Iron can be alloyed with chromium to make stainless steel, which does not rust under most conditions. Iron powder can react with sulfur to make iron(II) sulfide, a hard black solid. Iron also reacts with the halogens to make iron(III) halides, like iron(III) chloride. Iron reacts with the hydrohalic acids to make iron(II) halides like iron(II ...

PRODUCTION OF IRON AND STEEL POWDERS This chapter presents a short history of iron powder and a brief account of how world production and consumption of iron powder have developed since 1965. It describes in detail two production methods which together account for more than 90% of today's world production of iron and steel powders.

Thermite (/ ˈ θ ɜːr m aɪ t /) is a pyrotechnic composition of metal powder, which serves as fuel, and metal oxide.When ignited by heat, thermite undergoes an exothermic reduction-oxidation (redox) reaction. Most varieties are not explosive, but can create brief bursts of heat and high temperature in a small area.

Powder metallurgy is also known as press-and-sinter. Many metals are treated with this process to produce a porous material called sponge fines. For example, iron sponge fines are small particles of iron ore that have been reduced by heat. Sponge iron can come in lumps or finer particles and is frequently used as an alternative to steel scrap ...

Gunpowder, also known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive.It consists of a mixture of sulfur (S), charcoal (C), and potassium nitrate (saltpeter, KNO 3).The sulfur and charcoal act as fuels while the saltpeter is an oxidizer. Because of its incendiary properties and the amount of heat and gas volume that it generates ...

This has been for long the most widely used method for the production of iron powder. Selected ore is crushed, mixed with carbon, and passed through a continuous furnace where reaction takes place leaving a cake of sponge iron which is then further treated by crushing, separation of non-metallic material, and sieving to produce powder.
