| | | | ytterbium: Encyclopedia II - Thulium - Isotopes Naturally occurring thulium is composed of 1 stable isotope, Tm-169 (100% natural abundance). 31 radioisotopes have been characterized, with the most stable being Tm-171 with a half-life of 1.92 years, Tm-170 with a half-life of 128.6 days, Tm-168 with a half-life of 93.1 days, and Tm-167 with a half-life of 9.25 days. All of the remaining radioactive isotopes have half-lifes that are less than 64 hours, and the majority of these have half lifes that are less than 2 minutes. This element also has 14 meta states, with the most stable being Tm-164m (t½ 5.1 minutes), Tm-160m (t½ 74.5 seconds) and ...

| | | | ytterbium: Encyclopedia II - Xenotime - Occurrence Occurring as a minor accessory mineral, xenotime is found in pegmatites and other igneous rocks, as well as gneisses rich in mica and quartz. Associated minerals include biotite and other micas, chlorite group minerals, quartz, zircon, certain feldspars, analcime, anatase, brookite, rutile, siderite, and apatite. Xenotime is also known to be diagenetic: It may form as minute grains or as extremely thin (less than 10 µ) coatings on detrital zircon grains in siliciclastic sedimentary rocks. The importance of these diagenetic xenotime deposits in the radiometric dating of sedimentary rock ...

| | | | ytterbium: Encyclopedia II - Lutetium - Occurrence Found with almost all other rare-earth metals but never by itself, lutetium is very difficult to separate from other elements and is the least abundant of all naturally occurring elements. Consequently, it is also one of the most expensive metals, costing about six times as much per gram as gold.
The principal commercially viable ore of lutetium is the rare earth phosphate mineral monazite: (Ce, La, etc.)PO4 which contains 0.003% of the element. Pure lutetium metal has only relatively recently been isolated and is very diff ...

| | | | ytterbium: Encyclopedia II - Lutetium - Isotopes Naturally occurring lutetium is composed of 1 stable isotope Lu-175 (97.41% natural abundance). 33 radioisotopes have been characterized, with the most stable being Lu-176 with a half-life of 3.78 × 1010 years (2.59% natural abundance), Lu-174 with a half-life of 3.31 years, and Lu-173 with a half-life of 1.37 years. All of the remaining radioactive isotopes have half-lifes that are less than 9 days, and the majority of these have half lifes that are less than a half an hour. This element also has 18 meta states, with the most stable being Lu-177m (t½ 160.4 days), Lu-174m (t½ 142 days) and L ...

| | | | ytterbium: Encyclopedia II - Yttrium - Occurrence This element is found in almost all rare earth minerals and in uranium ores but is never found in nature as a free element. Yttrium is commercially recovered from monazite sand (3% content, [(Ce, La, etc.)PO4]) and from bastnasite (0.2% content, [(Ce, La, etc.)(CO3)F]). It is commercially produced by reducing yttrium fluoride with calcium metal but it can also be produced using other techniques. It is difficult to separate from other rare earths and when extracted, is a dark gray powder.
