One Kinds of Method of Manufacturing The Tungsten Electrode Yttrium

One kind of tungsten electrode manufacturing yttrium, characterized in that:

a.The doped yttrium nitrate aqueous solution spray evenly mixed with solid material way paratungstate (APT) or tungsten trioxide, heated drying into powder-coated tungsten yttrium;

b.On the prepared powder coated tungsten yttrium twice yttrium tungsten powder obtained after reduction by pressing, sintering temperature yttrium billet made ​​of tungsten;

c.Using the pressure processing method of the obtained forged tungsten billet made ​​of yttrium Yttrium tungsten electrode.
