Boron powder, boron carbide powder, ultrafine boron powder
Boron powder
product details
(1) Product features: high purity, even powder, good oxidation resistance and corrosion resistance in the air.
(2) Product application: (a) diamond containing boron, compared with ordinary diamond, diamond containing boron has the characteristics of strong oxidation resistance, good heat resistance, good chemical inertness, good compression resistance and excellent semiconductor performance. In particular, the electrical properties of boron bearing diamond are very good. In higher temperature and harsh environment, the boron content in boron bearing diamond crystal is generally very low, but the effect on improving and improving the properties of diamond crystal is significant. (b) Alloy additive, artificial diamond, wire drawing die or propellant, detonator, flux in military industry. Raw materials of other boron compounds, etc.
(3) Common particle size specification: 200 mesh, 300 mesh, 5 μ m 3 μ m or according to customer requirements.
(4) Chemical composition and physical index (as shown below)
