Description
Amorphous Boron Powder, boron nitride, boron
Molecular formula:B
Moleular weight:10.81(International Atomic Weight 1979)
Quatily standard:Company standrad(QJ/YH02·07-89)
Content:B(%)≥90 B(%)≥92
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 7000C, . and can not react with all metal, metal oxide and non-metal oxide at less 7000C Specific weight: 2.33-2.45.
Boron and non-oxygen *****, etc. are stable at the boiling temperature. No effect in stro-
ng base and melting NaoH.at 5000C.,
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 23000C, 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.
