· TiI3

Titanium triiodide (TiI₃) is a layered transition metal halide compound that exists primarily as a research material rather than an established commercial engineering material. It belongs to the family of metal halides and layered materials, making it of particular interest in materials science for its potential in two-dimensional electronics and energy storage applications. The material's layered structure and exfoliable nature position it as a candidate for emerging technologies, though industrial adoption remains limited and applications are largely experimental.
