Monazite is an important ore for thorium, lanthanum, and cerium. It is often found in placer deposits. India, Madagascar, and South Africa have large deposits of monazite sands. The deposits in India are particularly rich in monazite. Monazite is radioactive due to the presence of thorium and, less commonly, uranium.

Fig. 11 shows the XRD pattern of monazite powder after sintering at temperatures of 900–1150 °C for 2 h. It can be found that all the phases are single phases of La 0.332 Nd 0.334 Sm 0.334 PO 4 monazite. By observing the change of diffraction peak intensity, the half peak width of the XRD diffraction peak gradually narrows with increasing ...
Monazite is isostructural with huttonite (ThSiO 4 ), cheralite (CaTh (PO 4) 2 ), gasparite, and roosevelite ( Table 7) and displays variable degrees of solid solution among the endmembers ( Förster, 2006 ). Thus, natural monazite often contains thorium (Th) and arsenic (As) as major elements ( Hoshino et al., 2012b; Ondrejka et al., 2007 ).

In common with many other lanthanides, dysprosium is found in the minerals monazite and bastnaesite. It is also found in smaller quantities in several other minerals such as xenotime and fergusonite. ... It is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0. The sum ...
Most lanthanides are used as alloys for metals, ceramic purposes, and nuclear purposes. Lutetium is also considered a rare-earth element. These are a group of elements that are abundant on...

The AXO 4 monazite-type compounds form an extended family that is described in this review in terms of field of stability versus composition. All the substitution possibilities on the cationic and anionic sites leading to the monazite structure are reported. The phosphate, vanadate, chromate, arseniate, sulphate and silicate families are …
Uses Terbium is used to dope calcium fluoride, calcium tungstate and strontium molybdate, all used in solid-state devices. It is also used in low-energy lightbulbs and mercury lamps. It has been used to improve the safety of medical x-rays by allowing the same quality image to be produced with a much shorter exposure time.
Uses As a pure metal it is little used, because it reacts readily with water and air. Dysprosium's main use is in alloys for neodymium-based magnets. This is because it is resistant to demagnetisation at high temperatures. This property is important for magnets used in motors or generators.
The highest are found primarily in Brazil, India and China and are due to high concentrations of radioactive minerals in the soil. In Brazil, for example, the monazite sand deposits along certain beaches result in external radiation levels ~50 µGy/h. Natural radiation fields vary around certain average magnitudes everywhere.
The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays. The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 ...
This method is used by all rare-earth producers to separate mixtures into the individual elements with purities ranging from 95 to 99.9 percent. The ion-exchange process is much slower, but higher purities of more than 99.99999 percent (i.e., 5 …
Monazite – a rare earth phosphate containing a variety of rare earth minerals (particularly cerium and lanthanum) and 5-12% (typically about 7%) thorium. Xenotime – yttrium phosphate with traces of uranium and thorium. These mineral sands are in placer deposits which have been naturally concentrated by gravity.
