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.
