Neodymium is a lustrous silvery-yellow metal. Neodymium is one of the rare chemicals that can be found in houses in equipment such as televisions, fluorescent lamps, energy-saving lamps and glasses. Neodymium is one of the several metals in alloys commonly used in lighter flints. The most important alloys is neodymium, iron and boron (NIB), found to make excellent permanent magnets. As neodymium magnets are so strong, their uses are versatile. They are produced for both commercial and industry needs. These magnets are part of modern vehicles components, used in computer data storing and in loudspeakers. Neodymium is used in coloring glasses (didymium glass) able to adsorb the yellow sodium glare of the flame. This kind of glass is used to protect the eyes of welders. It is also used to tint glass attractive shades of purple.
