一.Definition of Iron Oxide
Iron oxide pigment is an inorganic pigment with good dispersion, good light resistance and weather resistance, non-toxic. According to the morphology, iron oxide has ordinary iron oxide, ultrafine iron oxide, granular iron oxide. The main colors of iron oxide are: iron oxide red, iron oxide yellow, iron oxide black, iron oxide orange, iron oxide green, iron oxide brown, iron oxide blue.

二.Iron Oxide Production Process

Iron Oxide Production Process:
The first step of crystal seed preparation: add iron sheet, water and air to the nitric acid pool;
The second step by step oxidation: transfer the prepared crystal into the oxidation synthesis reactor, adjust the temperature and PH, add iron nitrate and iron sheet as neutralizing, and conduct one-step oxidation by steam
The third step is second-step oxidation: add iron sulfate, iron sheet and water on the basis of one-step oxidation, and conduct second-step oxidation through steam
The fourth step has been screened
Step 5 Wash water and base alkali
Step 6 Press filtration and precipitation
Step 7 Dryer
Step 8 Smash
Step 9 Packaging and storage

三.Iron oxide application scope
Iron oxide is widely used in paint, paint, building materials, ink, plastic, ceramics, paper, leather and other industries, with a broad market space.
