Al2O3 nanopowders spherical alpha Alumina for abicah conductive thermal

Ngenxa ye-viscosity yayo enhle, ukuguquguquka, ukusebenza kakuhle koxinzelelo kunye ne-thermal conductivity egqwesileyo, ijeli ye-silica ye-thermal conductive isoloko isetyenziswa njenge-heat dissipation filler ye-IC substrates zezixhobo zombane ezifana nezixhobo zonxibelelwano kunye neekhompyutha. iifayili zomgubo ziquka i-aluminium nitride, i-aluminium oxide, i-zinc oxide, i-beryllium oxide, i-silicon oxide, i-silicon carbide, i-boron nitride, njl. yi-30W/m · K), kwaye sele isetyenziswa ngokubanzi kwiimveliso zokugquma kwindawo yombane ophezulu kunye nezixhobo zokutshintsha ze-UHV.

Amasuntswana e-alumina ane-thermal conductivity ephezulu kufuneka ngokwawo abe neqondo eliphezulu le-crystallinity kunye nokuqina.I-alpha-phase alumina inesakhiwo esine-hexagonal, esona sakhiwo sixineneyo phakathi kweentlobo ezahlukeneyo ze-alumina.Uphononongo lubonise ukuba ukuphakama kwesigaba se-alpha somgubo we-alumina, iikristale ziyikristale enye ngokupheleleyo kunye namasuntswana angqukuva, kwaye kukho iiplanethi ezithile zekristale.Xa uzaliswe kwi-silica gel, uqhagamshelwano oluthile lomgca kunye nomphezulu uya kubonakala xa iinqununu zidibanisa neengqungquthela.Uqhagamshelwano, ngoko ke i-thermal conductivity ye-silica gel inokuphuculwa kakhulu.
