Why in News?

Hyderabad-based Nexon Geochem has signed a Memorandum of Understanding with Russia’s State Research and Design Institute of Rare Metal Industry, known as Giredmet, for joint research and development in rare and rare-earth metal processing and NdFeB rare-earth permanent magnet technologies. The partnership aims to establish an integrated rare earth oxide-to-magnet manufacturing platform in India, beginning with a scalable sintered NdFeB permanent magnet facility in Hyderabad.

What are NdFeB Permanent Magnets?

NdFeB magnets refer to Neodymium-Iron-Boron rare earth permanent magnets. They are among the strongest commercially available permanent magnets.
These magnets are called “permanent” because they retain their magnetic properties for a long period without requiring continuous electric current.
NdFeB magnets are important because they provide high magnetic strength in compact size. This makes them essential for advanced clean energy and mobility technologies.

They are used in:

Electric vehicle motors
Hybrid electric vehicle propulsion systems
Wind turbine generators
Offshore wind turbines
Electronics
Industrial automation
Defence and strategic technologies

About Nexon Geochem–Giredmet Partnership

Nexon Geochem is an advanced materials company based in Hyderabad. It aims to create a full-cycle platform from rare earth oxide inputs to finished magnet production.
The company has signed an MoU with Giredmet, Russia’s State Research and Design Institute of Rare Metal Industry.
Giredmet is part of Rosatom State Atomic Energy Corporation of Russia. It has nearly a century of expertise in rare metals research, high-purity separation, processing technologies and advanced material systems.

The MoU covers:

Joint R&D in deep-processing technologies for rare and rare-earth metal raw materials
Development of NdFeB rare-earth permanent magnet technologies
High-purity rare earth metals and compounds
Finished materials for electronics, chemical and nuclear industries
Analytical control methodologies
Scaling technologies from laboratory to pilot production
Joint academic and educational programmes
As an immediate goal, Nexon Geochem plans to set up a sintered NdFeB permanent magnet manufacturing facility in Hyderabad.
The company is targeting 1,200 mtpa production capacity of NdFeB permanent magnets by FY33.

Why Permanent Magnets are Strategically Important

Rare earth permanent magnets are not ordinary industrial inputs. They are strategic materials for the clean energy and digital economy.

1. Electric Mobility

Electric vehicles require high-performance motors. NdFeB magnets are used in electric synchronous traction motors for battery electric vehicles and hybrid electric vehicles.

2. Renewable Energy

Permanent magnets are key components in direct-drive generators used in wind turbines, especially offshore wind turbines.

3. Semiconductor and Electronics Ecosystem

Rare earth materials support several electronics and precision technology applications.

4. Strategic Supply Chains

Countries are trying to reduce dependence on concentrated global supply chains for rare earths and magnets.

5. Clean Energy Transition

Without reliable access to permanent magnets, growth in EVs, wind energy and advanced manufacturing can face supply bottlenecks.

India’s Demand and Market Potential

India’s demand for rare earth permanent magnets is increasing due to EV adoption and renewable energy deployment.

Indicator	2026	2031 Projection
Domestic consumption of permanent magnets	7,500 mtpa	12,500 mtpa
Market size	₹5,625 crore	₹20,625 crore
Average price	₹7,500 per kg	₹16,500 per kg
Growth rate	30% CAGR	18% CAGR

Significance of the MoU

1. Strengthening Critical Minerals Value Chain

The partnership can help India move from raw material dependence to value-added manufacturing in rare earth magnets.

2. Reducing Import Dependence

India currently depends heavily on imported high-performance permanent magnets. Domestic production can reduce vulnerability.

3. Supporting EV and Renewable Energy Sectors

NdFeB magnets are essential for electric vehicles and wind turbines. Local production can support India’s clean energy targets.

4. Boosting Hyderabad’s Advanced Manufacturing Profile

The proposed facility in Hyderabad can position Telangana as a hub for rare earth materials and advanced manufacturing.

5. India–Russia Technology Cooperation

The MoU reflects India–Russia cooperation beyond defence and energy into critical minerals and advanced materials.

6. Moving Towards Technological Sovereignty

The collaboration aims to build indigenous capability in rare earth processing, magnet production and material science.

Conclusion

The Nexon Geochem–Giredmet MoU is significant because rare earth permanent magnets are becoming critical to the future of clean energy, electric mobility and advanced manufacturing. By aiming to build an integrated rare earth oxide-to-magnet platform in Hyderabad, the partnership can help India reduce import dependence and strengthen its critical minerals value chain. If implemented effectively, it can support Atmanirbhar Bharat, energy transition, EV manufacturing and India’s long-term technological self-reliance.
