What is Fe carbonate？

Ironcarbonate is the main component of siderite. White triangular crystal, easily oxidized to yellow powder when exposed to water and oxygen. Density 3.8g/cm3. Insoluble in water. It starts to decompose into carbon dioxide and ferrous oxide when heated to 282°C in isolation from air, and decomposes into carbon dioxide and iron oxide (positive trivalent) when heated in air. Soluble in acid and carbon dioxide solutions. Its dry product is stable in air. The wet product is oxidized into iron hydroxide in the air and turns into brown color. In addition, ferrous carbonate is often produced by the interaction of alkali metal carbonate and ferrous salt solution. It can be used to make iron salts, veterinary drugs, blood tonics mixed with sugar, and can also be used as negative electrode materials for lithium-ion batteries..

应用

1. Steel smelting

Ferrous carbonate is widely used in the steel industry. It is an important type of iron ore that reacts with coke at high temperatures,

Generate carbon dioxide and iron. This reaction is used to produce high-purity iron for the manufacture of steel and other iron products

Product. Ferrous carbonate can also serve as a reducing agent in the smelting process, helping to remove impurities.

2. Chemical reagents

Ferrous carbonate, as an important chemical reagent, has a wide range of applications in the laboratory and industry. It can

Used for preparing other iron compounds, such as ferrous oxide, ferrous hydroxide, etc. Ferrous carbonate can also be used as a dye

The raw materials for pigments, such as reddish brown ochre pigment, are made from ferrous carbonate.

3. Water treatment

Ferrous carbonate can be used as a water treatment agent to remove oxygen and sulfides from water. Carbonate placed in water

Iron reacts with oxygen to form ferrous oxide, which is then precipitated. This reaction can reduce the oxygen content in water,

Reduce corrosion and oxidation reactions. In addition, ferrous carbonate can also react with sulfides in water to form precipitates

Effectively remove sulfide pollution.

4. Soil amendment

Ferrous carbonate has certain applications in agriculture. Adding an appropriate amount of ferrous carbonate to soil can improve soil compaction

Structure and texture, and provide the iron element required for plant growth. The effect of ferrous carbonate on soil acidity, alkalinity, and conductivity

It has a regulating effect and helps to improve soil fertility and crop yield.

5. Preservatives

Ferrous carbonate has certain applications in wood preservation. Immersing ferrous carbonate solution into wood can reduce

The degree of bacterial and insect erosion on wood prolongs its service life.
