· JVASP-98330· Ca4Al2H22CO20

Ca4Al2H22CO20 is a calcium aluminate hydrate ceramic compound, likely a calcium aluminate cement (CAC) hydration product or related calcium-aluminum-carbonate composite. This material belongs to the family of cementitious ceramics and appears to be a research or specialized compound rather than a commercial product with established industrial applications. The presence of carbonate and high water content suggests potential use in low-temperature ceramic bonding, refractory applications, or as an intermediate phase in cement chemistry—areas where engineers would value its bonding capacity and thermal stability over conventional materials.

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.
