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
Basic Parameters at 300 K:
Band structure and carrier concentration:
Carrier Concentration: 9 x1020 cm-34
A graph showing band structure for TiS2 can be seen at reference 3
A graph showing the temperature dependence of resistivity can be seen at reference 3
Room temperature conductivity 5: 7.6 x10-1 ohm-1 cm-1
A graph of electrical conductivity vs temperature can be seen at reference 4
Basic Parameters of Electrical Properties:
TiS2 is a Semimetallic 3
Mobility and Hall Effect 5:
A graph of Hall Mobility vs Temperature can be seen at reference 4
A graph of the measured reflectivity spectrum of TiS2 vs calculated spectra can be seen at reference 6
Absorption coefficient vs. phonon energy, etc.
