LaB6 (lanthanum hexaboride) single crystal
Single crystals
LaB6 single crystals are grown using a xenon-type floating zone furnaces manufactured by our company.
LaB6 single crystals have excellent electron emission properties and heat resistance, so they are used as electron sources for electron microscopes, etc.

Product Introduction
Features
LaB6 single crystals are a material with excellent electron emission properties and high heat resistance.
Compared to tungsten filaments, they are said to have 10 times the brightness and a lifespan 10 to 15 times longer. They also have a low work function.
LaB6 single crystals are primarily used as electron sources for electron microscopes and in electron beam lithography, but research into their use in space-related fields has also been progressing recently.
