(LaB6 Products Produced by Wintrustek)

Lanthanum hexaboride (lanthanum boride, or LaB6) is an inorganic nonmetallic compound made up of low-valence boron and the uncommon metal element lanthanum. It is a refractory ceramic that can survive extreme temperatures and hard conditions. Lanthanum hexaboride ceramic has many applications due to its superior thermal, chemical, and electrical characteristics.

Features:

1. Consistent in Vacuum

2. High emissivities of electrons

3. Electrical conductivity that is good
4. Outstanding resistance to thermal shock
5. Outstanding resistance to oxidation and chemicals

Lanthanum hexaboride ceramics, with their unique physical and chemical properties, have important applications in many fields, primarily including the following applications:

Electron emission materials: Lanthanum hexaboride is an excellent thermionic electron emission material, characterized by low electron work function, high emission current density, high-temperature resistance, and good chemical stability. It is commonly used as the cathode in electron guns for devices such as electron microscopes, cathode ray tubes, electron beam welding machines, and ion implanters.

High-temperature thermocouple protection tubes: It exhibits excellent high-temperature resistance and chemical stability, enabling stable operation in high-temperature reducing atmospheres. It can be used as a protection tube for high-temperature thermocouples to measure temperatures in high-temperature environments.

Nuclear industry: Lanthanum hexaboride has strong neutron absorption capabilities and can be used as a neutron absorber material in nuclear reactors to control nuclear reactions.

Other industries: It can also be used to manufacture special refractory materials, high-temperature heating elements, and other components, playing a role in industrial equipment operating in high-temperature or special environments.
