Ferrosilicon (FeSi) is an alloy of iron and silicon with a very variable silicon content between 10% and 90%. It is used as a so-called master alloy in steel production, which is added in small amounts in order to adjust the properties of the melt, the cooling process and the finished product.
The main advantage of FeSi is its deoxidizing effect (i. e. it reduces metals from their oxides), but it also helps to prevent the loss of carbon. Furthermore, ferrosilicon is used in electrode coatings and in the production of silicon, hydrogen and magnesium.
Ferrosilicon is produced either in a blast furnace or electric arc furnace by the reduction of quartz sand (SiO2) with coke in the presence of iron. The melt is poured out of the furnace and solidifies in the form of a flat sheet.
After cooling, this sheet is crushed by appropriate machinery and then further processed in a crusher. The resulting particle size distribution ranges from fine dust-like particles to cm-sized chunks. The FeSi is sifted into different size grades for further use.
Microtrac's CAMSIZER series is ideally suited for the particle size distribution analysis of ferrosilicon and other granular metals. Microtrac analyzers are used both for quality control industrial applications as well as research purposes.

What is inoculant and do you need it?

Inoculant is Rhizobium bacteria that is applied to legume seed (clovers, cowpeas, etc.) before planting. The nodules on the roots of legumes contain Rhizobium bacteria, which are responsible for fixing nitrogen for the plant. Applying inoculant to the seed ensures that the correct type of bacteria specific to that legume are available to the plant once it germinates.

Rhizobium bacteria is found in many soils, but planting legumes that have not been inoculated is taking a chance as to whether or not the specific strain of bacteria required for that legume is already present in the soil. In many cases, once a successful crop of a specific legume is grown in a field, there will be sufficient quantities of Rhizobium remaining in the soil to accommodate another planting of the same legume. But, many factors, such as cultural practices, weather conditions and soil conditions, may affect the survivability of the carry-over Rhizobium in the soil. In short, many people grow successful stands of legumes from seed that was not inoculated.
