الحصول على السعرTantalum. At 800°–1200°C in a high vacuum, hydrogen separates from the metal and ductility is restored. At approximately 300°C, tantalum reacts with nitrogen to form a solid solution and the nitrides Ta 2 N and TaN; in a high vacuum at temperatures above 2200°C, the absorbed nitrogen separates from the metal.
الحصول على السعرTantalum is used in the electronics industry for capacitors and high power resistors. It is also used to make alloys to increase strength, ductility and corrosion resistance. The metal is used in dental and surgical instruments and implants, as it causes no immune response.
الحصول على السعرRare, pure, and strong, tantalum is dense, shatterproof and extremely malleable—characteristics that set it apart from other contemporary metals. In its natural state, tantalum is beautiful gray with a bluish tint, but a special patent pending ceramic glaze is applied to it when used as jewelry to give the metal a matte black look and enhance its scratchresistance.

الحصول على السعرTantalum is a greyish silver, heavy, and very hard metal. When pure, it is ductile and can be drawn into fine wire, which can be used as a filament for evaporating metals such as aluminium. Tantalum is almost completely immune to chemical attack at temperatures below 150°C, and is attacked only by hydrofluoric acid, acidic solutions containing the fluoride ion, and free sulphur trioxide.
