Counterflow diffusion flame synthesis of ceramic oxide powders

Katz, Joseph L; Miquel, Philippe F

Title: Counterflow diffusion flame synthesis of ceramic oxide powders

Abstract

Ceramic oxide powders and methods for their preparation are revealed. Ceramic oxide powders are obtained using a flame process whereby one or more precursors of ceramic oxides are introduced into a counterflow diffusion flame burner wherein the precursors are converted into ceramic oxide powders. The nature of the ceramic oxide powder produced is determined by process conditions. The morphology, particle size, and crystalline form of the ceramic oxide powders may be varied by the temperature of the flame, the precursor concentration ratio, the gas stream and the gas velocity.

Molecular decomposition process for the synthesis of nanosize ceramic and metallic powders

Patent Virkar, Anil Vasudeo; Bhide, Sanjeevani Vidyadhar

A process is disclosed for forming a nanosize ceramic powder. A precursor ceramic material is formed of a fugitive constituent and a non-soluble constituent in a single phase. The precursor is contacted with a selective solvent (water, acid, etc.) to form a solution of the fugitive constituent in the solvent and a residue of the non-soluble constituent. The precursor is sufficiently reactive with the solvent to form the solution of the fugitive constituent in the solvent and form the nondissolved residue of the non-soluble constituent. The precursor material and the non-soluble residue are sufficiently insoluble in the solvent such thatmore » « less

Method of making metal oxide ceramic powders by using a combustible amino acid compound

Patent Pederson, Larry R [Kennewick, WA]; Chick, Lawrence A [Richland, WA]; Exarhos, Gregory J [Richland, WA]

This invention is directed to the formation of homogeneous, aqueous precursor mixtures of at least one substantially soluble metal salt and a substantially soluble, combustible co-reactant compound, typically an amino acid. This produces, upon evaporation, a substantially homogeneous intermediate material having a total solids level which would support combustion. The homogeneous intermediate material essentially comprises highly dispersed or solvated metal constituents and the co-reactant compound. The intermediate material is quite flammable. A metal oxide powder results on ignition of the intermediate product which combusts same to produce the product powder.

Nonaqueous solution synthesis process for preparing oxide powders of lead zirconate titanate and related materials

Patent Voigt, James A [Corrales, NM]; Sipola, Diana L [Albuquerque, NM]; Tuttle, Bruce A [Albuquerque, NM]; ...

A process for producing powders of perovskite-type compounds which comprises mixing a metal alkoxide solution with a lead acetate solution to form a homogeneous, clear metal solution, adding an oxalic acid/n-propanol solution to this metal solution to form an easily filterable, free-flowing precursor powder and then calcining this powder. This process provides fine perovskite-phase powders with ferroelectric properties which are particularly useful in a variety of electronic applications.
