Main Application Fields of Lanthanum Hexaboride Ceramic Materials


Lanthanum hexaboride LaB6 cathode material:
Lanthanum hexaboride has the characteristics of high emission current density and low evaporation rate at high temperature. Therefore, as a cathode material, it has gradually replaced some tungsten cathodes in industrial applications. At present, the main application fields of lanthanum hexaboride LaB6 cathode materials are as follows:
1 Microwave vacuum electronic devices and ion thrusters in the fields of military and space technology, and new technology industries such as display and imaging devices and electron beam lasers with high definition and high current emissivity required by civil and military industries. In these high-tech industries, the demand for low temperature, high uniform emission, high current emission density and high lifetime cathode materials has been very tight.
2 Electron beam welding industry. For electron beam welders, electron beam melting and cutting equipment. The cathode material should meet the requirements of high current density and low work function. The traditional equipment mainly uses tungsten cathode (the work function is too high, the current emission density is too small), which cannot meet the application requirements, and the LaB6 cathode replaces the tungsten cathode with its superior performance, and has been widely used in the electron beam welding industry. .
3 High-tech testing equipment industry. Due to its high brightness and long life, LaB6 cathode replaces the traditional hot cathode materials such as tungsten cathodes in electronic equipment such as electron microscopes, Auger spectrometers and electron probes.
4 Accelerator industry. LaB6 has higher ion bombardment stability than conventional tungsten and tantalum, and LaB6 cathode is widely used in accelerators of different structures such as synchrotrons and cyclotrons.
5 Discharge tube industry. The LaB6 cathode can be used in gas discharge tubes, laser tubes and magnetron type amplifiers.

As an electronic component in modern technology, LaB6 hexaboride is widely used in the civil and defense industries:
1 Electron emission cathode. Due to the low electron emission work, the cathode material with the highest medium-temperature emission current, especially the high-quality single crystal, is an ideal material for high-power electron emission cathodes.
2 High brightness point source. Used to prepare core components for electron microscopy, such as optical filters, soft X-diffraction monochromators, and other electron beam sources.
3 Highly stable and high life system components. Its excellent overall performance makes it suitable for use in a variety of electron beam systems, such as electron beam engraving, electron beam heat sources, electron beam torches and accelerators for engineering high performance components.

Boron Nitride Ceramic Properties

Boron nitride is a white solid ceramic material, with a nickname of "white graphite" because of its similar appearance and structure. Boron nitride ceramic is an excellent material which has low porosity, good thermal conductivity, low dielectric constant and superior dielectric strength. It is easily machined into complex shapes, and then ready for use without additional heat-treating or firing operations. Boron nitride has a variety of different variants: hexagonal boron nitride (h-BN), rhombohedral boron nitride (r-BN), cubic boron nitride (c-BN) and wurtzite boron nitride (w-BN). The most commonly used in the industry are h-BN and c-BN. H-BN & C-BN Hexagonal boron nitride, abbreviated as hBN, is an electron body having a layered structure similar to graphite. It has good lubricity, electrical insulation, thermal conductivity, and chemical resistance, and also has the ability to absorb neutrons. It is made of nitrogen (such as urea, melamine, etc.) and boron (b
