Black Iron Oxide For Building Materials
Property:
Iron oxide black has excellent physical and chemical properties. Strong hiding power, high tinting power, soft color, stable performance, and non-toxic. It is a green and environmentally friendly pigment; alkali resistant, stable to weak and dilute acids, excellent light resistance and heat resistance, soluble in water , Has excellent anti-rust and anti-ultraviolet effects. Mainly used in colored cement parts, plastics, rubber, ceramics, paint, building materials, etc.
The full name of iron black is iron oxide black, which is a black inorganic pigment with ferroferric oxide as the main component, and its chemical formula is Fe3O4 or Fe2O3·FeO. The appearance is black powder, the refractive index is 2.42, the particles are cubic, the coloring power and hiding power are high, ACID, alkali, light and easy to disperse, heat-resistant to 100 ℃, burned at 200 ~ 300 ℃ to form γ-trioxide Second iron, high temperature oxidation to red α-iron trioxide. Iron oxide black can be prepared with ferrous solution, alkali and oxygen (ferrous oxidation method), or ferrous sulfate can be made from iron filings and sulfuric acid, and then made into ferrous hydroxide with Caustic Soda at a certain temperature and pH It is formed by adduct with ferric oxide, and can also be prepared by aniline method. It is mainly used for the coloring of paints, inks, and building materials, and can also be used in the electronics and telecommunications industries.

Iron oxide is an inorganic substance with the chemical formula Fe2O3. Red or dark red amorphous powder. The relative density is 5~5.25, and the melting point is 1565°C (decompose at the same time). Insoluble in water, soluble in hydrochloric acid and sulfuric acid, slightly soluble in nitric acid. It has strong hiding power and tinting power, no oil permeability and water permeability. It is stable in the atmosphere and sunlight, resistant to polluted gases, high temperature and alkali. The dry-process products of this product have coarse and hard crystal particles, which are suitable for magnetic materials, polishing and Abrasive materials. Wet-processed products have small and soft crystal particles, suitable for coating and ink industry.
