LaB6  Powder Description

Lanthanum Boride, also called Lanthanum Hexaboride or LaB6, is a inorganic chemical and refractory ceramic material. It has a high melting point of 2210 °C, and is insoluble in water and hydrochloric acid. It has a low work function and one of the highest electron emissivity known, and is stable in vacuum. Therefore, the principal use of lanthanum hexaboride is as a coating deposited by physical vapor deposition of hot LaB6 filament, or to manufacture hot cathodes made of LaB6 single crystals. It is also used as a size/strain standard in X-ray powder diffraction to calibrate instrumental broadening of diffraction peaks.

Much better the I bought in other places

Perfect! I love them!

Will definitely purchase again.

Better than the ones I bought from another big wholesale company.
