Zirconium; unwrought, powders
HS v2017 Code: 810920
About zirconium; unwrought, powders
hs code 810920 covers the trade and production of unwrought zirconium and zirconium powders. Zirconium is a lustrous, gray-white, strong transition metal that is highly resistant to corrosion and has a wide range of industrial applications. The zirconium industry plays a crucial role in the manufacturing of various products, from nuclear reactors and medical devices to jewelry and ceramics, making it an important component of the broader global economy.
Production process
Zirconium is primarily produced through the Kroll process, which involves the reduction of zirconium chloride (ZrCl4) with molten magnesium or sodium. The resulting zirconium sponge is then melted and cast into ingots or other shapes. Zirconium powders are typically produced by atomizing molten zirconium or through the hydride-dehydride process, which involves the hydrogenation and subsequent dehydrogenation of zirconium metal.
Production inputs
The main inputs required for the production of zirconium and zirconium powders include zirconium-bearing ores, such as zircon (ZrSiO4) and baddeleyite (ZrO2), as well as various chemicals and energy sources needed for the extraction and refining processes. Specialized equipment, such as furnaces, reactors, and powder production machinery, are also essential inputs for this industry.
Production outputs
The primary outputs of hs code 810920 are unwrought zirconium and zirconium powders. These materials are then consumed by a wide range of industries, including 840110 Nuclear reactors, 901839 Medical devices, 711719 Jewelry, and 690290 Ceramic products. The zirconium industry also produces various intermediate products, such as zirconium compounds and alloys, which are further processed and utilized in other manufacturing sectors.
