nickel ii chloride or just nickel chloride , is the chemical compound nicl 2. the anhydrous salt is yellow, but the more familiar hydrate nicl 2 ·6h 2 o is green. nickel ii chloride, in various forms, is the most important source of nickel for chemical synthesis. the nickel chlorides are deliquescent, absorbing moisture from the air to form .
nickel-56 is produced in large quantities in supernovas and the shape of the light curve of these supernovas display characteristic timescales corresponding to the decay of nickel-56 to cobalt-56 and then to iron-56. nickel-58 is the most abundant isotope of nickel, making up 68.077% of the natural abundance.
nickel electroplating is a technique of electroplating a thin layer of nickel onto a metal object. the nickel layer can be decorative, provide corrosion resistance, wear resistance, or used to build up worn or undersized parts for salvage purposes.
cobalt is a chemical element with the symbol co and atomic number 27. like nickel, cobalt is found in the earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. the free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.
cobalt-60 60 co , is a synthetic radioactive isotope of cobalt with a half-life of 5.2713 years. it is produced artificially in nuclear reactors. deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope 59 co.
lithium nickel manganese cobalt oxides abbreviated li-nmc, lnmc, nmc or ncm are mixed oxides of lithium, nickel, manganese and cobalt.they have the general formula lini x mn y co z o 2.the most important representatives have a composition with x y z = 1 and are closely related to lithium cobalt iii oxide licoo 2 and have a layered structure like these.. nowadays, nmcs they are among .
the deprotonation of cobalt iii ammine-halide complexes, e.g. cocl nh 3 5 2 labilises the co-cl bond, according to the sn1cb mechanism. applications. metal ammine complexes find many uses. cisplatin ptcl 2 nh 3 2 is a coordination compound containing two chloro and two ammine ligands. this is a drug used in treating cancer.
nickel titanium, also known as nitinol, is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages. different alloys are named according to the weight percentage of nickel, e.g. nitinol 55 and nitinol 60. it exhibits the shape memory effect and superelasticity at different temperatures.
electroless nickel immersion gold enig is a type of surface plating used for printed circuit boards.it consists of an electroless nickel plating covered with a thin layer of immersion gold, which protects the nickel from oxidation.. enig has several advantages over more conventional and cheaper surface platings such as hasl solder , including excellent surface planarity particularly .
the lithium nickel cobalt aluminium oxides nca are a group of substances comprising metal oxides.some of them are important due to their application in lithium ion batteries.ncas are used as active material on the positive pole which is the cathode when the battery is discharged . ncas are mixed oxides comprising the cations of the chemical elements lithium, nickel, cobalt and aluminium.
the isotopes of cobalt range in atomic weight from 47 co to 75 co. the primary decay mode for isotopes with atomic mass unit values less than that of the most abundant stable isotope, 59 co, is electron capture and the primary mode of decay for those of greater than 59 atomic mass units is beta decay.
alkaline electroless nickel boron coating nib is an autocatalytic coating process.the coating is deposited from an aqueous solution which contains either an alkylamineborane or sodium borohydride as a reducing agent, a source of nickel ions, a buffer, complexant, and control chemicals. alkaline nickel boron coatings are classified as type 1, nickel thallium boron or type 2, nickel boron.
clarification needed electroless nickel plating uses hypophosphite as the reducer while plating of other metals like silver, gold and copper, typically use low-molecular-weight aldehydes. a major benefit of this approach over electroplating is that the power sources and plating baths are not needed, reducing the cost of production. this .
alnico is a family of iron alloys which in addition to iron are composed primarily of aluminium al , nickel ni and cobalt co , hence acronym al-ni-co.they also include copper, and sometimes titanium.alnico alloys are ferromagnetic, and are used to make permanent magnets.before the development of rare-earth magnets in the 1970s, they were the strongest type of permanent magnet.
layers of gold thinner than 0.5 µm 0.02 thou also dissolve completely into the solder, exposing the underlying metal usually nickel to the solder. impurities in the nickel layer can prevent the solder from bonding to it. electroless nickel plating contains phosphorus. nickel with more than 8% phosphorus is not solderable.
electroless nickel plating is self-catalyzing process, the resultant nickel layer is nip compound, with 7–11% phosphorus content. properties of the resultant layer hardness and wear resistance are greatly altered with bath composition and deposition temperature, which should be regulated with 1 c precision, typically at 91 c.
dichlorobis triphenylphosphine nickel ii is a metal phosphine complex with the formula nicl 2 p c 6 h 5 3 2.it is a dark blue crystalline solid. it is used as a catalyst for organic synthesis.. synthesis and structure. dichlorobis triphenylphosphine nickel ii is a commercially available reagent.
electroless plating, also known as chemical or auto-catalytic plating, is a non-galvanic plating method that involves several simultaneous reactions in an aqueous solution, which occur without the use of external electrical power.
