Ferric hydroxide plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are rich and diverse. The following are some upstream and downstream related products related to ferric hydroxide:

1. Upstream products:

(1) Iron salts: Iron salts, such as ferric sulfate and ferric chloride, are important raw materials for the production of ferric hydroxide. By adjusting the pH, iron salts can react under alkaline conditions to form iron hydroxide precipitates.

(2) alkali: sodium hydroxide, potassium hydroxide and other alkaline absorbents are used to adjust the pH value in the production process of ferric hydroxide and promote the hydrolysis and precipitation of iron salts.

2. Downstream products:

(1) Iron oxide red: Iron oxide red can be obtained after filtering, washing, drying and calcination of iron hydroxide, which is an important inorganic pigment and is widely used in coatings, Printing ink, plastics and building materials and other fields.

(2) magnetic materials: iron hydroxide can be used to prepare magnetic iron oxide, such as iron oxide, etc., these magnetic materials are widely used in the fields of electronics, information and magnetic recording.

(3) Water treatment agent: ferric hydroxide has good coagulation and sedimentation properties, and can be used as a water treatment agent for wastewater treatment to effectively remove suspended solids and colloidal substances in water.

In short, the upstream and downstream related products of ferric hydroxide are rich and diverse, and have a wide range of applications in the field of chemical production raw materials.
