Titanium Sulfide Properties

About Titanium Sulfide TiS2 Powder:
Titanium disulfide is an inorganic compound. Titanium sulfide formula is TiS2. Brassy scaly crystal, metallic luster. Titanium sulfide density is 3.22 g/mL. Stable at room temperature, stable to water, dilute sulfuric acid and hydrochloric acid, but nitric acid and concentrated sulfuric acid can make it decompose sulfur. The lithium can be interbedded between the titanium disulfide layers, and the composition of the inner cambium compound LiTiS2 varies continuously between x=0 and 1, so it is an ideal non-stoichiometric compound. Titanium sulphide is a yellow or gray powder with an unpleasant odor and is used as a solid lubricant. Contact with the substance may cause burns to the skin, eyes, and mucous membranes. It can be toxic by ingestion, inhalation or absorption through the skin.

Titanium disulfide has a layered structure, each of which consists of a sulfur-titanium-sulfur interlayer connected by a weak van der Waals force. Crystals can be grown from titanium wires heated in sulfur vapor or synthesized by the reaction of titanium tetrachloride and hydrogen sulfide. The lithium can be interbedded between the titanium disulfide layers, and the composition of the inner cambium compound LiTiS2 varies continuously between x=0 and 1, so it is an ideal non-stoichiometric compound.
Titanium disulfide is an inorganic compound with the molecular formula TiS2. A highly conductive golden yellow solid belonging to a group of compounds called transition metal halogens, the stoichiometric unit ME2. TiS2 is used as a cathode material in rechargeable batteries.

How is Titanium Sulfide TiS2 Powder produced?
Titanium disulfide is prepared by the reaction of the elements around 500 °C.
Ti + 2 S → TiS2
It can be more easily synthesized from titanium tetrachloride, but this product is typically less pure than that obtained from the elements.
TiCl4 + 2 H2S → TiS2 + 4 HCl
This route has been applied to the formation of TiS2 films by chemical vapor deposition. Thiols and organic disulfides can be employed in place of hydrogen sulfide.
A variety of other titanium sulfides are known.
 

Applications of Titanium Sulfide TiS2 Powder:
The prospect of titanium disulfide as a cathode material for rechargeable batteries was proposed in 1973. Groups IV and V halogen compounds have attracted attention for their high electrical conductivity. The original described battery used a lithium anode and a titanium disulfide cathode. The energy density of the battery is high, the diffusion process of lithium ions to titanium disulfide cathode is reversible, and the battery can be charged.
Titanium disulfide was chosen because it is the lightest and cheapest chalcogenide.
Lithium-ion diffuses fastest in titanium disulfide.

The main problem is the degradation of the cathode after repeated use. This reversible insertion process allows the battery to charge. In addition, titanium disulfide is the lightest and cheapest of all the IV and V groups of layered dihalides.
In the 1990s, titanium disulfide was replaced by other cathode materials (manganese oxide and cobalt oxide) in most rechargeable batteries.
The use of TiS2 cathodes in solid-state lithium batteries most lithium-ion batteries use liquid electrolytes, which can pose safety concerns due to their flammability. A number of different solid electrolytes have been proposed to replace these hazardous liquid electrolytes.

For most solid-state batteries, high inter interface resistance reduces the reversibility of the intercalation process and shortens the service life. For TIS2, these undesirable interface effects are less of a problem. The power density of the all-solid-state lithium battery is 1000 W/kg and the maximum power density is 1500 W/kg in 50 cycles. In addition, the battery's average capacity dropped by less than 10% in 50 cycles. Although titanium disulfide has high conductivity, high energy density and high power, its discharge voltage is relatively low compared to other lithium batteries with high reduction potential cathode.


Storage Condition of Titanium Sulfide TiS2 Powder:
The damp reunion will affect TiS2 powder dispersion performance and using effects, therefore, Titanium Sulfide TiS2 Powder should be sealed in vacuum packing and stored in cool and dry room, the Titanium Sulfide TiS2 Powder can not be exposure to air. In addition, the TiS2 powder should be avoided under stress.

FAQs of Titanium Sulfide TiS₂ Powder:

Q: What is titanium sulfide used for?

A: Titanium disulfide (TiS₂) powders find applications across various industries due to their unique properties. They are particularly valued in the field of lithium-ion batteries as a cathode material, where TiS₂'s layered structure facilitates lithium ion intercalation and deintercalation, leading to high energy density and efficiency. In addition, TiS₂ can be used as a solid lubricant in high-temperature environments because of its low friction coefficient and thermal stability. The powder also serves as a catalyst or catalyst support in chemical reactions, enhancing the conversion rates of certain processes. Moreover, titanium sulfide's optical properties make it suitable for use in infrared reflective coatings and other optoelectronic devices. Its ability to conduct electricity while maintaining structural integrity at elevated temperatures makes TiS₂ an attractive material for developing advanced composites and functional materials.
 

Q: Is titanium sulfide safe for human exposure?

A: Exposure to titanium sulfide should be managed with appropriate precautions. While there is limited data on the health effects of TiS₂ specifically, fine particles of this compound may cause irritation to the respiratory system, eyes, and skin if not handled properly. Proper safety measures include wearing personal protective equipment (PPE) such as gloves, safety goggles, and a respirator when handling the powder, especially in situations where dust might become airborne. Adequate ventilation and adherence to occupational exposure guidelines are important to minimize risks. Always consult the Safety Data Sheet (SDS) provided by the manufacturer for detailed information on potential health impacts and safe handling practices.
 

Q: What is the formula and structure of titanium sulfide?

A: Titanium disulfide has the chemical formula TiS₂, indicating it consists of one titanium atom (Ti) and two sulfur atoms (S). This compound crystallizes in a layered structure, similar to that of molybdenum disulfide (MoS₂), which contributes to its remarkable properties, including its electrical conductivity and mechanical strength. The layers consist of sheets of titanium atoms sandwiched between two planes of sulfur atoms. This arrangement allows for strong bonding within the planes but weaker van der Waals forces between them, facilitating the sliding of layers past one another—a characteristic that makes TiS₂ effective as a lubricant. The crystal structure is key to its performance in various applications, especially those involving electrochemical processes and tribology.
 

Q: Can titanium sulfide be incorporated into composite materials?

A: Yes, titanium disulfide can be integrated into composite materials to enhance specific properties such as electrical conductivity, thermal stability, and mechanical strength. Composites containing TiS₂ benefit from these attributes while offering improved design flexibility and functionality. For example, incorporating TiS₂ into polymer matrix composites can lead to materials with enhanced thermal and electrical conductivity, making them suitable for electronic packaging or heat dissipation applications. When used as a reinforcing phase in metal or ceramic matrices, titanium sulfide can improve wear resistance and toughness, contributing to more durable components capable of operating under harsh conditions. Additionally, the layered structure of TiS₂ can be leveraged in developing advanced materials for energy storage, catalysis, and tribological applications. The versatility of titanium sulfide opens up possibilities for innovation across multiple industries, from electronics and aerospace to automotive and renewable energy sectors.
