how is boron carbide made?
I think there are two different polymorphs with drastically different applications. They are probably synethsized accordingly, but pretty sure they start with a boron rod, plunge into carbon then pump lots of current through it
. I'll ask some friends as they are using it as heat resistant coatings for the missle noses and engine cones, they'll know exactly if you want more specific.
here is a link I found
Potassium is much more interesting than carbide. Don't waste your time studying petty elements. Go with Potassium!
