About Samarium Cobalt Magnets

Samarium-cobalt (SmCo) magnets are a type of rare-earth permanent magnet known for their exceptional thermal stability, corrosion resistance, and high coercivity. They were the first commercially available rare-earth magnets, introduced in the 1970s, and are particularly well-suited for high-temperature and harsh environment applications. SmCo magnets can operate at temperatures up to 300°C and have superior resistance. The global SmCo magnets market is expected to grow steadily in the coming years, driven by increasing demand from industries like aerospace, automotive, and electronics.

Properties of Samarium Cobalt Magnets

Samarium-cobalt magnets are extremely resistant to demagnetisation, have good temperature stability with maximum use temperatures up to 550°C, and exhibit excellent corrosion and oxidation resistance, often not requiring any surface coating. Samarium-cobalt magnets have a high energy density, with maximum energy products ranging from 128 kJ/m³ to 264 kJ/m³. They also have a high coercive force.

Manufacturing Process of Samarium Cobalt Magnets

The production of samarium-cobalt magnets begins with the creation of micron-sized samarium-cobalt powder through a metallurgical process. This powder is then compacted in a rigid steel mould under a magnetic field, which aligns the particles and imparts the desired magnetic orientation. The compacted magnets are then sintered and heat-treated to reach their fully dense condition. Next, the sintered magnets are machined to their final dimensional requirements and cleaned to remove any impurities. Finally, the finished samarium-cobalt magnets undergo a thorough inspection process before being packaged for distribution.

Synthesis of Samarium Cobalt Magnets

The synthesis of samarium cobalt magnets typically involves several key steps:

1.    Raw Material Preparation

Raw materials, primarily samarium oxide (Sm2O3) and cobalt (Co), along with other elements such as iron and copper, are weighed and mixed in the appropriate stoichiometric ratios. The common chemical formulas for samarium cobalt magnets are SmCo5 and Sm2Co17.

2. Alloy Preparation

The mixed raw materials are melted in an induction furnace under an inert atmosphere to form an alloy. This process is critical and requires precise control of temperature and atmospheric conditions to ensure the purity and homogeneity of the alloy.

Sm2O3 + 5Co → 2SmCo5 + 3/2O2

2Sm2O3 + 17Co → 4Sm2Co17 + 3O2

3. Milling

The alloy is then crushed and milled into a fine powder. This powder is crucial for the magnetic properties of the final product, as the particle size and distribution affect the magnet's performance.

4. Pressing

The powdered alloy is compacted in a die under high pressure in the presence of a magnetic field. This aligns the magnetic domains in the powder, which is critical for achieving the desired magnetic properties.

5. Sintering

The pressed compact is sintered at high temperatures in a vacuum or inert atmosphere furnace. Sintering enhances the magnetic properties by promoting diffusion and bonding of the particles.

SmCo5 (pressed) → SmCo5 (sintered)

Sm2Co17 (pressed) → Sm2Co17 (sintered)

6. Machining

After sintering, the magnets are machined to the desired dimensions. This step often requires diamond tooling because of the hardness and brittleness of the material.

7. Coating

To prevent corrosion, the magnets are usually coated with materials such as nickel, zinc, or epoxy.

8. Magnetisation

Finally, the magnets are magnetised by exposing them to a very strong magnetic field, which aligns all magnetic domains in the direction of the field, maximising the magnetic properties.

Applications and Drivers of Samarium Cobalt Magnets

Samarium cobalt magnets are commonly used in high-performance motors, actuators, generators, and electric motors, as well as in magnetic separation devices, traveling wave tubes, magnetic couplings, and magnetic bearings. These magnets also find use in sensor systems, drilling equipment, wind turbine equipment, and energy recovery systems. Additionally, they are employed in medical devices, missile components, industrial automation equipment, and pipeline inspection tools. Robotic arms, gyroscopes, accelerometers, particle accelerators, and sputtering deposition equipment also use these magnets.

The key drivers for using samarium cobalt magnets include their superior temperature stability, which allows them to operate from cryogenic temperatures up to 550°C. Moreover, samarium cobalt magnets can maintain their magnetic properties in high temperatures, humidity, and saltwater, making them an efficient choice across industrial, military, and medical applications.
