| titleOfInvention | Manufacturing Method of Copper Oxide for Printed Circuit Board |
| abstract | The method for manufacturing copper oxide for a printed circuit board according to the present invention is a method for manufacturing copper oxide (CuO) for a printed circuit board, which has 99% or more purity of copper (mole), ammonia water (NH 4 OH) 3 to 5 mole, And a dissolving step of preparing a solution in which the copper is dissolved by mixing and stirring the mixture so as to have a ratio of 1 to 3 mole of ammonium carbonate ((NH 4 ) 2 CO 3 ); A first filtering step performed after the dissolution step to remove insoluble components generated in the solution generated in the dissolution step; Adding copper ammonium to the solution filtered in the first filtering step to prepare copper carbonate by heating to 30 ° C. to 100 ° C. to remove ammonia by supplementing CO 2 components; A second filtering step performed after the copper carbonate manufacturing step to prepare copper carbonate in the form of a wet cake by separating the generated copper carbonate and the solution; And a copper oxide manufacturing step of manufacturing copper oxide (CuO) by heating the wet cake type copper carbonate to an electric furnace at 300 ° C. to 800 ° C. after the second filtering step. |
