· Ca4 C4 O12

Ca₄C₄O₁₂ is a calcium carbonate-based ceramic compound that belongs to the family of oxycarbonates, combining calcium, carbon, and oxygen in a structured crystalline form. This material is primarily of research and developmental interest in advanced ceramics, with potential applications in refractory systems, cement chemistry, and high-temperature structural applications where its calcium-carbonate backbone offers thermal and chemical stability. Notable in the cement and materials chemistry field as a phase that can appear in calcium-rich ceramic systems, it is studied as an alternative or supplementary phase to conventional Portland cement constituents, particularly where enhanced durability or specialized thermal properties are desired over standard cement formulations.

Regulatory Screening

Environmental

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.
