    Product Description

    Cobalt tetroxide powder is a black powder, insoluble in water, with metallic luster and good electrical conductivity. Cobalt tetroxide is highly oxidizing and can release oxygen in an acidic environment. Cobalt tetroxide powder is an important catalyst, which can be used to synthesize ammonia, formaldehyde, oxalic acid and other organic compounds. It is also a high-performance magnetic material and pigment. In battery manufacturing, it is often used as a positive electrode material, which can effectively reduce the internal resistance of the battery. In addition, it can be used as a precursor for lubricants and high-temperature superconducting materials.

    Quality control system

    quality control

    Huarui has strict quality management system. We test our products first after we finish our production, and we test again before every delivery, even sample. And if you need, we would like to accept third party to test. Of course if you like, we could provide sample to you to test.

    Our product quality is guaranteed by Sichuan Metallurgical Institute and Guangzhou Institute of Metal Research. The long term cooperation with them can save a lot of testing time for customers.
