 Application areas: 

 For three-color phosphor powder in the green activator, such as Tb-activated phosphate matrix, terbium-activated silicate matrix, terbium-activated cerium magnesium aluminate matrix, in the excited state are given the green light; magnetic optical storage materials, with the Tb-Fe amorphous films developed magneto-optical discs, for computer storage devices, storage capacity increased by 10 to 15 times; magneto-optical glass, Faraday glass containing terbium is to create the widely used laser technology rotators, isolators and circulators of the key materials; Tb Dy Fe magnetostrictive alloy (TerFenol) terbium dysprosium iron for sonar, has been widely used in a variety of areas, from the fuel injection system, liquid control valves, micro- Navigate to the mechanical actuator, regulatory agencies and the Space Telescope regulators and other areas of the wing
