General Description 1: A yellow or gray powder that has an unpleasant odor. It is used as a solid lubricant. TiS2 is very toxic for humans. If it comes in contact with water, hydrogen sulfide is produces, which is a toxic flammable gas. Inhaling the gas can cause severe injury or death.
Fire Hazard. TiS2 is moisture sensitive and is very flammable when it comes into contact with moisture or air.
Thin films of TiS2 are used in Lithium Ion Batteries 2
Belongs to the transition metal dichalcogenides 3
TiS2 nanotubes can be used as a hydrogen storage material 3
Lattice Parameters 4:
a = 3.40 Å
c = 5.69 Å
c/a = 1.67
hexagonal, space group P3m1,
Basic Parameters at 300 K:
