摘要
Due to a combination of outstanding properties including high melting point,high density,low thermal expansion coefficient,low saturated vapor pressure and excellent thermal conductivity,tungsten(W)parts have been widely used as electrodes,heating elements,anti-scatter grids for Computed Tomography(CT)equipment,rocket nozzles and divertor materials for nuclear fusion[1].
