Iron Powder, 200grams
Price:
$39.95
Chemical Name:
Iron Powder
CAS Number:
7439-89-6
Chemical Formula:
Fe

Detailed Product Description:

A finely ground silver/gray powder. Iron is highly reactive

chemicallya strong reducing agent. Oxidizes readily in moist

air. Reacts with steam to yield hydrogen and iron oxides.

Dissolves in no-oxidizing acids (sulfuric and hydrochloric

acids) and in cold dilute nitric acid.

Grade/Purity:

This is Reagent Grade material with a minimum purity of 99.5%.

Applications:

Iron powder is typically used in powder metallurgy or for class-

room demonstrations of magnetism.

Background:

Iron is a lustrous, silvery soft metal. It is one of the few ferromagnetic

elements. Iron, along with nickel, are the most abundant metals in

metallic meteorites and in the dense-metal cores of planets such as Earth.

Iron and iron alloys are also the most common source of ferromagnetic

materials in everyday use.

Allotropes:

Iron represents perhaps the best-known example of allotropy in a metal.

There are four allotropic forms of iron, known as alpha, beta, gamma,

and delta.

As molten iron cools down it crystallizes at 1535C into its delta allotrope,

which has a body-centered-cubic (BCC) crystal structure. As it cools

further its crystal structure changes to face-centered-cubic (FCC) at

1401C, where it is referred to as gamma-iron, or austenite. At 912C

the crystal structure again becomes BCC as beta-iron is formed, and

at 770C (the Curie point, Tc) the iron becomes magnetic as alpha-iron,

also known as ferrite, which is also BCC.

Alpha iron, also known as ferrite, is the most stable form of iron at

normal temperatures. It is a fairly soft metal that can dissolve only a

small concentration of carbon (no more than 0.021% by mass at 910 C).

Above 912C and up to 1401C alpha iron undergoes a phase transition

from body-centered-cubic to the face-centered-cubic configuration of

gamma iron, also called austenite. This is similarly soft and metallic

but can dissolve considerably more carbon (as much as 2.04% by

mass at 1146C). This form of iron is used in the 300 series (Austenitic)

stainless steels, often used for making flat ware, and hospital and food-service

equipment.
