KTlCl4

ceramic

· KTlCl4

KTlCl₄ is an inorganic halide ceramic compound containing potassium, thallium, and chlorine, belonging to the family of complex metal halides. This material is primarily of research and specialized optoelectronic interest rather than a mainstream engineering material, with applications in scintillation detection and potentially in nonlinear optical systems where its crystal structure and halide composition offer unique photonic properties.
