Ferroboron

Ferroboron (FeB) is a ferroalloy consisting of iron and boron. The metal usually contains 17.5% to 20% boron and is used to produce boron steels.

This article is about the ferroalloy. For specific borides of iron, see Iron boride.

Description

Ferroboron is (CAS Registry Number 11108–67-1) is a ferroalloy of iron and boron with boron content between 17.5 and 20%.[1]

It is manufactured either by carbothermic reduction of boric acid in an electric arc furnace together with carbon steel, or by the aluminothermic reduction of boric acid in the presence of iron.[1]

Ferroboron is added to C-Mn and other low alloy steels to improve hardenability (see Boron steel), and can also act as a nitrogen scavenger in steel, and in the production of NdFeB magnets.[1]

gollark: Maybe we could replace the people in the miniature universe with slightly smarter people, and give them better pens.
gollark: Sensors and propulsion are pretty useful, as we're meant to be surveying stuff and whatnot. Mining and power are important for infrastructure, I guess. Computing isn't too much of a problem as the magic computer box™ is only 10 minerals.
gollark: We don't really need weapons much, so that just leaves... everything else.
gollark: Anyway, can we get the research forks to focus on specific areas?
gollark: It's fine, we're probably overthinking this a lot...
