Ultra-fine ceramic oxide powder method for producing the ultra-fine ceramic oxide powder ceramic paste produced using the ultra-fine ceramic oxide powder and method for producing the ceramic paste

摘要

The present invention includes the steps of preparing a solution or dispersion mixture to sufficiently dissolve or uniformly disperse the ceramic composition material in a solvent or dispersion medium containing ceramic constituent elements and; Preparing a mixed solution by reduction to cause the combustion reaction was added to an amount or more required Citric Acid - is the ceramic oxide and anionic constituents of the ceramic constituent elements in dissolved or dispersed in a solution or dispersion thereof; And evaporated the solvent or dispersion medium by heat-treating the mixture at 100-500 ℃ anionic and non-explosive oxidation of the ceramic constituting elements by the addition of citric acid with a reducing action combustion aid - are removed causing a reduced combustion reaction, this time generated by the heat of reaction through the step in which the ceramic oxide is formed without scattering the final particle size of 1㎛ or less by the production method of obtaining a grain size distribution uniform ultrafine ceramic oxide powder, ultrafine ceramic oxide powder and a method for producing such second relates to fine ceramic oxide powder and a method using the produced ultrafine ceramic oxide powder for producing a ceramic paste and a ceramic paste film formation is possible in this way, the cold produced by a, of the particles by a single step at a low temperature ceramic oxide minutes excellent reactivity the fine size while To be prepared, and it is capable to use the produced ceramic oxide powder to prepare a ceramic paste which can be formed a film with only a heat treatment at a low temperature effect.
