A method for forming a protective antioxidative barrier on the furnace electrodes using a chemically altered cooling liquid containing an antioxidant additive. This method can be applied to electrodes used in electric arc furnaces and ladle metallurgy furnaces. The method can involve spraying the cooling liquid onto the electrode, thereby forming the protective antioxidative barrier and reducing the oxidation of the electrode.

The present invention relates to a low-temperature sinterable copper particle material prepared using an electride and an organic copper compound and a preparation method therefor and, more particularly, to a copper nanoparticle which can be useful as a conductive copper ink material thanks to its small size and high dispersibility, and a method for preparing the copper nanoparticle by reducing an organic copper compound with an electride as a reducing agent. The present invention provides copper nanoparticles which can be suitably used as a conductive copper nanoink material because the copper nanoparticles show the restrained oxidation of the copper, have an average particle diameter of around 5 nm to cause the depression of melting point, are of high dispersibility, and allow the removal of the electride in a simple ultrasonication process. The prepared copper nanoparticles can be useful as an oxidation preventing protector or conductive copper ink material which is small in particle size and high in dispersibility.
