Is iron oxide rust?

Iron oxide, also known as iron oxide, burnt limonite, burnt ochre, iron red, iron red, red powder, Venice red (the main component is iron oxide), etc. Chemical formula fe2o3, soluble in hydrochloric acid, is reddish brown powder.

What color is rust?
Rust is a reddish-brown substance. It is not as hard as iron and can easily fall off. After a piece of iron is completely rusted, its volume can expand 8 times. If the rust is not removed, this spongy rust is particularly easy to absorb water, and the iron will rot faster.

How to remove rust
To remove rust, you can use various tools to shovel it away, or soak it in an acidic solution to dissolve it. After removing the rust, be sure to treat the surface of the ironware, apply a layer of lead red, and then paint; or plate other metals that are not easy to rust. A more thorough method is to add some other metals to iron to make a stainless alloy. The stainless steel we are familiar with is an alloy made by adding a little nickel and chromium to steel.

Application industries of iron oxide
Its reddish brown powder is a low-grade pigment, industrially called iron oxide red, used in paint, ink, rubber and other industries, can be used as a catalyst, a polishing agent for glass, gems, and metals, and can be used as a raw material for ironmaking.
What is the difference between the blue phase and the red phase of iron oxide black?
The blackness of the blue phase iron oxide black is significantly higher than that of the red phase iron oxide black, and the blue phase iron oxide black contains less impurities and has a strong hiding power.

Product performance
Iron oxide black is a blue black powder with a visual blackness similar to carbon black. It has a fine texture and is insoluble in water and alcohol, but soluble in concentrated acid and hot acid. It is magnetic and has high tinting power and hiding power. It has good weather resistance, light resistance, atmospheric resistance, durability, no water permeability and oil permeability. It is stable in general organic solvents, has good alkali resistance, and heats up to 180°C. It is easy to be oxidized when heated at high temperature, turning into red iron oxide. When burned at 200~300℃, γ-type iron trioxide is formed. It can cooperate with other subtle colors to form a light radiation effect, showing translucency.

Product Usage
S353 iron oxide black is mainly used in the building materials industry for colored cement, colored cement floor tiles, colored cement tiles, imitation glazed tiles, concrete floor tiles, colored mortar, colored asphalt, terrazzo, mosaic tiles, artificial marble and wall painting, etc.; in paint and paint Mainly used in the industry to manufacture various paints, coatings, and inks. In other industries, such as ceramics, rubber, plastics, leather polishing paste, etc. are used as colorants and fillers.
