【発明の詳細な説明】
〔産業上の利用分野〕
本発明は例えば厚膜ハイブリッドＩＣ用導体ペーストに
用いられる銀合金微粉末の製造方法に関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for producing fine silver alloy powder used, for example, in a conductor paste for thick film hybrid ICs.
厚膜ハイブリッドＩＣ等に用いられる導体ペーストには
Ａｇ系の金属粉末が混合されている。しかしＡｇ単独の
粉末であるとＡｇ粉末のマイグレーションやハンダくわ
れ性等に問題があるのでＡｇとともにＰｄやｐｔが併用
されている。しかしながら上記問題をより完全に解消す
るにはＡ。Conductor paste used in thick film hybrid ICs and the like contains Ag-based metal powder mixed therein. However, if a powder of Ag alone is used, there are problems with migration of the Ag powder, solderability, etc., so Pd or pt is used in combination with Ag. However, to more completely solve the above problem, choose A.
粉末にＰｄやｐｔ等の粉末を単に混合するよりもＡｇと
Ｐｄやｐｔ等を合金化して該合金を粉末化した方がより
一層望ましいことである。It is much more desirable to alloy Ag with Pd, pt, etc. and turn the alloy into powder, rather than simply mixing powder with Pd, pt, etc.
従来、ＡＫ−Ｐｄ合金粉末を製造する方法としては、硝
酸銀−硝酸パラジウム混合溶液に炭酸ソ−ダを添加して
Ａｇ−Ｐｄ複合炭酸塩として沈澱させ、該Ａｇ−Ｐｄ複
合炭酸塩の沈澱物を水素により接触還元する方法、また
上記の炭酸ソーダに代えてカセイソーダを使用すること
により酸化銀と水酸化パラジウムとの混合沈澱物を生成
し、該混合沈澱物を水素中で８０−１８０℃の温度範囲
で加熱して接触還元する方法（特願昭５６−１０８８２
１号）が提供されている。Conventionally, as a method for producing AK-Pd alloy powder, sodium carbonate is added to a mixed solution of silver nitrate and palladium nitrate to precipitate an Ag-Pd composite carbonate, and the precipitate of the Ag-Pd composite carbonate is A mixed precipitate of silver oxide and palladium hydroxide is produced by a method of catalytic reduction with hydrogen, or by using caustic soda in place of the above-mentioned sodium carbonate, and the mixed precipitate is heated in hydrogen at a temperature of 80-180°C. Method of catalytic reduction by heating in a range (Patent application 1988-10882
No. 1) is provided.
しかしながら上記従来の方法では沈澱を水素中で加熱し
て接触還元させるために沈澱粒子が還元中に成長したり
凝集したりすることを防止することが出来ない。また組
成のコントロールを溶液の調整で行なうため目標組成の
ものを得ることも困難であり、条件により変化しやすい
、更に金属硝酸塩は金属単体（地金）に比して高価であ
る。金属地金を硝酸に溶解して金属硝酸塩を得れば金属
硝酸塩を購入するよりも安価になるが、Ａｄの場合は硝
酸銀に簡単に溶解するけれどもｐｔの場合は極めて溶解
しにくく、硝酸塩溶液を得るのが困難であると云う問題
点を有している。However, in the above-mentioned conventional method, since the precipitate is heated in hydrogen for catalytic reduction, it is not possible to prevent the precipitate particles from growing or agglomerating during the reduction. Furthermore, since the composition is controlled by adjusting the solution, it is difficult to obtain a target composition, and it is easy to change depending on the conditions.Furthermore, metal nitrates are more expensive than simple metals (base metals). Obtaining metal nitrate by dissolving metal base metal in nitric acid will be cheaper than purchasing metal nitrate, but while Ad easily dissolves in silver nitrate, PT is extremely difficult to dissolve, so it is difficult to use a nitrate solution. The problem is that it is difficult to obtain.

硝酸を使用することが望ましい。The acids used in step 2 can be of any type, including inorganic acids such as sulfuric acid, hydrochloric acid, and nitric acid, and organic acids such as acetic acid and oxalic acid, but they must dissolve quickly and include Na, CI, etc., which are harmful if mixed into the conductor paste. It is desirable to use nitric acid because it does not contain ions.
工程２において生成された溶液は塩基性溶液を添加する
ことによってｐＨを調節した上で還元剤を加えて該溶液
中の金属イオンを還元する（工程３）。The pH of the solution produced in step 2 is adjusted by adding a basic solution, and then a reducing agent is added to reduce the metal ions in the solution (step 3).
工程３において用いられる塩基性溶液はカセイソーダ、

That is, a mixed aqueous solution matching the composition of the master alloy is obtained. Pd, In, and Au, which alone are difficult to dissolve in acid, are contained in the alloy base material.
ｐｔが含まれていても、該合金中にあってはこれら難溶
