Hafnium Sponge - Global Industry Market Analysis Report 2020-2031

Hafnium sponge is a metal hafnium product with a sponge-like structure. Hafnium is in the same family as zirconium in the periodic table, which makes hafnium sponge similar to zirconium sponge in many properties and applications. However, due to its unique atomic structure and electronic properties, it shows its own characteristics and plays an important role in modern industry and scientific research.

The production process of hafnium sponge is relatively complicated. Its raw materials usually come from zircon sand. Because hafnium and zirconium are closely symbiotic in nature, almost all zirconium ores contain hafnium. First, the zircon sand must be pretreated, and hafnium and zirconium must be initially enriched by methods such as ore dressing. Subsequently, the enriched raw materials are converted into tetrachlorides, namely hafnium tetrachloride (HfCl₄) and zirconium tetrachloride (ZrCl₄), by chemical methods. This process is similar to the preparation of zirconium tetrachloride in the production of zirconium sponge, which is achieved by reacting with chlorine at high temperature and in the presence of coke. Since the chemical properties of hafnium and zirconium are extremely similar, separating the two becomes a key difficulty in the production of hafnium sponge. At present, the commonly used separation method is to use the difference in their distribution coefficients in different solvents to separate them by multi-stage extraction, such as using organic solvents such as methyl isobutyl ketone (MIBK) for extraction and separation. After multiple extractions and purifications, high-purity hafnium tetrachloride is obtained. Finally, the metal thermal reduction method is used, usually using active metals such as magnesium or sodium to reduce hafnium tetrachloride under high temperature and inert gas protection. The reaction equation is: HfCl₄ + 2Mg → Hf + 2MgCl₂, to generate sponge-like metal hafnium, and then after subsequent refining treatment, impurities are removed to obtain the final sponge hafnium product.

From the perspective of physical and chemical properties, the appearance of hafnium sponge is silver-gray, similar to that of zirconium sponge. Its density is as high as 13.31g/cm³, almost twice the density of zirconium sponge, which is due to its large relative atomic mass. The melting point of hafnium sponge is 2233℃, which is higher than that of zirconium sponge, and shows better high temperature resistance. In terms of chemical properties, hafnium sponge is also relatively active. It can react with oxygen at room temperature and form an oxide film on the surface. This oxide film protects the internal metal from further oxidation to a certain extent. It has good corrosion resistance to most acids and alkalis, especially in some oxidizing acids, and exhibits stable chemical properties. At the same time, hafnium has an extremely high neutron absorption cross section, which is in sharp contrast to zirconium sponge, making hafnium sponge have unique application value in the field of nuclear reactor control.

In the application field, hafnium sponge is mainly used in the nuclear industry. Due to its high neutron absorption cross section, it is widely used to manufacture control rods for nuclear reactors. During the operation of nuclear reactors, control rods are used to adjust the neutron flux, thereby controlling the rate of nuclear reactions. Control rods made of hafnium sponge can effectively absorb neutrons, accurately control the progress of nuclear reactions, and ensure the safe and stable operation of nuclear reactors. In the field of electronics, hafnium sponge can be used to manufacture semiconductor devices. Hafnium oxides (such as hafnium dioxide) have a high dielectric constant. In integrated circuit manufacturing, they can be used as gate dielectric materials to replace traditional silicon dioxide, which can effectively reduce the size of transistors, improve the performance and integration of chips, and promote the development of semiconductor technology. In addition, in the preparation of some special alloys, the addition of hafnium sponge can improve the performance of the alloy, such as improving the strength, hardness and high temperature resistance of the alloy. These alloys can be used in aerospace, high-temperature industry and other fields.

Compared with zirconium sponge, although hafnium sponge has similarities in appearance and some chemical properties, its application fields are also different due to differences in its density, melting point and neutron absorption cross section. Zirconium sponge is mainly used in fuel cladding and structural materials of nuclear reactors. Its low neutron absorption cross section is conducive to the efficient conduct of nuclear reactions; while hafnium sponge is used to manufacture control rods that control the rate of nuclear reactions due to its high neutron absorption cross section. In other fields, zirconium sponge is widely used in aerospace, chemical industry and other fields, while hafnium sponge plays a unique role in semiconductor manufacturing in the electronics field. With the continuous development of science and technology, the research and application of hafnium sponge are also expanding, and it is expected to play an important role in more fields in the future.
