Produktbeschreibung

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Niobium pentoxide, is the chemical compound with the formula Nb2O5. It is used mainly in the production of capacitors, lithium niobate, and optical glass. It has many polymorphic forms all based largely on octahedrally coordinated niobium atoms. The polymorphs are identified with a variety of prefixes. The form most commonly encountered is monoclinic H-Nb2O5 which has a complex structure, with a unit cell containing 28 niobium atoms and 70 oxygen, where 27 of the niobium atoms are octahedrally coordinated and one tetrahedrally. There is an uncharacterised solid hydrate, Nb2O5.nH2O, the so-called niobic acid (previously called columbic acid), which can be prepared by hydrolysis of a basic solution of niobium pentachloride or Nb2O5 dissolved in HF.
