Graphite flakes can cost around US$0.9/kg carbon. [20] Price of synthetic industrial diamond for grinding and polishing can range from 1200 to 13 300 USD/kg, while cost per weight of large synthetic diamonds for industrial applications can be on the order of million dollars per kilogram.

Neodymium is used in the electric motors of hybrid and electric automobiles [51] and in the electricity generators of some designs of commercial wind turbines (only wind turbines with "permanent magnet" generators use neodymium). [55] For example, drive electric motors of each Toyota Prius require one kilogram (2.2 pounds) of neodymium per ...
Inventor Masato Sagawa demonstrating a NdFeB magnet's force with 2 kg bottle. A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. [1] They are the most widely used type of rare-earth magnet.
A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements. Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets. The magnetic field typically produced by rare-earth ...

Neodymium compounds are compounds formed by the lanthanide metal neodymium (Nd). In these compounds, neodymium generally exhibits the +3 oxidation state, such as NdCl 3, Nd 2 (SO 4) 3 and Nd (CH 3 COO) 3. Compounds with neodymium in the +2 oxidation state are also known, such as NdCl 2 and NdI 2. Some neodymium compounds have colors that vary ...
In magnetics, the maximum energy product is an important figure-of-merit for the strength of a permanent magnet material. It is often denoted (BH)max and is typically given in units of either kJ/m3 (kilojoules per cubic meter, in SI electromagnetism) or MGOe (mega- gauss - oersted, in gaussian electromagnetism). [1][2] 1 MGOe is equivalent to 7 ...
Neodymium(III) oxide or neodymium sesquioxide is the chemical compound composed of neodymium and oxygen with the formula Nd 2 O 3. It forms very light grayish-blue hexagonal crystals. [ 1 ] The rare-earth mixture didymium , previously believed to be an element , partially consists of neodymium(III) oxide.
