B22F 1/02
C22C 1/05
US Classification:
75369, 75255, 75343, 75363, 75374
Abstract:
An efficient process for producing fine nickel powder, capable of metallizing the powder at low temperature to prevent its sintering, and fine nickel powder produced by the process, composed of particles having a flat shape, diameter of limited variations and uniform thickness, and suitable for internal electrodes for laminate ceramic capacitors of high electric capacity. The process comprises a step for forming a nickel compound coated with gelatin by adsorbing gelatin on preformed nickel compound particles with different size and shape (Step (A)), and another step for converting said nickel compound coated with gelatin into fine particles containing metallic nickel and nickel oxide by heating the nickel compound coated with gelatin produced in Step (A) in an inert gas atmosphere (Step (B)). It may include an additional step (Step (C)), subsequent to Step (B), for completely reducing nickel oxide in said fine particles by heating at temperature lower than that for Step (B) in a reducing gas atmosphere.

Krishna Balantrapu - Marlborough MA, US
Brendan P. Farrell - Cranston RI, US
Assignee:
Umicore AG & Co. KG - Hanau-Wolfgang
International Classification:
A61K 9/14
A61K 31/28
A61K 33/24
A61K 33/26
A61K 33/38
US Classification:
424617, 514495, 514492, 424489, 424618, 424646, 424649, 977773, 977777
Abstract:
The present invention is directed to a method for preparing colloidal dispersions of precious metal nanoparticles selected from the group consisting of Pt, Au, Pd, Ag, Rh, Ru and mixtures or alloys thereof, and to a method for isolating such precious metal nanoparticles from these colloidal dispersions. The colloidal dispersions are prepared by reducing suitable precious metal precursor compounds in aqueous alkaline solutions at reaction temperatures between 40 and 70 C. and a pH≧12. 0 in the presence of polysaccharides with average molecular weights (M) in the range of 300,000 to 1,000,000. The precious metal nanoparticles are isolated after decomposing the polysaccharide by heating the colloidal dispersions to temperatures >80 C. The nanoparticles can be used for the manufacture of core/shell-type catalyst materials and for electronic, decorative and medical applications.

Systhetic Whitener Pigment

View page
US Patent:
52485560, Sep 28, 1993
Filed:
Nov 15, 1991
Appl. No.:
7/792791
Inventors:
Egon Matijevic - Potsdam NY
Peter Hsu - Potsdam NY
Manfred R. Kuehnle - New London NH
International Classification:
B32B 516
B32B 1502
US Classification:
428403
Abstract:
Whitener pigment particles that offer good hiding power consist of particles having a uniform shape (preferably spherical) and varying only slightly in dimension. The particles consist of an inexpensive, readily manufacturable core material which is surrounded by one or more thin, concentric layers or shells, one of which is titania. The core provides the central mechanical support for the shells. In addition to the titania shell, layers can be added to provide compatibility with the carrier in which the particles are dispersed and promote phase transformation. Also described is a production method and apparatus for generating large quantities of the particles.

7/540930
Inventors:
Egon Matijevic - Potsdam NY
Nobuo Kawahashi - Yokkaichi, JP
Assignee:
Clarkson University - NY
Japan Synthetic Rubber Co., Ltd.
International Classification:
B01J 1302
B05D 724
US Classification:
42721331
Abstract:
Spherical particles include a core of a polymer and a metal compound covering the polymer core. These particles may be formed by homogeneously dispersing particles of a polymeric compound in an aqueous solution of a hydrolyzable metal salt to form a uniform metal layer around the spherical particles. The spherical particles can also include a core of carbon and a metal compound covering the carbon core or the particles can have a hollow core prepared by heating spherical polymer particles coated with a metal compound to a temperature of 150. degree. C. or higher in the presence of oxygen to completely decompose the polymeric compound. These spherical particles are useful in electronic materials, magnetic materials and the like.

Dyed Silica Pigments And Products Made From Same

View page
US Patent:
58853430, Mar 23, 1999
Filed:
May 30, 1997
Appl. No.:
8/865722
Inventors:
George J. Cernigliaro - Freeport ME
Egon Matijevic - Potsdam NY
Daniel Y. Pai - Millbury MA
Todd A. Richardson - Lowell MA
Assignee:
Shipley Company, L.L.C. - Marlborough MA
International Classification:
C07B 1404
US Classification:
106482
Abstract:
The adsorption of cationic dyes on nanosize negatively charged silica particles to form colored pigments is disclosed. The dyes are chemisorbed and their uptake is controlled by the strong chemical reaction between the negative surface of the adsorbent silica particles preferably with sodium counter ions and the positive charge of the dyes. The prepared pigments are useful in the formation of color films and their optical properties are described. Photoresists using nanosized pigments are also disclosed herein which are useful in making color filters for liquid crystal displays.

Electroplating Process And Composition

View page
US Patent:
60179678, Jan 25, 2000
Filed:
Apr 1, 1996
Appl. No.:
8/626671
Inventors:
Egon Matijevic - Potsdam NY
Matthias Schultz - Jena, DE
Wade Sonnenberg - Upton MA
John J. Bladon - Framingham MA
Patrick J. Houle - Framingham MA
Thong B. Luong - Springfield MA
Assignee:
Shipley Company, L.L.C. - Marlborough MA
International Classification:
B01J 1300
US Classification:
516 96
Abstract:
The invention relates to a metal sulfide dispersion used for electroplating nonconductors such as substrates used for the formation of a printed circuit board. A printed circuit board made using the dispersion could have metallized through-holes comprising electrodeposited copper on the walls of the holes with an adsorbed layer of metal sulfide particles between the circuit board base material and the copper on the walls of the through-holes. The metal sulfide is characterized by spherical particles having a mean diameter of less than 100 nanometers and a particle size distribution where less than 10 percent of the particles within the dispersion have a diameter twice that of the mean diameter of all particles within the dispersion.

Egon Matijevic - Potsdam NY
Wan P. Hsu - Potsdam NY
Manfred R. Kuehnle - New London NH
International Classification:
C08K 500
US Classification:
106499
Abstract:
A method of making synthetic color pigments comprises synthesizing monodispersed colloidal core particles by precipitation from a solution and applying dye material to the core particles either by adsorption directly into the core particles or by adsorption or incorporation into alumina fixation shells at the surfaces of the core particles. Additional functional shells may be applied to the dyed core particles for various reasons. The pigments are useful for the coloration of various media such as printing inks and paint compositions.
