Bi4 B4 O14

Bi₄B₄O₁₄ is a bismuth borate ceramic compound belonging to the family of complex metal borates, which combines bismuth oxide with boric oxide in a defined stoichiometric ratio. This material is primarily investigated in research contexts for optical, photonic, and electronic applications, leveraging bismuth's high refractive index and heavy-element properties to create ceramics with potential for nonlinear optical behavior, radiation shielding, or specialized dielectric performance. Bismuth borates are of growing interest as alternatives to lead-based compounds in functional ceramics, particularly where heavy-element transparency or radiation interaction is desirable without the toxicity concerns of traditional lead borates.
