What is the difference between iron oxide black and carbon black?

 

　　Iron oxide black is also called ferric oxide, black iron oxide. Iron oxide black is a black crystal with magnetic properties, so it is also called magnetic iron oxide. Iron oxide black hardness, soluble in acid solution, insoluble in water, alkali solution and ethanol and other organic solvents. Is a commonly used magnetic material. Usually used as pigments and polishes, but also for the production of audio tape and telecommunications equipment, photographic equipment. It can also be used in seventh and top coats.

　　Carbon black is a completely different pigment. Carbon black, also known as carbon black, is an amorphous carbon. Texture light, loose, very fine, very large surface area. Made of natural gas is called "gas black", made of oil is called "lamp black", made of acetylene is called "acetylene black". In addition, there are "trough black", "furnace black". According to the properties of carbon black, there are "reinforced carbon black", "conductive carbon black", "wear-resisting carbon black" and so on. Can be used as a black dye, for the manufacture of Chinese ink, ink, paint, etc., also used as a reinforcing agent for rubber.

 

　　Therefore, the key words to distinguish between iron oxide black and carbon black are: iron oxide black is magnetic black iron oxide, carbon black is a soft texture, mainly used in ink and rubber pigments, rubber has a reinforcing effect. Does that make sense?
