    Product Description

    Crystal boron powder is an inorganic substance composed of boron, its molecular formula is B2O3. The physical properties of crystalline boron powder mainly include its white powdery appearance, high density and low electrical conductivity. This material has good stability to heat and chemicals, and its high density makes it widely used in glass and ceramic manufacturing. Chemically, crystalline boron powder shows a strong reaction to acids, especially with strong bases such as sodium hydroxide. It can form various boric acids, which is its importance in chemistry and materials science. The main use of crystalline boron powder is as an additive to glass and ceramics to increase their hardness and strength. It can also be used in the production of borax and other borates, which have applications in glass, ceramics, detergents and cosmetics.

    Crystalline boron powder is mainly used in alloy additives, synthetic diamond, wire drawing dies, other boron compounds raw materials or propellants, detonators, fluxes in the military industry, etc.

    1. 2N crystalline boron powder is generally used in boron-copper alloy, ferroboron alloy, boron-aluminum alloy, boron-nickel alloy, etc.

    2. 3N, 4N crystalline boron powder is mostly used in lithium-boron alloys.

    3. 3N, 4N crystalline boron powder can be made into amorphous boron powder

    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.
