Summary
DescriptionVanadium crystal bar and 1cm3 cube.jpg |
Deutsch: Reine Vanadium 99,9 % "crystal bars" nach dem Van-Arkel-de-Boer-Verfahren hergestellt, sowie für den Größenvergleich ein reiner (99,95 %) 1 cm3 Vanadium-Würfel. Das Bild zeigt unterschiedliche Kristallisationsstrukturen sowie auch eine an der Luft grünlich oxidierte Oberfläche das Vanadiums.
English: Purest Vanadium 99.9 %, three samples of a crystal bar showing different crystal textures and an on air greenish oxidized surface, made by crystal bar process (from the collection of Ethan Currens), as well as a highly pure (99,95 % = 3N5) 1 cm3 vanadium cube for comparison.
Español: Vanadio puro (99,9%): tres muestras de barra cristalina con diferentes texturas y una superficie verdosa oxidada al aire, así como un cubo de alta pureza (99,95% = 3N5) de 1 cm³ para comparar.
Français: Trois barres de vanadium cristallisé pur à 99,9 % obtenues par le procédé Van-Arkel-de-Boer (échantillons de la collection d'Ethan Currens). À titre comparatif, un cube de 1 cm3 de vanadium apparaît. Les pièces se trouvent sur une plaque de verre blanc.
Polski: Pręt z krystalicznego wanadu o czystości 99,9 % otrzymany w procesie jodkowym i oraz sześcian (1 cm3) wykonany z wanadu o czystości (99,95 %).
Română: Trei bare de vanadiu cristalizat de înaltă puritate (99,9%), obținute prin procedeul van Arkel-de Boer, prezentând texturi diferite ale suprafețelor. Acestora le este alăturat un cub de vanadiu de 1cm3 (puritate 99,95% = 3N5) pentru comparație.
中文: 纯度为99.9%的 钒,三个样品有着不同的结晶的纹理和一个在空气中有着绿色氧化膜的表面。右边是1个高纯(3.5N,即99.95%)的1立方厘米的钒立方体作为对比。
