Iron oxide is a basic oxide. Iron oxide is a kind of inorganic substance chemical formula Fe2O3 and red or dark red amorphous powder. Relative density 5~5.25, melting point 1565℃ (simultaneous decomposition). Insoluble in water, hydrochloric acid, sulfuric acid, and slightly soluble in nitric acid. Covering and coloring power is very strong, with no oil or water permeability. Stable in the atmosphere and sunlight, resistant to dirty gas, high temperature, and alkali resistance. The appearance is red-brown powder, soluble in strong acid, medium strong acid; the red-brown powder is a low pigment, industrial called iron oxide red, used in paint, ink, rubber, and other industries, and can be used as a catalyst, glass, gems, metal polishing agent, can be used as iron making raw materials. Iron oxide is the main component of rust. The leading cause of rust is that iron metal reacts with water and oxygen in the environment in the presence of carbon impurities, and iron metal rusts. For paint, ink, rubber, and other industries, it can be used as a catalyst, glass, gem, and metal polishing agents, and it can be used as iron-making raw materials. The most important use of iron oxide is as a pigment. The color is divided into iron oxide red, iron oxide yellow, iron oxide black, iron oxide brown by iron oxide red, and iron oxide black (and iron oxide yellow) mixed; Iron oxide orange is a mixture of iron oxide red and iron oxide yellow; Iron oxide green is a mixture of blue phthalocyanine blue and iron oxide yellow.
