As industries move toward high-performance, eco-friendly materials, the demand for bismuth-based compounds is gaining strong momentum worldwide.

The Bismuth Iodide Market was valued at USD 300 million in 2024 and is projected to expand from USD 300 million in 2025 to approximately USD 500 million by 2035. This growth reflects a compound annual growth rate (CAGR) of about 5.9% over the forecast period (2025–2035).

Understanding Bismuth Iodide and Its Properties

Bismuth iodide is an inorganic compound formed by the reaction between bismuth and iodine. It appears as a dark red to black crystalline solid with excellent optical transparency and semiconducting behavior. BiI₃ is particularly valued for its high atomic number and density, which make it effective in detecting X-rays and gamma rays. Additionally, it has a relatively wide band gap and strong photoelectric response, making it suitable for next-generation optoelectronic applications.

Its non-toxic nature compared to lead-based materials is a key factor boosting its adoption. Environmental and health concerns over heavy metals have encouraged researchers and manufacturers to develop bismuth-based materials as sustainable alternatives in various applications, especially in the electronics and medical sectors.
