Lanthanum is a soft, silvery-white, ductile and malleable metal. Lanthanum is the first member of the lanthanide group of the periodic table and is the 28th most common element in the earth's crust. It is soft enough to be cut with a knife and tarnishes quickly when exposed to air. When ignited, it burns easily. Lanthanum is one of the most reactive elements within this group and even reacts with water to give off hydrogen gas.

Although there is no commercial use of lanthanum alone, it is often used once alloyed with other elements. For example, lanthanum nickel is a good absorber of hydrogen gas and can absorb up to 400 times its own volume as a powder. This could prove useful for future use in hydrogen-powered cars as a way of storing the hydrogen gas. Today, however, it is mainly used as an additive to glass. It is used as a core material in carbon arc electrodes for film/photo studio lighting and floodlighting as it produces an emission spectrum similar to sunlight. When lanthanum oxide is added to glass for lens manufacturing, it improves the refractive index, with up to 40% of lanthanum oxide being consumed in the manufacture of optical glass. In these applications, in addition to increasing the refractive index, it improves the low colour dispersion and makes it more resistant to attack by alkalis. Finally, lanthanum salts contained in zeolite crystals are used in petroleum refining and help to stabilise the zeolite at high temperatures.
