  • Type I dielectric composition based on neodymium titanate
    Patent number: 4769354
    Abstract: A type I dielectric composition based on neodymium titanate is formed of a mixture comprising 58% to 78% by weight of neodymium titanate (Nd.sub.2 O.sub.3 -3TiO.sub.2), 10 to 21% by weight of lead titanate (PbTiO.sub.3), 5% to 14% by weight of barium titanate (BaTiO.sub.3), 4% to 15% by weight of barium zirconate (BaZrO.sub.3) and 0.2% to 1.2% by weight of yttrium oxide (Y.sub.2 O.sub.3).
