Al2O3 nanopowders spherical alpha Alumina kuri silicone yumuriro

Kubera ubwiza bwayo bwiza, guhindagurika, imikorere myiza yo guhonyora hamwe nubushuhe buhebuje bwumuriro, gelika ya silika itwara ubushyuhe ikunze gukoreshwa nkuzuza ubushyuhe bwo gukwirakwiza ubushyuhe bwa IC substrate yibikoresho byamashanyarazi nkibikoresho byitumanaho na mudasobwa. ifu yuzuza ifu irimo nitride ya aluminium, oxyde ya aluminium, okiside ya zinc, okiside ya beryllium, okiside ya silicon, karbide ya silicon, nitride ya boron, nibindi. Muri bo, alumina ntabwo ifite imiterere myiza yo gukingira gusa, ariko kandi nubushyuhe bwayo ntabwo ari buke (ubushyuhe busanzwe bwubushyuhe bwumuriro ni 30W / m · K), kandi yakoreshejwe cyane mubicuruzwa byokwirinda mubijyanye na voltage nini hamwe nibikoresho bya UHV.

Ibice bya Alumina bifite ubushyuhe bwinshi bwo hejuru bigomba kuba ubwabyo bifite urwego rwo hejuru rwa kristu kandi rukomatanya.Alpha-phase alumina ifite imiterere ya mpande esheshatu, niyo miterere yuzuye muburyo butandukanye bwa alumina.Ubushakashatsi bwerekanye ko urwego rwo hejuru rwa alfa ya poro ya alumina, kristu ni kristu imwe rwose hamwe nuduce duto duto, kandi hariho indege zimwe na zimwe za kirisiti.Iyo yuzuyemo silika gel, umurongo runaka uhuza hamwe nubuso bizagaragara mugihe ibice bihuye nibice.Menyesha, bityo ubushyuhe bwumuriro wa silika gel burashobora kunozwa cyane.
