Title: Improvements in or relating to the manufacture of sintered copper bodies
Inventor: JACKSON KENNETH
IPC: C22C1/10
Filed: 1960-09-28
Abstract: A sintered copper body containing not more than 2% of a dispersed refractory oxide such as Al2O3,SiO2,MgO,BeO is formed by coprecipitating from a mixed solution of a soluble copper compound and a soluble compound of a metal which forms a refractory oxide, a mixture of copper oxide and refractory oxide and/or compounds which form the oxides on heating, heating to decompose said compounds and then heating the oxides in a reducing atmosphere to form a powder mixture of copper and the refractory oxide which is then pressed and sintered.  Aqueous solutions such as nitrate of copper and the refractory metal oxide are used and precipitation of hydroxide, carbonates, oxalates or decomposable basic salts is effected by the addition of aqueous solutions of alkali metal or ammonium hydroxides, carbonates, and oxalates or oxalic acid. Alternatively, precipitation is effected by boiling the mixed solution whereby a solution of ammonium carbonate and magnesium nitrate is boiled in a distillation apparatus, the distillate passing over copper foil with a counter-current stream of hydrogen to form copper ammonium carbonate which is returned to the boiler and mixed with the magnesium nitrate to precipitate copper oxide and magnesium carbonate.  The precipitate formed is dried, heated in air below 900 DEG  C., crushed to minus 200 mesh, reduced in hydrogen at 300 DEG  C., compacted at 10-50 t.s.i. and then sintered at 850-1050 DEG  C. in vacuum, hydrogen, argon or nitrogen.  The sintered body is cold rolled, annealed and drawn to form wire. Specification 919,052 is referred to.
