Iron oxide is also known as burnt limonite, burnt ochre, iron pill, iron red, red powder, etc. The appearance is reddish brown powder, which is easily soluble in strong acid and medium strong acid. Its reddish brown powder is a low-grade pigment, which is called iron oxide red in industry. It is used in paint, ink, rubber and other industries. It can be used as catalyst, polishing agent of glass, gem and metal, and can be used as raw material for ironmaking.

It is used for high-grade fine grinding materials and polishing precision hardware instruments, optical glass, etc. High purity is the main base material of powder metallurgy, which is used to smelt various magnetic alloys and other high-grade alloy steels. It is obtained by calcining ferrous sulfate or iron oxide yellow or lower foot iron at high temperature, or directly from liquid medium.

Purpose: 1. In the building materials industry, it is mainly used for color cement, color cement floor tiles, color cement tiles, imitation glazed tiles, concrete floor tiles, color mortar, color asphalt, terrazzo, mosaic tiles, artificial marble and wall painting; 2. Used for coloring and protecting various coatings, including water-based interior and exterior wall coatings, powder coatings, etc; It can also be applied to oily paints, including epoxy, alkyd, amino and other primers and topcoats; It can also be used for toy paint, decorative paint, furniture paint, electrophoretic paint and enamel paint. Iron red primer has anti rust function, which can replace high priced red lead paint and save non-ferrous metals. 3. Used for coloring plastic products, such as thermosetting plastics and thermoplastics, and coloring rubber products, such as automobile inner tube, aircraft inner tube, bicycle inner tube, etc.
