Hafnium has relatively small reserves in nature. It usually coexists with zirconium and is difficult to separate and extract, which limits its production and prevents it from being mass-produced like some common metals. Scarcity directly leads to higher prices.
• In nuclear reactors, hafnium can be used as a control rod material because it has good neutron absorption properties and can effectively control the rate of nuclear reactions. The nuclear industry has extremely high requirements for the purity and quality of materials, which also increases the production cost and price of hafnium.
• Hafnium has high melting point, good electrical conductivity and thermal conductivity, and can be used in the electronics industry to manufacture high-performance semiconductor devices such as field effect transistors. The manufacture of these high-end electronic devices requires high-purity hafnium, and its production process is complex and costly.
• Due to its outstanding high temperature resistance, hafnium can be used in the aerospace field to manufacture high temperature alloys for key components such as jet engines. These components need to work in extreme high temperature and high pressure environments, and the performance requirements of the materials are very strict, so the price of hafnium is correspondingly high.
The extraction and purification of hafnium from hafnium-containing minerals requires a complex process involving multiple chemical and physical processes. For example, high temperature smelting, chemical separation, electrolytic refining and other methods are usually required. These processes not only require a lot of energy and professional equipment, but also require strict production control and quality testing to ensure that the purity and quality of hafnium meet the requirements. This undoubtedly increases production costs, which in turn pushes up the price of hafnium.
