Lanthanum hexaboride (LaB6) has a melting point of greater than 2400°C, a cubic crystalline structure and an extremely low electron work function of just 2.7eV. For this reason, LaB6 ceramic is used globally as a cathode in plasma-supported coating processes. We produce these cathodes with different geometries for a vast number of industrial and university applications.
