Uses for the REEs that are not already covered in gregtech
Scandium - The alloy Al20Li20Mg10Sc20Ti30 is used in aerospace components due to its strength, lightweightness (not a real word but whatever), and hardness. Additive in mercury vapor lamps (a UV source)
Yttrium - Used in jet engines
Lanthanum - Used in Cerium-doped lanthanum bromide (also a scintillator), La3Te4 could be used in radioisotope power systems due to its conversion capabilities
Cerium - Used in Cerium-doped YAG, which is a scintillator used in particle detectors and emits light
Praseodymium Uses - Magnetic Refrigerator Coils (PrNi5), Didymium Glass
Promethium Uses - Atomic battery that lasts 5 years
Samarium Uses - Neutron absorber, used in X-ray lasers, samarium hexaboride is a topological insulator
Europium Uses - Television screens, good at phosphorescence (it gives red light)
Gadolinium Uses - Gd5(SiGe)4 could be a very good magnetic refrigerator coil. Used in green phosphors for TV screens. Is used in imaging technology when alloyed as Terbium doped gadolinium oxysulfide. Gadolinium oxyorthosilicate is a scintillator that detects neutrons.
Terbium Uses - Television screens, good at phosphorescence (it gives yellow and green light). Used in Terfenol-D for sensors and sonar systems. Best magnetostriction.
Dysprosium Uses - Neutron absorber in control rods. Dysprosium-cadmium chalcogenides are an infrared laser source. Used in hard disks and other data storage applications. Also a component of Terfenol-D. Used in Neodymium-iron-boron magnets in wind turbine generators. Used in didymium glass. DGG, DAG, and DyIG are used in magnetic refrigerators
Holmium Uses - At low temperatures it can get some very strong magnetic fields, used in YAG dopant for medical uses, infrared lasers for medical use, is as good as boron to absorb neutrons. Used in quantum computers as bit storage.
Erbium Uses - Used in control rods. Erbium-doped optical silica glass fibers are widely used in optical communications. Er3Ni alloys are used in cryocoolers for their unusually high heat capacity even at liquid helium temperatures. Er:YAG lasers have a 2,940 nm emission.
Thulium Uses - Holmium-chromium-thulium doped YAG is an overpowered laser medium. It operates in the infrared range and has uses in military applications and surgery. Can be bombarded with neutrons to produce Thulium-170, an X-ray source for cancer treatment and other detection.
Ytterbium Uses - Yb-169 and Yb-175 created from neutron bombardment of Ytterbium is also used in X-ray sources. It is used in the most accurate atomic clocks (exact to 18 digits after the decimal point). Can dope stainless steel to improve its mechanical properties. Yb3+ ions are used to dope laser mediums. Yb-171+ isotope ions are used as qubits in quantum computing and in Molmer-Sorensen gates
Lutetium - Lutetium Tantalate is ideal for X-ray phosphors. Lutetium aluminium garnet lenses are used in engraving wafers. Cerium-doped lutetium oxyorthosilicate is used in P.E.T. imaging.
Actinium - Ac-227 pressed with Beryllium is used as a neutron source. Can be used in RTGs. Used in cancer treatments. It is predicted that Actinium superhydrides are a room-temperature superconductor.
Thorium dioxide (AKA Thoria) can be used in ceramic fuel pellets, breeded into uranium-233, alloyed with tungsten electrodes to stabilize it, and used in high-quality lenses used in scientific instruments.
Uranium - Depleted uranium is used as radiation shielding due to its high density, higher than lead. Depleted uranium is used in ammunition and can penetrate heavily armored targets. Depleted uranium can also be used to strengthen plates. Both of these are due to how dense depleted uranium is. (might be useful for GCYW)
Neptunium - Np-237 is used to detect MeV-range neutrons. It could be used as fuel in a fast-neutron reactor or nuclear weapon. Np-237 can also be irradiated to make Np-238, which decays to Pu-238.
Plutonium - Used in nukes and RTGs
Americium - Can be pressed with beryllium to create a neutron source. Can be used in RTGs. Used to create heavier elements either by neutron bombardment or fusion. Is a source of gamma radiation and X-ray
Curium - Strong alpha emitters (6 MeV). Can be used as fuel in fast-neutron reactors. Can be used in RTGs. Were used on space probes as alpha particle X-ray spectrometer instruments.
Berkelium - Used to create californium from neutron irradiation, and heavier elements from fusion
Californium - Very strong neutron source. Used to make oganesson.
Einsteinium - Used in an attempt to make ununennium (element 119). Used in Surveyor 5 lunar probe
^^ All of these actinides can be used to make superheavy elements
