· JVASP-35180· Sr4S3O

Sr₄S₃O is an oxysulfide ceramic compound combining strontium, sulfur, and oxygen, belonging to the family of mixed-anion ceramics that exhibit unique combinations of ionic and covalent bonding. This material is primarily investigated in research settings for its potential in solid-state electrolytes, optical applications, and refractory systems where the dual anionic network provides enhanced structural stability and thermal properties compared to conventional single-anion ceramics. Engineers consider oxysulfide ceramics like Sr₄S₃O when seeking materials with tailored electrochemical behavior, thermal resistance, or optical properties in advanced energy storage and high-temperature applications.
