Sodium metaniobate

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.
