Zirconium price per ton varies based on its form and type. The metal is available in several types. They include:
Zirconium Metal
Zirconium metal powder is the primary form used in multiple industries. The price reflects its purity. This is retrieved from the mineral zircon and its processing complexity. The cost of this form of zirconium is influenced by mining activities in regions such as Australia and South Africa. These countries are known to have rich deposits of the mineral.
Zirconium Alloys
Zirconium alloys are acquired by mixing zirconium with other metals like hafnium, niobium, and titanium. These are utilized in aerospace, chemical processing, and nuclear industries. The price per ton of such alloys tends to be higher than that of pure zirconium. This is due to the added value of improved mechanical properties and corrosion resistance.
Zirconium Chemical Compounds
Compounds like zirconium dioxide (zirconia) use the metal's oxide form. The price of zirconium chemicals depends on the compound used and the demand in the ceramic, dental, or refractory industries. Additionally, transportation and processing costs strongly influence the cost of these compounds' prices.
Zircon Sand
Unrefined zirconium is found in zircon sand. It is cheaper compared to processed zirconium. The price of sand per ton is driven by global demand for its usage in the production of zirconium. Often in ceramic applications, it's also impacted by the cost of extraction. These include labor and energy costs among other factors.
Zircon sand has several applications across a wide spectrum. Its key function is attributed to its ability to withstand extreme heat. For instance, in nuclear reactors, its resistance to high temperatures and its low absorption of neutrons make it a perfect candidate for zirconium cladding in fuel rods.
Zirconium is also known for its exceptional corrosion resistance properties. Due to this, it can be used in highly reactive environments for example in chemical processing plants. The metal is also widely used in the manufacturing of ceramic products due to its stability and the ability to enhance the durability and strength of ceramic materials. Therefore, making it indispensable in the refractory and ceramic industry in addition to offering a tough, heat-resistant material.
The unique properties of zirconium and its alloys come into play in various industrial processes, as explained below:
Zirconium finds diverse and extensive applications due to its outstanding properties. below is a discussion analyzing the common usage scenarios:
Zirconium in Jewelry and Watchmaking
Zirconium is increasingly popular in jewelry and watchmaking industry. This is due to its hypoallergenic nature and durability. Mainly, it is used in making rings, bracelets, and watch cases, as previously mentioned. Also, it has a similar appearance to titanium, thus giving it a sleek and modern look. It is lightweight and comfort-enhancing wear, making it a preferred option for long-lasting and stylish adornments.
Medical Applications of Zirconium
The biocompatibility of zirconium makes it ideal for various medical applications. For instance, it is used to manufacture surgical instruments, dental implants, and prosthetics. Its resistance to corrosion ensures long-term durability of the devices in body tissues. This accounts for why it is often used in implants where longevity is critical. In dentistry, zirconium oxide is used to create strong and aesthetically pleasing crowns and bridges.
Zirconium in Aerospace Engineering
The aerospace industry also greatly benefits from zirconium. Its high strength-to-weight ratio and ability to withstand extreme temperatures, for example, make it a valuable alloy component in aircraft and spacecraft. Moreover, in nuclear reactors, zirconium cladding is used for fuel rods due to its low absorption of neutrons. Consequently, enhancing efficiency and safety during fission operations.
Zirconium in Nuclear Power Plants
Thanks to its unique properties, zirconium is a critical component in the nuclear energy sector. The fuel rods in nuclear reactors are made of zirconium alloys. Usually, these alloys have a low absorption of neutrons, which allows for optimal fuel usage. In addition, zirconium's high resistance to corrosion and extreme temperatures makes it ideal for long-term applications in reactors.
Chemical Processing Industry
Corrosion-resistant zirconium materials are widely used in chemical processing plants. Particularly in facilities handling highly reactive substances, its ability to withstand aggressive acids and chemicals makes it ideal for manufacturing equipment, piping, and reactors. Therefore, its ability to form a protective oxide layer ensures the longevity and reliability of materials in demanding environments.
To make an informed decision on the type of zirconium alloy to buy, business owners need to check the following factors:
Material properties
Different zirconium alloys have varying characteristics. For instance, some alloys have higher resistance to corrosion. Others have greater strength. Some offer higher temperatures. Others have better conductivity. Therefore, buyers should stock alloys with suitable properties to cater to the customers' needs.
Purity and composition
Inclusions such as hafnium affect the properties of zirconium alloys. Depending on the percentage of such impurity alloys, they might be categorized as low-hafnium or high-hafnium zirconium alloys. Generally, low-hafnium alloys are used in nuclear processes. Therefore, buyers should understand the alloys' use and stock them in sufficient quantities.
Application
Different zirconium alloys are used in different industries. For instance, Zr-110 alloy is used for nuclear applications because of its low electron work. Other alloys such as Zr-102 and Zr-105are formulated into components used in chemical processing. Therefore, buyers should ensure they stock alloys suitable for various industrial applications.
Price and availability
At times, certain alloys may be more expensive than others, depending on their purity level or how they were obtained. Buyers should also quote reasonable prices while ensuring they get high-quality zirconium alloys.
Source reliability
If purchasing from an overseas supplier, buyers must ensure the alloy manufacturer is reliable and has been in the business for a long time. They must also ensure they get consistent and high-quality zirconium alloys.
Due to its high melting point, strong atomic bond with surrounding elements, and refractory nature, zirconium can withstand temperatures of more than 2000°C. This makes it ideal for high-temperature activities.
While zirconia and cubic zirconium are acquired from the same mineral, zirconium, cubic zirconium is synthesized in a laboratory, while zirconia is a natural stone. Also, cubic zirconia is shinier and has higher clarity than zirconia. Nonetheless, they are both durable and visually appealing. This is what gives them popularity in the jewelry-making industry.
Adding other metals such as hafnium, niobium, titanium, and chromium aids in refining the corrosion resistance properties of zirconium. These metals are often incorporated in small percentages, usually less than 4% to enhance the existing properties without affecting them.
They can request the suppliers' samples before placing an order. Alternatively, they can collaborate with third-party companies to conduct the quality checks.
Buyers can foster long-term collaboration by offering discount deals on bulk purchases and timely shipments. They also must ensure they adhere to the statutory zirconium alloy compositions and specifications IEC requirements.
