We primarily use doped tungsten materials. For example, to produce WVM and WK65 we add small quantities of potassium. Potassium has a positive effect on the mechanical properties, in particular at high temperatures. The additives CeO 2 and La 2 O 3 ensure a low electron work function and consequently make tungsten suitable for use as hode
