A super magnet is a material having high total magnetization. |
The super magnets which can be made in India are Ca16Mn14Al2O41,Cr(FeO2)3, Fe12PbO19 etc. which have a high total magnetization greater than 120 Bohr magneton. India has 900 tonne of Calcium, 4 million tonne of Aluminium, 428583 kilotonne of manganese, 253150 kilotonne of Chromium, 28873661 kilotonne of Iron the form of Ores Haematite and Magnetite to manufacture the above magnets. |
The two high-strength magnets that can be produced in India are Triclinic Fe2O3 and Gd10S14O. India boasts 28873661 kilotonne of Iron the form of Ores Haematite and Magnetite and Gadolinium(Gd) in the form of 10.7 million tonne of Monazite from which Gd can be extracted. |
Rare-earth-free magnets which can be manufactured in India are Triclinic Fe2O3, LiFe5O8, Mn2O3 and Mn3(PO4)2 which have a high total magnetization of over 150 Bohr magneton. These magnetic materials do not include rare earth materials like Nd , Sm ,Eu etc. India also has plenty resources to manufacture the above magnets. |
The substitutes for Sm-Co magnets are Cr2O3 and Mn6PO12 which have similar properties of over 90 Bohr magneton, Tetragonal or Triclinic structure, space group symbol P1 and similar magnetic sites. |
The magnets which can be manufactured without rare-earth metals are Cr2O3, Fe2O3, Mn2O3 which have a high total magnetization. They are also Thermodynamically stable. |
The materials which are eco-friendly magnets are Fe5n, Fe6N which are made out of Iron Nitride which is rare-earth free. |
