Indian material for magnet making
India aims to reduce its dependence on imports for rare earth magnets by developing cerium-based magnets, using abundant cerium resources found in its southern peninsular coast. The government has approved a ₹7,280 crore scheme to promote the manufacture of sintered rare earth permanent magnets in India.
India consumes about 6,000 tonnes of rare earth magnets, mostly imported, with consumption expected to double by 2030. The government has approved a ₹7,280 crore scheme to promote magnet manufacturing in India. The Bhabha Atomic Research Centre has developed technology for producing rare earth alloy powders at lower costs. Dr Raghavan Gopalan suggests using cerium, an abundant rare earth element in India, to make cheaper magnets. Cerium-based magnets can be used in mass-market applications like two-wheelers, appliances, and industrial motors. Research is focused on optimising alloy composition to minimise performance loss while retaining cost advantages.
