· Ca4 Sn4 O10

Ca₄Sn₄O₁₀ is a mixed-metal oxide semiconductor compound combining calcium and tin in a defined stoichiometric ratio, belonging to the family of perovskite-related oxides. This material is primarily of research interest for optoelectronic and photocatalytic applications, where the combination of tin and calcium oxides can create tailored bandgaps and defect chemistry for light absorption and charge transport. While not yet widely deployed in mainstream commercial products, compounds in this family show promise as alternatives to lead-based semiconductors in next-generation solar cells, gas sensors, and photocatalysts for environmental remediation.
