Prevention oxidation of Cu powders

I read here that there is an option of preventing oxidation of Cu powders with tarnish solution.
which kind of solution should we use? where can we get it?

Benzotriazole ⇦ on eBay or Amazon [affil links] is an excellent temporary tarnish preventer for copper. I probably needn't warn a specialist like yourself, but for the benefit of readers, the speed of reaction of processes is orders of magnitude faster when working with powder because of the enormous surface area. Never try reacting powdered metals unless you know exactly what you are doing because fire or explosion are possibilities.

How can we use benzotriazole to prevent surface oxidation of reduce copper powders? How it should be mixed etc.
