(alumino-magnesiothermic) reduction of boron oxide (B 2 O 3) production methods were investigated. The impact of varying the reductant mass was investigated. The alloys produced by the aluminothermic, magnesiothermic and alumino-magnesiothermic production methods were analyzed in comparison to NiB master alloy B specification.

various low carbon ferro-alloys such as ferro-manganese, ferro-chrome, ferro-vanadium ferro-titanium, ferro-boron, ferro-silico zirco-nium and ferro-tungsten, con-taining trace to 0.1% carbon can be produced. The compositions for these low carbon ferro-alloys are mentioned in Table I and Figure 3 illustrates various steps of their production.

PRODUCTION OF FERRO BORON. A large portion of the global Ferro Boron supply is manufactured in China, India and Turkey. The most basic definition of the Ferro Boron production process would be that a small amount of raw Boron is added to iron to create a ferrous alloy, although the actual methods used are somewhat more complicated.

Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese (Mn), aluminium (Al), or silicon (Si). They are used in the production of steels and alloys. The alloys impart distinctive qualities to steel and cast iron or serve important functions during production and are, therefore, closely associated with the iron and steel industry, the ...
