SrO
ceramic· SrO
Strontium oxide (SrO) is an alkaline earth ceramic compound commonly used as a raw material and additive in high-temperature and electrochemical applications. Its primary industrial use is in cathode materials for solid oxide fuel cells (SOFCs), where it enhances ionic conductivity and thermal stability, and as a component in refractories, glass formulations, and specialized ceramics that must withstand extreme temperatures. Engineers select SrO-based materials when high-temperature chemical stability, ionic conductivity, or low thermal expansion are critical, making it particularly valuable in energy conversion devices and harsh thermal environments where conventional ceramics fall short.

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.
