Tungsten yttrium electrodes are electrodes made of tungsten and yttrium. Similar to thoriated tungsten electrodes and ceriated tungsten electrodes, yttriated tungsten electrodes can be differentiated by their tip color. Tip color of tungsten yttrium electrodes is blue. Another point is that the yttrium content, in tungsten yttrium electrodes, content of yttrium ranges from 1.8% to 2.2%. Following is a table to show tungsten yttrium electrodes clearly.
Tungsten is the major content in tungsten yttrium electrodes. Tungsten is an element with properties of high melting point, high temperature resistance, high corrosion resistance, low thermal expansion and high hardness.
Yttrium has a silvery-metallic luster and ignites in air. Moon rocks are known to contain yttrium although on earth it occurs in the rarest minerals. Yttrium chemically resembles the lanthanides and can appear to gain a slight pink luster on exposure to light.
