· Ca1 O2

Calcium oxide (CaO), commonly known as quicklime, is an inorganic ceramic compound and semiconductor material with a simple rock-salt crystal structure. It serves as a fundamental industrial chemical with widespread use in construction, metallurgy, and chemical processing, where it functions as a high-temperature refractory material, lime binder, and flux in steelmaking. Engineers select CaO for applications requiring high-temperature stability, strong reactivity with acidic oxides, and cost-effectiveness, though its hygroscopic nature and tendency to slake (react with moisture) necessitate careful handling in sensitive applications.

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.
