Sodium metaniobate

CAS number : 12034-09-2

Molecular weight :163.89

Molecular formula/chemical symbol :NaNbO3

Description :
 

Colorless crystals (room temperature three oblique lattice constant a=556.8pm, b=550.5pm, c=1551.8pm).As the temperature is lowered, sodium niobate has 5 crystal transformation: the non-polar phase at 604 ℃ into β phase (cubic perovskite structure), 562 ℃ into γ phase (false tetragonal, nonpolar), 354 ℃ into δ phase (rhombohedral crystal system, with anti ferroelectric resistance, dielectric constant of maximum density of 1800, 7.127 g/cm3), 200 ℃ to ε (monoclinic, with ferroelectric properties).Niobic acid sodium of antiferroelectric ceramics, point 222, point 480 ℃ Curie.

USES :

Sodium Niobium Oxideis generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.Titan produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTMtesting standards.Typical and custom packagingis available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
