The name monazite is derived from the fact that it often comes in the form of a single crystal. It is a phosphate mineral containing strontium and barium. It is a rare earth mineral. The Chinese literary name is “phosphorus ore”. (Ce, Y, La, Th) PO4 is the main mineral for the extraction of strontium and strontium. The main source. It was discovered earlier that this mineral would emit cesium-232, which would later absorb slow neutrons and become uranium-233, while uranium-233 could be used as a nuclear fuel. The ore was found in 1940 synthesis and can be synthesized into 钚-239. Helium-239 is often used in nuclear reactors and nuclear weapons.铈 can be used as a material for alloys, flints, polishing, etc. In addition, many times monazus also contains strontium, so it can also be used to refine cockroaches.

The main source of monazite with economic exploitation value is alluvial or coastal sand deposits. The most important coastal sand deposits are along the coasts of Australia, Brazil and India. In addition, Sri Lanka, Madagascar, South Africa, Malaysia, Northeast China, Thailand, South Korea, North Korea and other places contain heavy sand deposits of monazite.

The production of monazite has been declining in recent years, mainly due to the radioactivity of the strontium in the ore, which is harmful to the environment.
