Calcium Titanate Nanopowder or Nanoparticles, nanodots or nanocrystals are spherical or faceted high surface area oxide magnetic nanostructured particles. Nanoscale Calcium Oxide Particles are typically 20-80 nanometers (nm) with specific surface area (SSA) in the 15 - 50 m2/g range and also available with an average particle size of 100 nm range with a specific surface area of approximately 5 - 10 m2/g.
