preparation example Construction

[0041] The preparation of the mixture can be performed at room temperature, but is not limited thereto.

[0042] In addition, 12-200 parts by weight of urea (CO(NH 2 ) 2 ) is mixed with the aqueous solution to complete the preparation of the mixture.

[0043] The urea (CO(NH 2 ) 2 ) is mixed with the aqueous solution to prepare the mixture, so that the copper precursor can be prepared in a large amount at a relatively low temperature.

[0044] Based on the hydrate of the copper salt or copper salt of 100 parts by weight, in urea (CO(NH 2 ) 2 When the content of ) is less than 12 parts by weight, the content of urea is obviously too low, therefore, the copper precursor cannot be synthesized sufficiently.

[0045] Simultaneously, with the described copper salt of 100 weight parts or the hydrate of copper salt as benchmark, in urea (CO (NH 2 ) 2 ) content is more than 200 parts by weight, the content of urea is obviously too high, therefore, the copper precursor cannot be...

Embodiment

[0073] At room temperature, 1-16kg copper nitrate, copper nitrate trihydrate (Cu(NO 3 ) 2 ·3H 2 O) dissolved in water to obtain an aqueous solution.

[0074] Next, at room temperature, 2-10kg of urea (CO(NH 2 ) 2 ) with dissolved copper nitrate trihydrate (Cu(NO 3 ) 2 ·3H 2 O) aqueous solution mixed.

[0075] The mixed solution is heated to 100-120 °C to synthesize the copper precursor Cu 2 (NO 3 )(OH) 3 .

Abstract

There is provided a method of producing a copper precursor and a copper precursor produced by using the same. The method of producing a copper precursor includes: preparing an aqueous solution including a copper salt or a hydrate thereof; preparing a mixture by mixing urea (CO(NH2)2) with the aqueous solution; and synthesizing the copper precursor by heating the mixture at a temperature of 100 to 120° C.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0041519 filed with the Korean Intellectual Property Office on Apr. 20, 2012, the entire contents of which are hereby incorporated by reference into this application. technical field [0003] The present invention relates to a copper precursor (copper precursor) and its preparation method, and more specifically, to a copper precursor preparation method and the copper precursor prepared by this method. The method does not need to generate intermediate Copper precursors can be prepared from intermediates, and copper precursors can be synthesized at low temperatures. Background technique [0004] Since copper (Cu) has the same level of specific resistance as silver (Ag), and has a low cost of about one percent of silver (Ag), it is currently used as wires for most electronic components. [0005] Copper (Cu) is mostly used in the form of powder in ...
