When powerful neodymium magnets are used at high temperatures, such as for automotive applications, terbium and dysprosium are generally added to increase high-temperature coercivity.
I tried using neodymium magnet donuts to hold thread measuring triangles on my micrometer rather than those useless rubber thingies.
Even though the metal is distributed widely over the Earth's crust, mining and processing neodymium requires a lot of energy.
The isotope Hafnium 176 in contrast to its counterpart Neodymium 143 was transported by means of weathering into the oceans and became part of iron-rich sediments on the sea floor 2,700 million years ago," Dr.
Samples of the mid + heavy and neodymium - praseodymium products produced in May and July this year were submitted to the specialist analysts Laboratory Services International (LSI) in Rotterdam, Netherlands (part of the Intertek Group) for an independent confirmation of the purity achieved by the Peak pilot plant.
This combined neodymium with the equally difficult to pronounce praseodymium to produce glass which changes from amber brown to green, as you can see in the picture.
Demand for the magnets, made of such rare earths as neodymium and dysprosium, is expected to grow due to rising sales of hybrid and other eco-friendly cars.
The process starts with neodymium ore that is refined to neodymium oxide.
Adding neodymium atoms smothers some of the iron's magnetic strength but greatly improves its ability to resist demagnetization.
This work investigates the effect of the ratio between the DEAC and neodymium molar concentrations, polymerization temperatures, catalyst concentrations, and butadiene concentrations on the final MWD of obtained polymers and on the catalyst performance in butadiene polymerizations performed with a neodymium versatate catalyst.
This relates to the scarcity of the rare earth metal neodymium.
Toyota did not confirm what kind of engine it is working on, but industry observers say by using less magnets it would cut its demand for rare metals such as neodymium, which is mostly mined in China and used in hybrid and electric car motors.
