Cubic Silicon Carbide (β-SiC)
Cubic Silicon Carbide (β-SiC)
Cubic silicon carbide ceramic powder o se efuefu-lanumeamata pauta. O lona fuala'au mole kemikolo o le: SiC, mole mamafa 40.10, density 3.2g/cm3, liusuavai 2973 ℃, fa'alumaina fa'alauteleina 2.98×10-6K- 1.
Silicon carbide ceramic pa'u e maualuga le mama, vaapiapi vaega tufaina tele, pores laiti, sintering gaoioiga maualuga, fausaga tioata masani, conductivity vevela lelei, ma o se semiconductor e mafai ona tetee oxidation i le vevela maualuga; β-SiC whiskers e umi Large diameter ratio, maualuga maualuga le maeʻa, maualuga maualuga le fua faatatau, ma le maualalo o mea e maua i totonu o le 'ava, o lona faatinoga e sili atu nai lo isi pe faʻatofuina i totonu o se siʻosiʻomaga pala, tele fale gaosi oloa ma mining, pe faʻaalia i le vevela e sili atu i le 1400 ° C. Fa'atauga fa'atauga po'o fa'amea u'amea, e aofia ai fa'amea vevela ultrahigh.

Fa'aoga autu o le silicon carbide: Xinli Abrasive e mafai ona tu'uina atu le silicon carbide mo fa'aoga eseese, e aofia ai le hexagonal po'o le rhombohedral α-SiC ma le kupita β-SiC ma le β-SiC whiskers. O mea tu'ufa'atasi e fa'apipi'i mai i le silicon carbide ma palasitika, u'amea, ma sima e mafai ona fa'aleleia atili ai ona meatotino eseese. Ona o le maualuga o le vevela, maualuga le malosi, ma le maualuga o le vevela, o loʻo faʻaaogaina lautele i mea eletise atomic, masini vailaʻau, gaosiga o le vevela, ma mea eletise ma eletise. , semiconductor fanua, eletise faʻavevela vaega ma tetee, ma isi. E mafai foi ona faʻaaogaina i abrasives, abrasive mea faigaluega, faʻalauteleina mea refractory, ma ceramics lelei.
cubic silicon carbide ofo atu le tele o talosaga i le tele o alamanuia, aemaise lava i le eletise maualuga, masini RF, eletise eletise, semiconductor substrates, siosiomaga maualuga-vevela, sensors, ma optoelectronics.
