High-Purity Quartz for TFT Substrates and Advanced Display Applications

As display technologies continue to evolve toward larger sizes, higher resolution, and thinner structures, the demand for high-purity raw materials has never been higher. Quartz, as a critical component in display glass production, plays a decisive role in determining optical performance, thermal stability, and overall yield.

Our high-purity quartz is specifically engineered for TFT substrate glass and various display applications, including LCD, OLED, Mini-LED, and other advanced flat panel displays.

Exceptional Chemical Purity for Display-Grade Glass
With a SiO₂ content of 99.9616% and an extremely low loss on ignition of only 0.00087%, this quartz ensures:

• Stable melting behavior
• Minimal gas release during fusion
• Reduced risks of bubbles, streaks, and inclusions

Such purity levels meet the stringent requirements of modern high-generation TFT glass production lines.

Ultra-Low Iron Content for Superior Optical Performance
Iron and titanium impurities are critical factors affecting light transmission and color consistency in display glass.
Our quartz features:
Fe: 49.66 μg/g
Ti: 19.20 μg/g
This low impurity profile helps achieve:

• High transparency
• Excellent color neutrality
• Improved display brightness and clarity

Controlled Alkali Content for Thermal and Chemical Stability
Carefully controlled levels of Na, K, Ca, and Mg contribute to:
• Enhanced thermal stability
• Better compatibility with downstream coating and circuit processes
• Reliable performance in high-temperature glass forming

Optimized Particle Size Distribution (120-600 Mesh)
• The quartz is available in a 120-600 mesh particle size range, offering:
• Uniform melting behavior
• Good flowability and low dust generation
• High adaptability to different glass melting technologies
This flexibility allows manufacturers to optimize their formulations without compromising quality.

A Reliable Choice for Advanced Display Manufacturing

Thanks to its high purity, low trace elements, and controlled particle size, this quartz is well suited for:

• TFT substrate glass

• Flat panel display glass

• High-end optical and electronic glass applications

It provides a stable and consistent raw material foundation for next-generation display technologies.
