Lanthanum Boride Powder, LaB6 Powder
Lanthanum hexaboride (LaB6) powder is a ceramic material that is composed of lanthanum and boron. It has a high melting point, high electrical conductivity, and is often used as an electron emitter. The powder is a fine, grayish-black powder that is insoluble in water and most acids. It is chemically stable and has good thermal stability, making it ideal for high-temperature applications.
LaB6 powder is used in a wide range of applications such as electron microscopy, x-ray diffraction, and other scientific instruments that require a high-performance electron source. It is also used in vacuum technology, where it can be used as a getter material to absorb trace gases.
The powder is typically prepared by mixing lanthanum oxide (La2O3) and boron carbide (B4C) powder and then heating the mixture to a high temperature in a reducing atmosphere. The resulting powder is then milled and sieved to produce a fine, uniform particle size.
Due to its unique properties, LaB6 powder is an important material in many high-tech applications and is widely used in scientific research and industrial manufacturing.
