In the electronic glass sector—including TFT-LCD substrate glass, cover glass, and semiconductor packaging glass—even trace impurities can cause critical defects in product performance. This demands near-demanding standards for the “high purity” and “low contamination” of refractory materials lining kilns.
Leveraging deep expertise in melting and casting materials, Zhengzhou Chaowei Refractories Co., Ltd. has successfully developed ultra-high-purity, low-leaching AZS and α-β alumina brick series specifically engineered for electronic glass furnaces. Through meticulous raw material selection and precise process control, these products minimize harmful impurities like Fe₂O₃ and SiO₂ to extremely low levels while significantly reducing glass phase leaching. This ensures “zero contamination” protection for highly sensitive electronic glass melts under prolonged high-temperature operation.
Our solutions have been successfully implemented across multiple domestic high-end electronic glass production lines, enabling clients to consistently produce premium products meeting stringent standards. From the melting and clarifying section to the forming channel, we provide optimal refractory configurations tailored for every critical component of electronic glass furnaces.
“Electronic glass represents the pinnacle of refractory applications,” notes the project manager. “Gaining client recognition in this field stands as the strongest testament to our technical capabilities and quality management system.”
Zhengzhou Chaoyu aspires to be the most reliable partner for global electronic glass manufacturers, safeguarding the exceptional quality of your products with our pure, stable refractory materials.
