Ferroboron (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.

The introduction of boron steel elements introduced issues for accident scene rescuers as its high strength and hardness resisted many conventional cutting tools (hydraulic rescue tools) in use at that time. [3] [4] Flat boron steel for automotive use is hot stamped in cooled molds from the austentic state (obtained by heating to 900-950 °C ...
Iron borides can be formed by thermochemically reacting boron rich compounds on an iron surface to form a mixture of iron borides, in a process known as boriding.There are a number of ways of forming boride coatings, including gas boriding, molten salt boriding, and pack boriding. [6]
The same principle applies when baking soda is used to boil pretzels before baking. The pantry staple can also serve as a tenderizer for certain ingredients—like meat and even canned chickpeas .
Laterite ores are often used to supply the production process. [13] [14] The RKEF process is often used. [15] The energy consumption per tonne of product is high for laterite ores because of the low-grade feed, and hence produces a lot of waste slag and gaseous pollution. [16] Generally, over 90% of the furnace output is in the form of slag. [8]
