· RbPS3

RbPS3 is a layered ceramic compound composed of rubidium, phosphorus, and sulfur, belonging to the family of metal phosphorus trisulfides. This material is primarily investigated in research contexts for its potential in energy storage and optoelectronic applications, rather than as an established commercial engineering material. The layered structure characteristic of this compound class makes it of interest for applications requiring ionic conductivity or two-dimensional material properties, though industrial adoption remains limited compared to conventional ceramics.
