Titanium trisulfide

Titanium disulfide can also be made by pyrolysis of titanium trisulfide at 550°C. A continuous process based on the reaction between titanium tetrachloride vapor and dry, oxygen-free hydrogen sulfide has been developed at pilot scale (173). The preheated reactants ate fed iato a tubular reactor at approximately 500°C. The product particles comprise orthogonally intersecting hexagonal plates or plate segments and have a relatively high surface area (>4 /g), quite different from the flat platelets produced from the reaction between titanium metal and sulfur vapor. The powder, reported to be stable to... 

Titanium trisulfide [12423-80-2], TiS, a black crystalline soHd having a monoclinic stmcture and a theoretical density of 3230 kg/m, can be prepared by reaction between titanium tetrachloride vapor and H2S at 480—540°C. The reaction product is then mixed with sulfur and heated to 600°C ia a sealed tube to remove residual chlorine. Sublimatioa may be used to separate the trisulfide (390°C) from the disulfide (500°C). Titanium trisulfide, iasoluble ia hydrochloric acid but soluble ia both hot and cold sulfuric acid, reacts with concentrated nitric acid to form titanium dioxide. 

Titanium monosulfide, TiS, assumes two forms, both of which are of the NiAs type. In 384, the packing of sulfur is of the ABAC type, with alternate layers of metal sites being fully occupied but the intermediate sites half filled. A series of intermediate phases Ti2+xS4 (0.2 < x < 1) also occurs. The trisulfide TiS3 is best represented as TiS (S2) . The trichalcogenides of Group IVA elements are typified...

A variety of metal sulfides and their mixtures have been employed to improve the friction stability, wear, and noise characteristics of friction materials. Commonly used sulfides are antimony trisulfide, molybdenum disulfide, tin sulfides, zinc sulfide, copper sulfides, titanium sulfide, and bismuth trisulfide. Sulfide lubricants are usually used to complement carbonaceous lubricants. Fluoride and molybdate additives are sometimes used to enhance the action of carbonaceous and sulfide lubricants. Examples of fluorides are calcium fluoride and cryolite. Sodium and calcium molybdates have been used in small amounts.
