  PRODUCT INTRODUCTION OF CRYSTALLINE BORON POWDER The crystal type of boron is mainly β-shaped, and the β-shaped and γ-shaped cubes are synthesized to form a fixed crystal structure. The color is usually taupe powder or brown particles with irregular shape. The company is specialized in the production of CRYSTALLINE boron source manufacturers, but also the invention of CRYSTALLINE boron production technology research and development units. The regular particle size of the CRYSTALLINE boron powder produced by our company is 15-60μm; The conventional grain size of CRYSTALLINE boron particles is 1-10mm (special grain size can be customized according to customer needs), generally divided into 2N, 3N, 4N, 5N, 6N five specifications according to the purity.

  AMORPHOUS BORON POWDER 3N...

  PRODUCTION OF AMORPHOUS BORON POWDER Currently, the amorphous boron powder widely used in the boron powder market is mainly crude boron with a high impurity content produced by the magnesian thermal reduction method. The magnesian thermal reduction method is simple, has a high yield, and relatively low cost. Because standards vary greatly across different fields, the definition of “amorphous boron powder” is not entirely consistent. Amorphous Non-crystalline Boron Based on the specific gravity of boron, it is divided into amorphous boron and crystalline boron. Amorphous boron has a specific gravity below 1.73 g/cm³. The widely used amorphous boron is formed by reduction at around 1000℃, of which 60% is α-rhombic crystalline boron,And 40% is amorphous boron, a mixture of crystalline and amorphous. Due to its small particle size and uniform distribution, amorphous boron has high activity.
