Thermite Fe3O4

This is a 50g total sample test at 3:1 ratio, I have a further 2kg which I will burn at 3.22:1 and post at some point, probably in one lot.

Well, it is iron, so we could try and figure out a way to oxidize it. You could try scraping it off to get it unstuck to the concrete, but you have probably already tried this. Or you could try electrolysis on it, but you would somehow need to get it under saltwater and have an electric current going for weeks. You could get it red hot and blow pure oxygen over it, that would do it for sure. But no matter what the burn mark will still be there. And some of the debris could be cracked concrete.

Sorry, I didn't make myself clear. The spatter cracks off easily, albeit with pieces of my yard attached to it. I was referring to reducing the amount of spatter as you seemed to allude to it being abnormal. I presumed the spatter is not normally this violent. Is that correct?

LOL at saltwater technique, I think I'll stick to the chipping hammer!

Yes, but that is only because you used Fe3O4 instead of Fe2O3. For your type of thermite it was normal, you can use Fe2O3 to reduce the spatter. Or if you want to have a ton of fun and increase the spatter, get a thirty foot magnesium ribbon and copper oxide. This mixture is explosive, makes a loud boom, and shoots blobs of molten copper everywhere. This or you could make some type of shield and do it over a snowy field like I did.

I only bought the Fe3O4 because I reasd the reaction was more exothermic so I guess I wanted the spatter really. The Copper mix sounds easy and fun, I'll have to find somewhere in the UK to get it. Cheers very much for the idea.

Wow, that's some fun splatter to have land on you

[chunkyfecalbreakfast]

Yeah, there are melted chunks out of

the concrete slabs all over the yard now.  Any tips on reducing that?

[ExplosiveScience]

Yeah, I assumed you knew that Fe3O4 was more exothermic, but be careful with that copper thermite, I would start with less than twenty grams and work your way up. Obviously don't do it anywhere flammable and I would recommend watching a few videos about it before using it. Anyways, good luck with the plans, and I will be sure to watch your future videos especially on this topic.

37.5g Fe3O4 to 12.5g Al, it was just a rough mix as I couldn't remember the right ratio.

How much ironoxide an how much aluminium du you used ?
