The elemental oxide of Iron
What is iron oxide?
Iron oxide, alias limonite, ochre, iron, red, pink, Venetian red (mainly iron oxide), iron trioxide, etc. The chemical formula Fe2O3, dissolved in hydrochloric acid, is a reddish-brown powder. Its red-brown powder is a kind of low pigment, industrial called iron oxide red, used in paint, ink, rubber, and other industries; it can be used as a catalyst, glass, gem, metal polishing agent, can be used as iron-making raw materials. Iron and Fe is a kind of chemical element, is a crystal, its chemical symbol is Fe, atomic number is 26; in the periodic table of chemical elements in the fourth period, group VIII represents iron group elements.
What is the difference between iron oxide and iron
It's the most commonly used metal. It is a transition metal, the second most abundant element in the Earth's crust. China was one of the first countries to discover and master iron-making technology. In 1973, an iron-blade bronze yue from the Shang Dynasty was unearthed in Hebei Province, China. It shows that more than 3,300 years ago, the Chinese people knew about Iron, were familiar with the forging properties of Iron, recognized the difference in nature between Iron and bronze, and cast Iron on the blade of copper weapons to strengthen the toughness of copper. Scientific identification proved that the sword was forged from a meteorite. The maturation of bronze smelting technology has gradually created conditions for developing iron smelting technology. Iron is also found in the human body. A component of hemoglobin that helps transport oxygen.
Wet preparation of iron oxide
A certain amount of 5% ferrous sulfate solution is quickly reacted with excessive sodium hydroxide solution (requiring excessive alkali 0.04 ~ 0.08g/ml) at room temperature into the air so that all the red-brown colloidal solution of iron hydroxide, as the deposit of iron oxide crystal nucleus. With the crystal nucleus as the carrier and ferrous sulfate as the medium, through the air, at 75 ~ 85℃, in the presence of metal iron, ferrous sulfate, and oxygen in the mood to generate iron oxide (namely Iron red) deposition on the crystal nucleus, sulfate in the solution and metal iron action to regenerate ferrous sulfate, ferrous sulfate is oxidized by air to Iron red continued deposit. This cycle continues until the process ends, and you get red iron oxide.
Price of iron oxides
Iron oxides particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Iron oxides. A large amount of large amount will be lower. The Price of iron oxides is on our company's official website.
