💡 Commercial Applications
Tungsten disulfide is a compound with various commercial and industrial applications. It is commonly used as a dry lubricant in high-temperature and high-pressure environments, such as in aerospace applications. Tungsten disulfide’s low friction coefficient makes it ideal for reducing wear and friction in machinery and equipment.
In addition to its commercial and industrial uses, Tungsten disulfide also has potential applications in the field of drug and medication delivery. Studies have shown that Tungsten disulfide nanoparticles can be used to deliver drugs to specific targets in the body, such as cancer cells. This targeted drug delivery system could help reduce side effects and improve the efficacy of treatments.
⚗️ Chemical & Physical Properties
Tungsten disulfide is a solid compound that appears as a dark gray to black powder. It has no distinct odor.
The molar mass of tungsten disulfide is approximately 248.07 g/mol, and its density is around 7.91 g/cm³. Compared to common food items like water (molar mass of 18.02 g/mol, density of 1 g/cm³) and sugar (molar mass of 342.3 g/mol, density of around 1.59 g/cm³), tungsten disulfide is much denser.
Tungsten disulfide has a high melting point of about 1250°C and a boiling point of around 1370°C. This is significantly higher than the melting and boiling points of common food items such as butter (melting point of 32-35°C) and milk (boiling point of 100°C).
Tungsten disulfide is insoluble in water and has a high viscosity. Compared to common food items like salt, which is soluble in water, and water itself, which has low viscosity, tungsten disulfide exhibits very different properties in terms of solubility and viscosity.
🏭 Production & Procurement
Tungsten disulfide, a compound composed of tungsten and sulfur atoms, is primarily produced through a chemical reaction involving the reaction of tungsten oxide and hydrogen sulfide gases at high temperatures. This process results in the formation of Tungsten disulfide powder, which can then be further processed into various forms for different applications.
Once Tungsten disulfide is produced, it can be procured through specialized chemical suppliers or manufacturers that specialize in producing and distributing inorganic compounds. The compound is typically transported in sealed containers to prevent contamination or degradation during transit. Special precautions may be necessary to ensure safe handling due to the compound’s potential toxicity.
Tungsten disulfide can also be procured in the form of lubricants or coatings, which are used in various industries such as aerospace, automotive, and electronics. These specialized products are often formulated with Tungsten disulfide nanoparticles for enhanced performance and durability. Transportation of these products may require special handling procedures to prevent leakage or contamination.
⚠️ Safety Considerations
Safety considerations for Tungsten disulfide involve its potential hazards when handled improperly. It is important to wear appropriate personal protective equipment, such as gloves and goggles, when working with this substance to prevent skin and eye irritation. Additionally, Tungsten disulfide should be stored in a cool, dry place away from incompatible materials to avoid any potential reactions or accidents.
Hazard statements for Tungsten disulfide include its potential to cause skin and eye irritation upon contact. Inhalation of the substance may also lead to respiratory irritation. It is important to handle Tungsten disulfide with care and follow proper safety precautions to avoid any adverse effects on health.
Precautionary statements for Tungsten disulfide involve measures to ensure safe handling and storage of the substance. It is recommended to keep the material in a tightly sealed container in a well-ventilated area to prevent exposure. In case of skin or eye contact, it is important to rinse thoroughly with water and seek medical attention if irritation persists. Additionally, proper training and awareness of the hazards of Tungsten disulfide are crucial for safe handling and use.
