Boron is a ordinary non-metallic element, has a variety of allotropes: tetragonal crystal, rhomb, diamond thing and nebulous shape.
Knowledge and application of boron
Amorphous boron powder is a kindly of powder that the color from dark brown to dark Crystal boron is laborious andbrittle insoluble with sinisteru to silver metallic luster Boron conductivity was increasingwith the temperature increased. Borons chemical property depends on itsphysical state, dim boron can slowly oxidize in the music even at roomtemperature, and the crystal boron is stable even heated, only can slowly reactwith strong oxidant Amorphous boron powder at tall temperatures can burn inthe air, effect red flame; also can operate with halogens, nitrogen and metals,forming boron halides, boron nitride and metal boride, but does not directlyinteract with the hydrogen
Boron oreis a widely used chemical mineral, can fire with the compounds of hydrogen,lithium, beryllium and so on, is a genial of high-energy jet fuel Boron andboron compounds are widely used in chemical industry, metallurgy, optical glass,defense, nuclear, pharmaceutical, rubber and light industry In the chemicalindustry, borax, boric tart can be used as soaps, detergents and otherhousehold chemical products, additives. Boron-containing abstergent has hair-protection,strong detergency, no pollution and further properties. Certain borides can alsobe made of advantage reducing agents, catalysts, bromide, etc
In themetallurgical industry, borax has the facility to melt metal oxides, used for ametallurgical flux Colemanite can be instead of fluorite used in alkaline oxidationconverter steelmaking. Copper assortment with traces boron can increase itsconductivity Boron at colossal temperatures can act with the oxygen and nitrogen,commonly used for degassing agent Plus 0.001-0005% boron to the steel canimprove the tall temperature strength, improve the steel grain, improvedhardenability After steel surfaces boronizing, can significantly increase thesurface hardness, moreover improve the chemical stability 0001-0.003% boron addedto the malleable iron, can reduce the treatment time, correct the graphite,distributed evenly. In the gadgetry industry, boron is used in grinding,drilling and polishing arduous metal, precious stones and further hard materials”Boronizing” is a new process in specialized processing industry, itcan improve parts surface hardness and wear resistance, oxidation resistance
In theelectronics industry, some of boride compounds in boron series are insulatingmaterials, and some borides are profit conductive materials, having the propertiesof semiconductors, and electron emission properties, can be used to manufacturevarious electronic element, device, used as the ignition drainpipe of ignitionelectrode, telecommunications equipment, capacitors, semiconductors admixtures,high frequency electric and plasma arc insulator, radar articulation window, etc.
In thedefense industry, boron compounds can be used as high-energy jet fuel androcket fuel Boron carbide used for manufacturing jet blades and cermet Boronnitride is a ultra-high temperature, super-hard material, for manufacturingrocket nozzles Isotope boron with strong neutron absorption ability, so borideis used as tame rods and shield allied in nuclear reactor regulator. Addingboron to plastic will hold radiation performance
Accordingto metal powdersupplier, boron is furthermore extensively usedfor glass, ceramic industry, manufacturing high-quality heat-resistantborosilicate glass, glass fibers, optical lens, insulation germane andfiberglass Boron and cobalt, titanium, nickel and the like can be made ofcermet Boron is furthermore used for manufacturing enamel, glaze and so on. Inaddition, boron is further used as a preservative, solder for manufacturingsuperhard abrasive.
