· Ca4 Ti4 Ge4 O20

Ca₄Ti₄Ge₄O₂₀ is a mixed-metal oxide ceramic compound combining calcium, titanium, and germanium—a quaternary oxide that belongs to the family of complex perovskite-related structures. This is primarily a research material rather than a commercial product, studied for its potential electronic and photonic properties arising from the combination of Ti⁴⁺ and Ge⁴⁺ cations in an ordered oxide framework. Interest in such compounds centers on their potential as wide-bandgap semiconductors or functional ceramics for photocatalysis, optoelectronics, or solid-state device applications where the mixed-valence metal coordination offers tunable electronic properties.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
