Fields of application

Industry

Application Notes

Display glass (OLED/LED substrate)

As a glass melting flux and network-forming agent, it lowers melting temperatures while enhancing light transmittance, chemical stability and mechanical strength, making it a critical raw material for flexible OLED and ultra-high-definition LCD substrates.

Semiconductor manufacturing

Used for P-type doping and insulating layer preparation, providing a stable boron source in high-temperature processes.

Electronic paste

When combined with silver powder and copper powder, it forms a high-temperature sintered electrode paste, whose insulation and thermal stability ensure the reliability of conductive pathways.

High-end ceramic glazes

Enhance glaze lustre, hardness and wear resistance, while broadening the firing temperature range.
