upfu hwemhando yepamusoro hweAmorphous Elemental Boron cas 7440-42-8
High grade Amorphous Elemental Boron upfu cas 7440-42-8
Zita reKemikari: Amorphous Elemental Boron
CAS: 7440-42-8
Kurema kweAtomu: 10.81 (pana 1979 huremu hweatomu hwepasi rose)
Kupisa kwepasi pevhu: 2550℃
Simba guru: 2.34-2.37g/cm3
Kuchena: 88%, 90%, 92%, 95%
Zvimiro:
Boron iri panzvimbo yakakosha pakati pesimbi uye isiri simbi patafura yeperiodic yezvinhu. Hunhu hwayo hwemakemikari hunonyanya kushanda nekuda kwemagetsi ane simba, radius diki yeatomu uye centralized nuclear charge. Inogara yakagadzikana mukupisa kwakajairika, inooxidized kana ichidziiswa kusvika 300℃, uye inopiswa kana ichipiswa kusvika 700℃. Haina kunaka uye haina hwema. Hunhu hwayo hwesimbi hwakafanana nesilicon. Boron inogona kusangana neokisijeni, nitrogen, sarufa, halogen kana kabhoni nezvimwewo. Inogona kusanganiswa zvakananga nemhando dzakasiyana dzesimbi kuti igadzire boronic compounds. Uyezve boron inogonawo kugadziriswa neorganic compounds kuti igadzire mamwe makomponi, umo boron inobatanidzwa zvakananga nekabhoni, kana kuti okisijeni iripo pakati peboron nekabhoni.
Mashandisirwo:
Boron inonyanya kushandiswa mukugadzira simbi, zvemagetsi, zvemishonga, zveceramics, indasitiri yenulear uye indasitiri yemakemikari nezvimwewo, inoshandiswa muchimiro checompound kana kuwedzerwa mune mamwe ma alloys sekuwedzera. Inogona kushandiswa mukunyungudutsa mamwe ma alloy steels akakosha uye semubvisi wegesi wesimbi inonyungudutsa, mudanda rekupisa-kupinza rechubhu inopisira-kupinza muindasitiri, muchina wekudzora weatomic reactor, uye mumafuta ane simba rakawanda eroketi. Chinhu chakakosha pakugadzira halogenatedborons dzakachena zvakanyanya, zvakare chinhu chekugadzira mhando dzakasiyana dze boronic compounds. Simbi zhinji dzakanaka uye dzisingawanzo kuwanikwa dzinogona kutsiviwa uye kuchengetedzwa nadzo. Boron nemakomponi ayo anogonawo kushandiswa sechinokonzeresa mamwe maitiro emakemikari eorganic, nezvimwewo.
Pasuru:
Yakazara ne vacuum mumabhegi ealuminium foil, umo maiswa bhegi repurasitiki.
Huremu hwese 1kg pabhegi, 5kg/bhokisi, 10kg/bhokisi, 25kg/bhokisi
Kuchengetedza:
Inofanira kuchengetwa mudura rine mumvuri, rinofefetedza mweya uye rakaoma. Nguva yayo yekuchengetera igore rimwe chete.
Chigadzirwa ichi chinogona kushandiswa kana chiri chemazuva ese kuburikidza nekuyedzwazve mushure mezuva rakatarwa.
Zvinyorwa zvekuchengetedza:
Chigadzirwa ichi chinoonekwa sechepfu kana uchifema wodya, kuchifema kunokanganisa sisitimu yetsinga, kuchidya kuchaita kuti mudumbu nemudumbu muwedzere chepfu yemudumbu uye boron, kugunzva ganda kana maziso kuchaita kuti muwedzere kunhuhwirira, kupfeka magirazi ekudzivirira, chifukidzo chegauze chinodzivirira guruva, magirovhosi erabha paunenge uchichibata.
