Lanthanum nickel oxide with the chemical formula of LaNiO3 is an important perovskite-type oxide with metallic conductivity. Lanthanum nickel oxide is a ternary compound with unique chemical and physical properties. It shows an extended range of oxygen-deficient compositions, an uncommon intrinsic n-type metallic conductance, a perovskite crystal structure and thermal and chemical stability. These characteristics make LNO a technologically important perovskite oxide electrode in many potential applications such as ferroelectric thin film capacitors, solid oxide fuel cells, nonvolatile ferroelectric random access memories and multilayer actuators. Furthermore, LNO films have potential to be used as oxygen pressure and ethanol active sensing layers. Also, the reduced La–Ni mixed oxides are reported to be good catalyst precursors to synthesized organic compounds and to grow large amounts of regular diameter distribution controlled carbon nanotubes.

Cobalt, iron and boron get together to form an alloy and this alloy can be used as a sputtering target. Let’s look at the applications that cobalt, iron and boron alloy can be used. Boron alloy with transition metals like cobalt iron boron have many attractive properties, including high melting point and hardness, good wear and corrosion resistance, excellent electrical conductivity, and resistance to attack by molten metals. There therefore appears to be significant scope for enhancing surface properties of metals and ceramics by applying coatings constituted from these materials. Also, there are many applications which require a high ultimate tensile strength, high thermal stability and ease of fabricability. All these properties can be obtained by using alloys. For example, metal ribbons used in razor blade applications usually undergo a heat treatment of about 370° C for about 30 min to bond an applied coating of polytetrafluoroethylene to the metal. Likewise, metal strands us...
