What is Holmium Used for | Detailed Explanation

A Swedish chemist discovered a special material in the late 17th century and he named it holmium. Compared to other elements found so far in the world, holmium has its own characteristics and usages. It is involved in many parts of human life. Then what is holmium used for? Now let's find out some knowledge of the holmium element from the below passages.

Physical characteristics of holmium

Holmium is composed of 67 electrons from the physical structure. In its electronic layout, the first layer has 2 electrons, the second layer has 8 electrons, the third layer has 18 electrons, and the fourth layer has 29 electrons. Therefore, there are two lone pairs of electrons in the outermost layer.

Holmium’s density is nearly 9 g/cm³, this value is pretty big compared to other materials in the world. Holmium will be melted at about 1475℃ and it will be boiling at about 2696℃.

Holmium is a metal material with good magnetism. It can display ferromagnetism at pretty low temperatures, but as the temperature increases, its magnetism gradually disappears. The magnetic peculiarity of holmium gives it a place in the fields requiring magnetic substance and research on high-temperature superconductivity.

Holmium clearly has the capability to suck up and release lines in the visible spectrum. Its emission lines are mainly distributed in the green and red spectral range, which makes its compounds have typical colors of green or red.

Besides, people prefer to use holmium in related products because of its ideal thermal conductivity.

What are the biological features of holmium?

As a very rare material in nature, holmium’s content in living organisms is very small. The bio-availability of holmium is poor, which indicates that organisms have limited uptake and absorption capacity of holmium, and it is the main reason why the whole function of holmium in the human body is not fully understood.

Although there is limited knowledge of the physiological function of holmium, scientists find that holmium might participate in some important biochemical processes in the human body. Scientific research shows that holmium might be related to the health of bones and muscles, but the specific mechanism is still unclear.

The biological features of holmium in organisms are not fully clear. The current research mainly focuses on its possible physiological functions and toxic influence on organisms. With the continuous progress of science and technology, explorations of the biological features of holmium will also continue to deepen.

What is holmium used for?

As we mentioned in the above passages, holmium has a lot of special features, and people use it in many fields to make our lives more convenient. What is holmium used for in detail? Below are the detailed uses of holmium.

1.Holmium magnet: People prefer to use holmium as a material for manufacturing magnets because of its excellent magnetic features. Especially in the products that need high-temperature superconductivity, holmium magnets are applied to create superconductors to enhance their magnetic field.

2.Holmium glass laser: People use holmium to manufacture holmium glass lasers because holmium can add a special optical property to the glass. The reason why the holmium laser is said to be different from general laser technology is because its laser wavelength is stronger than other lasers, and the laser pulse is stronger, which is a type of laser technology. It can generate bubbles during the laser process, crush impurities, and effectively absorb impurities, reducing harm to the human body. As we all know, ordinary lasers have strong penetrating power and pose significant harm to the human body, while this type of holmium laser has shallow penetration and high safety performance.

3.Nuclear energy industry: holmium 165 is an isotope of holmium. It has a large neutron capture cross-section, which can control the neutron flux and adjust the power distribution of nuclear reactors.

4.Optical devices: Holmium is also applied in optical devices, such as photodetectors, modulators, optical waveguides in fiber optic communication, etc.

5.Fluorescent materials: Holmium compounds are generally used to produce fluorescent materials for manufacturing fluorescent lamps, fluorescent display screens, and fluorescent indicators.

6. Metal alloy: Holmium can be added to other metals to make alloys, and used to improve thermal stability, corrosion resistance, and metals’ welding performance. People put it in the manufacturing of aviation engines, automotive engines, and other chemical equipment.

Conclusion
