Bismuth oxide (Bi2O3)-based glass is a high-performance material with wide-ranging applications. Based on various studies and sources, the main applications include:

1. Optoelectronic Devices and Optical Fiber Transmission

Bismuth oxide-based glass has significant potential applications in optoelectronic devices and optical fiber transmission due to its high refractive index, infrared transmission, and nonlinear optical properties. In these materials, bismuth oxide is used as an additive in significant amounts. For example, the Bi2O3-B2O3-Si2O3 glass system exhibits ultrafast responses of less than 150fs, making it widely applicable in optical switching and broadband amplification. Additionally, bismuth-based glasses doped with cesium, such as 63.3Bi2O3-32.6B2O3-41Si2O3-0.24CeO2, demonstrate even better performance, with its content reaching as high as 63.3%, accounting for 92% of the glass by weight.

2. Low-Temperature Melting and Photonics Device Applications

Bismuth oxide-based glass exhibits high linear refractive index, low glass transition temperature, and high third-order nonlinear optical susceptibility, making it a promising material for low-temperature melting and photonics device applications.

3. Electronic Ceramic Powder Materials

Bismuth oxide serves as an important additive in electronic ceramic powder materials, primarily used in zinc oxide varistors, ceramic capacitors, ferrite magnetic materials, etc. In the development of electronic ceramics, the United States leads globally, while Japan dominates the world ceramic market with a 60% share through large-scale production and advanced technology.
In summary, bismuth oxide-based glass holds broad application prospects in fields such as optoelectronics, electronic ceramics, low-temperature melting, and photonics devices.
