DESCRIPTION
The hardness of metallic silicon powder is very high. Hardness is the ability of a material to resist scratches and wear. The higher the hardness, the harder the material is to be scratched and worn. The hardness of silicon metal powder is very high, its Mohs hardness can reach 9.5, much higher than the hardness of ordinary metal materials. This means that metallic silicon powder is resistant to high wear and scratches.
The surface morphology of metallic silicon powder is very special. The surface of silicon metal powder is an oxide film composed of silicon oxide. The oxide film will form a kind of microstructure during the formation of the silicon metal surface, which makes the silicon metal surface harder and smoother, thus improving its wear resistance. In addition, silicon oxide can also form chemical bonds with other materials, forming a bond with other materials, thus enhancing the adhesion between silicon metal and other materials and improving its wear resistance.
The crystal structure of metallic silicon powder is also one of the important reasons for its high wear resistance. The crystalline structure of metallic silicon powder is polycrystalline, in which the silicon atoms are arranged very closely in the crystal, thus providing better hardness and strength. In addition, the crystalline structure of silicon metal powder can also form a hard skin on the surface of the material, thus enhancing its wear resistance.
