and longevity under extreme conditions.

Why choose quartz and fused silica for critical components?

Quartz and fused silica outperform metals, ceramics, and plastics in key areas that are critical for high-tech applications. Their superior thermal properties, including low thermal expansion and high thermal shock resistance, make them ideal for precision components that must maintain dimensional stability under extreme conditions. Their excellent dielectric strength (470 kV/cm for fused silica) also makes them indispensable in semiconductor and optoelectronics industries, where electrical insulation is critical.
