Amorphous Boron Powder, boron nitride, boron Molecular formula:B Moleular weight:*0.*1(International Atomic Weight ***9) Quatily standard:Company standrad(QJ/YH*2·****9) Content:B(%)≥*0 B(%)≥*2 Features: This product is a amorphous boron, brown to grey/black powder. Boron is at the specific position on periodic chart, which is a border between the metal and non-metal. It feautures more negative. little diameter of atom, -nuclear-charge concentrated the property of non-metal similar to silicon. In air, it can combust at ***0C, . and can not react with all metal, metal oxide and non-metal oxide at less ***0C Specific weight: 2.***2.*5. Boron and non-oxygen *****, etc. are stable at the boiling temperature. No effect in stro- ng base and melting NaoH.at ***0C., Applications: 1It can be used as protective material and boron steel for atomic reactor in atomic energy industry. 2In smelting industry. since boron and metal can be formed metal-boroide with high melting point, so when inletting the paryicular quantity boron into the most of alloys, it is possible to change well the physical-mechanical features of the alleys, and ake the place of or save a quantity of precious and th- in metals. 3In semiccrdaotor and elecnorjcs, after carbonated at about ****0C, can be used as cathode the materal of ignitioncores in ignition pipe, also can be as the material making the branded cathode material, lanthanum boride. 4In chemical industry, this is a important material making hing pure boron halide.
