Yttrium Micron Powder
Yttrium Micron Powder is an important chemical. Yttrium is a soft silver-colored metal that can be found in some so-called “rare earth” minerals, such as bastnasite and monazite, and in phosphate minerals such as xenotime, made up of up to 50% yttrium phosphate. Yttrium metal can be obtained by reducing yttrium fluoride with calcium metal. Yttrium has a concentration of 0.3 ppm in the earth's crust. The largest producers of this element are China, Russia, and Malaysia; while the largest reserves are in China, the CIS countries (including Russia) and the United States. Yttrium Micron Powder is used as an additive for alloys. Thus, it increases the resistance in magnesium and aluminum alloys. It is also used in the manufacture of radar microwave filters and as a catalyst in the polymerization of ethene. Yttrium-90, a radioactive isotope of this element, is used in medicine to treat certain types of cancer. Although yttrium does not have a biological role.
