· Sr2 Bi4 B8 O20

Sr₂Bi₄B₈O₂₀ is an inorganic ceramic compound belonging to the bismuth borate family, combining strontium, bismuth, boron, and oxygen in a layered crystal structure. This is a research-phase material investigated primarily for photocatalytic and optical applications, where bismuth-containing oxides are valued for their narrow bandgaps and visible-light responsiveness. The material represents an emerging class of functional ceramics with potential in environmental remediation and energy conversion, though it remains largely in academic study rather than established industrial production.
