Industry-Leading High-Purity Quartz Sand Technology

Using its independently developed high-purity quartz sand production technology, ESSN has pioneered full-process R&D tracking, achieving an R&D conversion rate of nearly 90%. Compared with traditional production methods, ESSN's purification technology offers advantages such as lower energy consumption and lower cost. The high-purity quartz sand it produces has excellent flowability, better meeting the needs of downstream continuous-melting-tube and crucible customers.

ESSN has developed innovative high-purity quartz sand production technologies tailored to different ore sources. These technologies make more efficient use of the advantages of natural quartz, giving full play to its high temperature resistance and excellent electrical conductivity.

• 

  High Metal Ion Technology

  The "high metal ion" technology greatly improves the high-temperature resistance and devitrification resistance of high-purity quartz sand, significantly enhancing stability in applications and meeting the performance requirements for ultra-long-life quartz materials.

• 

  Low Alkali, Low Titanium

  Through R&D, alkali ions and titanium ions are controlled within a specific range, reducing the impact of total impurities on quartz material performance and greatly improving stability.

• 

  Low Diffusivity

  Through continuous R&D and experimentation, ESSN has established optimized purification standards for different metal and non-metal ions, minimizing electronic product quality issues caused by elemental impurity diffusion.
