КРУПНЕЙШИЕ ПРОИЗВОДИТЕЛИ ЦИРКОНИЯ В МИРЕ

THE LARGEST ZIRCONIUM PRODUCERS IN THE WORLD Zirconium is a chemical element with the symbol Zr and atomic number 40. It is a transition metal that is lustrous, grayish-white, and strong, known for its resistance to corrosion. Zirconium is primarily obtained from the mineral zircon (ZrSiO₄), which is found in igneous rocks and sand deposits, often associated with titanium minerals. Physical and Chemical Properties Appearance: Silvery-white, with a shiny surface. Density: 6.52 g/cm³. Melting Point: 1,855°C (3,371°F). Boiling Point: 4,409°C (7,968°F). Corrosion Resistance: Highly resistant to acids, water, and other corrosive environments. Reactivity: Zirconium does not react easily with oxygen at room temperature but forms a thin oxide layer when exposed to air, which protects it from further oxidation. Uses of Zirconium 1. Nuclear Reactors: Due to its low neutron absorption, zirconium alloys are used as cladding for nuclear fuel rods. 2. Aerospace Industry: Its heat resistance makes it valuable in jet engines and spacecraft. 3. Ceramics: Zirconium compounds, like zirconium dioxide (zirconia), are used in ceramics, dental implants, and as thermal insulators. 4. Chemical Industry: Used in equipment that handles corrosive chemicals, such as pumps, valves, and heat exchangers. 5. Jewelry: Zircon (zirconium silicate) is often used as a gemstone, with cubic zirconia being a popular diamond simulant. 6. Superconductors: Zirconium-niobium alloys are used in superconducting magnets. Occurrence Zirconium is the 20th most abundant element in the Earth's crust. It is primarily extracted from zircon sands, which are found in places like Australia, South Africa, Indonesia, Mozambique, Kenya, USA, Senegal, China, Vietnam, Madagascar, Brazil and India. Significance Zirconium’s combination of strength, heat resistance, and corrosion resistance makes it a critical material in modern industries. It plays a significant role in nuclear energy, aerospace, and advanced manufacturing. @CityGlobeTour @Geografico @klima-naturali-org    / @cityglobetour     / cityglobetour   http://www.megatimes.com.br http://www.klimanaturali.org ********************************* #youtubebe #cityglobetour #viralvideo #Geografico #CityGlobeStats #klima-naturali-org ***********************************
