Nitride, Nitrided Oxide and Oxidized Nitride for Thin Dielectrics

MRS Proceedings, 1986
ABSTRACTIn this paper, comparisons of material and electrical parameters between qate and interpoly dielectrics consistinq of thermal oxides, nitrides, nitrided oxides and oxidized nitrides are reported. A range of dielectrics, 5 nm to 30 nm thick, are thermally grown using a matrix of oxidation cycles, ammonia concentration and nitridation ...

Aluminium nitride by carbothermal nitridation

Materials Science and Engineering: A, 1989
Abstract The different steps in the preparation of aluminium nitride powder by carbothermal nitridation of alumina are described. The parameters influencing the kinetics of the basic transformation of the oxide are listed and illustrated. The reaction rate depends on the degree of homogeneity of the solid mixture of raw materials or, adversely, is ...

The nitrides and oxide-nitrides of tungsten

Acta Metallurgica, 1954
Abstract A tungsten oxide-nitride with a composition close to the formula W.62N62O.38has been investigated by analytical and X-ray methods. It was obtained by reducing ammonium paratungstate or tungsten trioxide with ammonia, probably has metallic properties, and belongs to the interstitial compounds.

Homogeneous Dispersion of Gallium Nitride Nanoparticles in a Boron Nitride Matrix by Nitridation with Urea

Journal of Nanoscience and Nanotechnology, 2010
A Gallium Nitride (GaN) dispersed boron nitride (BN) nanocomposite powder was synthesized by heating a mixture of gallium nitrate, boric acid, and urea in a hydrogen atmosphere. Before heat treatment, crystalline phases of urea, boric acid, and gallium nitrate were recognized, but an amorphous material was produced by heat treatment at 400 degrees C ...

Niobium nitride/aluminum nitride superlattices

SPIE Proceedings, 1998
ABSTRACT DC reactive magnetron sputtering has been used to prepare niobium nitride/aluminium nitride superconductor/insulatorsuperlattices. Deposition conditions were optimized in order that multilayer fabrication could be achieved by simplecomputer control of the substrate positioning beneath each sputtering target.Transport measurements in the mixed ...

Preparation of Lutetium Nitride by Direct Nitridation

Journal of Materials Research, 2004
Lutetium nitride (LuN), an end member of a new quaternary system Si3N4–SiO2–Lu2O3–LuN, was synthesized by direct nitridation of a lutetium metal. The nitridation extent of the lutetium ingot (10 × 5 × 2 mm) reached about 97% by heating at 1600 °C for 8 h with an applied N2 pressure of 0.92 MPa; the initial shape of the bulk metal was maintained in the ...

Effect of NiS addition on nitridation of alumina to aluminum nitride using polymeric carbon nitride as a nitridation reagent

Ceramics International, 2016
Abstract We investigated the effect of adding nickel(II) sulfide (NiS) on nitridation of alumina (Al2O3) to aluminum nitride (AlN) using polymeric carbon nitride (PCN), which was synthesized by polymerization of dicyandiamide at 500 °C. The product powders obtained from nitridation of a mixture of δ-Al2O3 and NiS powders (mole ratio of 1:0.01) at ...

Investigation of nitriding directly in the nitriding process

Metal Science and Heat Treatment, 1982
1. We designed an apparatus and method of determining the phase composition at nitriding temperature. 2. At the beginning of the nitriding process (0.5 h) all phases corresponding to the Fe−N phase diagram are observed in Armco iron and the steels tested.
