Molybdenum (Mo) is a transition metal known for its high melting point, strength, and corrosion resistance, making it an indispensable material in modern industry. It is primarily used as an alloying element in steel and superalloys, where even small additions significantly enhance hardness, strength, and resistance to wear and corrosion. Its exceptional properties make molybdenum critical in energy, aerospace, automotive, and chemical industries.

One of the primary applications of molybdenum is in steel production. Adding molybdenum to steel improves its tensile strength, toughness, and ability to withstand extreme temperatures, while enhancing corrosion and wear resistance. These characteristics are essential for construction materials, pipelines, pressure vessels, and industrial machinery, where performance under harsh conditions is required. Stainless steel, in particular, benefits from molybdenum content, making it suitable for marine environments, chemical plants, and high-temperature applications.

Molybdenum is also a critical component in superalloys, which are used in jet engines, gas turbines,…

Antimony (Sb) is a silvery-gray metalloid known for its brittleness, corrosion resistance, and ability to form alloys with other metals. It is an essential element in a wide range of industrial applications, including flame retardants, batteries, semiconductors, and alloys, making it a critical material in modern manufacturing and technology. Its unique chemical and physical properties, combined with relative scarcity, have positioned antimony as a strategic commodity globally.

One of the primary uses of antimony is in flame retardant formulations. Antimony trioxide, the most common antimony compound, is widely used to enhance the fire resistance of plastics, textiles, coatings, and electronic components. By forming synergistic compounds with halogen-based flame retardants, antimony effectively inhibits combustion, helping manufacturers meet stringent fire safety standards across industries such as electronics, automotive, and construction.

Antimony is also an important component in lead-acid batteries, where small amounts of antimony are added to lead plates to improve mechanical…

Viscose, often referred to as rayon, is a semi-synthetic fiber derived from regenerated cellulose, typically sourced from wood pulp or cotton linters. Known for its silk-like appearance, softness, and breathability, viscose has become one of the most widely used fibers in the global textile industry. It bridges the gap between natural fibers like cotton and silk and fully synthetic fibers such as polyester, offering a balance of comfort, aesthetics, and affordability.

The production of viscose involves dissolving cellulose in chemicals such as sodium hydroxide and carbon disulfide, followed by regeneration into fine fibers. This process allows viscose to adopt a smooth texture and excellent draping properties, making it ideal for fashion, home textiles, and industrial applications. Its versatility is highlighted by its ability to be blended with other fibers, including cotton, wool, and polyester, enhancing the strength, durability, and functional performance of the final fabric.

One of the key advantages…
