Titanium disulfide is yellow crystalline powder with metallic lustre. It is stable at room temperature, further stable to water, dilute sulfuric acid and hydrochloric acid. However nitric acid and sulfuric acid can resolve it and separate out sulfur. It has layers structure and every layer include S-Ti-S interlayer, between the interlayer contact by weak van der waals force. Titanium wire and sulfur or titanium tetrachloride and hydrogen sulfide are the raw material.
Titanium sulfide is a layered transition metal dichalocogenide known for its excellent electrical conductivity, thermal stability, and unique layered structure. These properties make TiS2 highly valuable in advanced applications, particularly in energy storage, electronics, and catalysis. As industries seek innovative materials to improve efficiency and performance, titanium sulfide’s versatility and stability offer distinct advantages.
