Barium Titanate (Barium Titanium Oxide) Nanoparticles, nanopowder, nanodots or nanocrystals are spherical or faceted high surface area nanocrystalline alloy particles with magnetic properties. Nanoscale Barium Titanate Particles are typically 20-40 nanometers (nm) with specific surface area (SSA) in the 30 - 50 m2/g range and also available with an average particle size of 100 nm range with a specific surface area of approximately 7 m2/g.
