Ca2O
ceramic· JVASP-114727· Ca2O
Calcium oxide (Ca₂O), also known as quicklime or burnt lime, is an alkaline ceramic compound produced by thermal decomposition of limestone and widely used in construction, chemical processing, and metallurgy. This material is valued for its reactivity with water and CO₂, making it essential in cement production, steel refining, and environmental remediation applications where its high alkalinity and ability to absorb moisture are leveraged. Engineers select calcium oxide for processes requiring strong base chemistry and thermal stability, though its hygroscopic nature and caustic properties require careful handling in design specifications.

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.
