· K4 Na2 B2 P4

K4Na2B2P4 is an experimental mixed-cation borophosphate compound belonging to the family of phosphate-based semiconductors, combining potassium, sodium, boron, and phosphorus elements in a framework structure. This material is primarily of research interest for optoelectronic and photonic applications, particularly in nonlinear optical devices and solid-state ion-conducting systems, where its mixed-alkali composition may offer advantages in tuning bandgap, thermal stability, and ionic transport properties compared to single-cation borophosphates.
