CaBr2
ceramic· CaBr2
Calcium bromide (CaBr₂) is an inorganic salt ceramic compound commonly encountered in ionic crystal form, characterized by its hygroscopic nature and moderate mechanical stiffness. In industrial practice, CaBr₂ serves primarily as a dense brine fluid in oil and gas well completion operations, where it provides high-density drilling and completion fluids without the toxicity concerns of some alternatives. Beyond petroleum applications, it functions as a desiccant, refrigerant medium, and laboratory reagent, making it valuable in scenarios where non-toxic, water-soluble salt solutions are preferred over hazardous organics or other dense brines.

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.
