Description


Bryce Art TANTALE Le tantale a été découvert par Anders Gustaf Ekeberg (SE) en 1802. Étymologie du nom: vient de Tantale, père de Niobe, dans la mythologie grecque. Le tantale a des propriétés voisines de cells du niobium. Le tantale est un métal rare, gris et lourd, dur mais ductile, avec une température de fusion élevée. Sur les surfaces en contact avec l'air se forme un film d'oxyde qui résiste à la corrosion. Il réagit avec l'acide fluorhydrique et les bases fondues. Il brûle dans l'air. On trouve toujours le tantale avec le niobium, principalement dans le minerais de tantalite. Le tantale est un substitut économique du platine. Le pentoxyde de tantale est utilisé dans les condensateurs et les lentilles d'appareils photos afin d'augmenter la réfraction. Ce métal et ses alliages résistent à la corrosion et à l'usure: ils sont utilisés pour fabriquer des appareils chirurgicaux et dentaires. LE PLAN NORD Le Chantier d'une Génération Site Officiel LE PLAN NORD en VIDÉO TANTALUM Tantalum was discovered by Anders Gustaf Ekeberg (SE) in 1802. The origin of the name comes from the Greek word Tantalos meaning father of Niobe in Greek mythology, (tantalum is closely related to niobium in the periodic table). It is a rare, grey, heavy, hard but ductile, metal with a high melting point that reacts with HF and fused alkalis. Metal ignites in air and exposed surfaces form corrosion resistant oxide film. Tantalum is always found with niobium but occurs chiefly in the mineral tantalite. It is often used as an economical substitute for platinum. Tantalum pentoxide is used in capacitors and in camera lenses to increase refracting power. It and its alloys are corrosion and wear resistant so it is used to make surgical and dental tools. LE PLAN NORD The Project of a Generation TÁNTALO El tántalo (o tantalio) fue descubierto en 1802 por el sueco A.G. Ekeberg cuando estudiaba una muestra de un mineral de Finlandia conocido hoy como tantalita. Es recibió su nombre en honor de Tántalo, héroe mitológico griego. Es un metal de color blanco plateado, maleable y dúctil. En frío resulta resistente a los agentes químicos. Se usa para aleaciones resistentes a la corrosión en plantas químicas y en aeronáutica. En tecnología médica se emplea como material de clavos para huesos, tornillos para mandíbulas e injertos para articulaciones. LE PLAN NORD The Project of a Generation TANTALIO Il tantalio deriva da Tantalo mitico re Greco. Esso è un metallo duro, pesante, grigio,duttile, malleabile. Ha un alto punto di fusione. Si trova, in tracce, nella tantalite (FeTa2O6) e nella olovotantalite [Ta,Nb,Sn,Fe,Mn)O2]. E'usato in leghe metalliche. Il suo pentaossido è usato in capacitori e in lenti fotografiche in quanto incrementa l'indice di rifrazione del vetro. LE PLAN NORD The Project of a Generation Thanks Magik
