: EXTERNAL: Re: [Vo]:Removing nickel oxide layer A glovebox filled with inert gas would help, I agree, but most of the Ni Powder is shipped in non cealed jars or even envelopes so they are already oxidized at arrival. I also read that CO gas would help removing Ni oxide, perhaps at lower

That confirms it indeed, I wasn't aware Ni powder already sinters at around 300C. Good to know. I wonder whether silica would do the job to prevent sintering of Ni (powder or layered on top) Recently I read Celani's patent application WO2011016014, where nickel powder is oxidized and then a silica

Nickel oxide is removed pretty easily in H2 at about 310C. Once it is removed, you will see the sintering begin at the same temperature. The clean Ni surfaces begin to bond and the particles begin to grow. That is why, in part you must add the catalyst powder - to prevent the wholesale sintering

Just buying nickel micro powder, I assume this comes slightly oxidized. How would that be removed as a first step in preparing nickel powder for LENR experiments? Just heat in in a hydrogen environment at temperatures of a few hundred degrees C?
