    Product Description

    Chromium diboride is insoluble in water but soluble in molten sodium peroxide. High hardness, good wear resistance, high temperature oxidation resistance below 1300 ℃, corrosion resistance, thermal shock resistance. Because of its good chemical inertness and the characteristics that it is not easy to bond with metals, it can meet special chip processing requirements as a hard protective coating.


    Chromium Boride Powder Composition (%)
















    Chromium boride can be used as wear-resistant, high-temperature oxidation resistant coatings and neutron absorption coatings in nuclear reactors. It can be used in ceramics and melt-blown on the surface of metals and ceramics to form wear-resistant and corrosion-resistant films. It can also be used to spray semiconductor films. Chromium boride and alumina are sintered or hot-pressed products in a slightly oxidizing atmosphere, which has the practical value of high temperature wear resistance.

    1. Materials for producing composite ceramics

    2. It can be used as neutron absorber

    3. Wear resistant coating; crucible lining and corrosion-resistant chemical equipment

    4. Composite materials with oxidation resistance

    5. Refractory, especially in the case of corrosion resistance of molten metal; heat strengthening additive

    6. High temperature and corrosion resistance coating

    7. Anti-oxidation special coating.

    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.
