镨(Pr) Basic knowledge introduction

About 160 years ago, Swede Mo Sangde discovered a new element from lanthanum, but it is not a single element, Mo Sangde discover the nature of such elements and lanthanum are very similar, they put their named "Pr-Nd" . "镨钕" Greek is the meaning of "twin". After more than 40 years, in 1885, the Austrian man Wells** successfully separated two elements from the "镨钕", one named "钕" and the other named It is "镨". This "twin" is separated, and the 镨 element also has its own vast world of talent. Niobium is a relatively large amount of rare earth element used in glass, ceramics and magnetic materials.
Widely used in bismuth: (1) 镨 is widely used in architectural ceramics and daily-use ceramics. It is mixed with ceramic glaze to make color glaze. It can also be used as glaze pigment alone. The pigment is light yellow and pure in color. Elegant. (2) Used to manufacture permanent magnets. Selection of inexpensive metal instead of pure neodymium, praseodymium, neodymium permanent magnetic material of metal, its antioxidant properties and significantly improved mechanical properties, the magnet can be processed into various shapes. Widely used in a variety of electronic devices and motors. (3) Used for catalytic cracking of petroleum . The preparation of a petroleum cracking catalyst by adding a Y-type zeolite molecular sieve in the form of a ruthenium-rich concentrate can improve the activity, selectivity and stability of the catalyst. China began to use industrial use in the 1970s, and its usage has been increasing. (4) 镨 can also be used for abrasive polishing. In addition, the use of germanium in the field of fiber is also becoming more widespread.
