Rare Earth are not exactly rare, but refining them requires billion dollars refinery which only China has. Building such a refinery is expensive and takes a lot of time. And, China's rare earth are more concentrated. In other countries, like in Australia, they have shift through tons of materials just to get a .
Rare Earth Grinding Mill Machinery machine rare earth – Grinding Mill China. Impact of rare earth element added filters on the Xray beam spectra, Impact of rare earth element added filters on the Xray beam spectra: a Monte, and mean energy were investigated for a typical dental radiography machine.
how much better are rare earths than calcium tungstate when it comes to xray to light conversion efficiency 34 times better since rare earth phosphors absorb 50% more xrays than calcium tungstate, and convert 34 times as much absorbed xray energy into light energy, which type of phosphor is faster (more film density per mAs)
Sep 24, 2015· The second generation of Volt brings a significant mass reduction and increased performance, EV driving range and fuel economy while simultaneously reducing rare earth content in its traction electric motors. The electric propulsion system is .
Permanent Magnetic Separators. Rareearth magnetic circuits commonly exhibit a magnetic attractive force 20 to 30 times greater than that of conventional ferrite magnets. This development has provided for the design of highintensity magnetic circuits that operate energyfree and surpass the strength and effectiveness of electromagnets.
The price of rareearth metals used in neodymiumironboron (NdFeB) permanent magnets (PMs) has fluctuated greatly recently. Replacing the NdFeB PMs with more abundant ferrite PMs will avoid the cost insecurity and insecurity of supply.
In recent years, researchers in many fields try to reduce the use of rareearth materials in PM machines, facing the rising price of rareearth materials. Considering that iron poles replace half of PM poles in CP rotor, traditional PM machine with CP rotor can be a promising candidate for less rareearth PM machine.

The Puzzle Pieces. Another clue that the Model 3 motor is not using those rareearths in a conventional permanentmagnet motor design is that the car does not do regen all the way down to 0 miles per hour. For example, the Bolt has a conventional 3phase PM motor which allows it to do regen to 0 MPH.
