The amount of permanent magnet that can be produced from a given quantity of NdPr oxide depends on several factors, including the composition of the magnet and the efficiency of the manufacturing process.

Here are some general considerations:

1. Composition of the Magnet: Permanent magnets typically contain neodymium (Nd), praseodymium (Pr), iron (Fe), and boron (B) in varying proportions. NdPr oxide is used as a precursor to supply the neodymium and praseodymium content.

2. Conversion Efficiency: During the manufacturing process, NdPr oxide is mixed with other elements, such as iron and boron, to form a magnet alloy. The yield of usable magnet material from the starting NdPr oxide can vary based on the efficiency of this conversion process.

Typical Yield: As a rough estimate, for every kilogram of NdPr oxide used, several kilograms of finished permanent magnet material can be produced. The exact yield depends on factors such as the magnet's size, shape, and magnetic properties required.

3. Industrial Scale: In industrial settings, production quantities are typically measured in tons of magnets produced per ton of NdPr oxide used. This ratio can vary widely based on the specific manufacturing techniques and the quality standards required for the magnets.

In summary, while there isn't a direct one-to-one conversion from NdPr oxide to finished magnets due to the alloying and processing steps involved, several kilograms of finished magnet material can typically be produced from each kilogram of NdPr oxide in industrial applications.


MOST IMPORTANTLY- Given your understanding of basic chemistry and the periodic table, you would also understand from third year chemistry, that yield is not directly proportional to theory. If only we could make yield 100%.

I would be very interested to read the process whereby you can produce a circa 1:3 ratio.

In practice, you don’t simply add atomic weights, there is loss.

With regard to above statement @ttroy I didn’t include Kia in that statement given the contract is with Hyundai/ Kia, so you can assume double that amount will eventuate.

But take that over to the ARU thread.
