Tantalum Overview The texture of the tantalum is very hard and the hardness can reach 6-6.5. Its melting point is as high as 2996 °C, only after carbon, tungsten, rhenium, and osmium. Tantalum is malleable and can be drawn into a thin foil. Its coefficient of thermal expansion is very small, and it only expands by 6.6 parts...Continue Reading

We have previously made a brief introduction of Five Sputter Coating Technologies, including unbalanced magnetron sputtering, radio frequency sputtering (RF sputtering), direct current magnetron sputtering (DC sputtering), mid-frequency alternating current magnetron sputtering (AC sputtering), and reactive magnetron sputtering. In this article, we are going to talk about direct current (DC) sputtering in detail. To begin...Continue Reading
