Canadian deposits contain the heavy rare earth elements dysprosium
Working with the magnet company Intermetallics, materials scientist Satoshi Sugimoto of Tohoku University and colleagues recently developed fine-grained magnets that require 40 percent less dysprosium
Some experts predict that by 2015 there will be a shortage of neodymium, terbium, and dysprosium
, while supplies of europium, erbium, and yttrium could become tight.
Tiny quantities of dysprosium
can make magnets in electric motors lighter by 90 per cent, while terbium--which is soft enough to cut with a knife--is a key component of low-energy light bulbs, which use 80 per cent less electricity than traditional incandescent globes.
Hanchar, personal communication, 1995), reproduced in Figure 14, indicate that the major element responsible for the luminescence is the rare earth element dysprosium
, with possible contributions from terbium.
The newly developed magnet uses no terbium (Tb) or dysprosium
(Dy), which are rare earths that are also categorized as critical materials(3) necessary for highly heat-resistant neodymium magnets.
All these metals play different roles in the functioning of a smartphone - neodymium, terbium and dysprosium
, for example, are three rare metals that are used in providing phones the power to vibrate.

industry with a focus on the Chinese market.
(4 - 25 + 19 + 16 + 18 + 15 + 19) x (9 - 21 + 13) = 66
Readers will also recall that I dwelt on the discovery of dysprosium
on Alaska's Prince of Wales Island in my April 2014 article "U.S.
