Reason for Adding Rare Earth Oxides to Tungsten Electrodes

Tungsten electrode picture

Metal tungsten, due to its high melting point, strong electron emission capability, and low vapor pressure, has become the preferred choice for thermionic emission materials. However, its high electron work function, elevated electrode tip temperature, and tendency for grain growth lead to unstable arc beams, difficult arc initiation, and a short service life in pure tungsten electrodes, limiting their use to alternating current welding. To overcome these drawbacks, manufacturers often add rare earth oxides with low electron work functions, such as lanthanum oxide, cerium oxide, and yttrium oxide, to pure tungsten materials. This not only increases the recrystallization temperature of the product but also enhances electron emission.

Requirements of Diamond Wire for Tungsten Core Wire

Tungsten wire images

As one of the primary cutting tools for high-hardness brittle materials, the quality of diamond wire depends not only on the production method, the size and distribution density of diamond particles, but also on the performance and thickness of the tungsten wire core. Generally, cutting wire produced using an electroplating process offers stronger cutting ability compared to that made with resin binders, primarily due to better diamond consolidation. The size of diamond particles should be moderate and evenly distributed; if the particles are too large, the cutting wire becomes too thick, increasing silicon wafer loss rates, whereas if they are too small, the cutting effectiveness decreases.
