Aluminium nitride ceramic ikoreshwa mubice bikwirakwiza ubushyuhe nibice birwanya ruswa
Ibyiza bya Aluminium Nitride Ceramics
1. Umuyoboro mwinshi
Ceramics ya aluminium nitride ifite ubushyuhe bwinshi, kandi nubushyuhe bwumuriro buri hejuru ya 220 ~ 240W / m · K, bikubye inshuro 2 ~ 3 zububiko bwa silikate. Ubu bushyuhe bwinshi bwumuriro burashobora gukemura neza ikibazo cyo gukwirakwiza ubushyuhe bwibikoresho bya elegitoroniki, bityo bikoreshwa cyane mubikorwa bya elegitoroniki.
2. Gukingirwa cyane
Aluminium nitride ceramic nigikoresho cyiza cyane cyokwirinda hamwe na dielectric ihoraho. Ibi bivuze ko ishobora gutandukanya neza ibintu byumuzunguruko no kwirinda imiyoboro migufi nubushyuhe bukabije.
3. Kurwanya ruswa nyinshi
Ceramics ya aluminium nitride ifite imbaraga zo kurwanya ruswa nyinshi kuri acide, shingiro hamwe na solge organic. Ibi bituma ihitamo neza mubikorwa bya shimi na farumasi.
4. Imbaraga zikomeye
Ceramics ya aluminium nitride ifite imbaraga zo gukanika, kandi imbaraga zunamye no gukomera kuvunika ni 800MPa na 10-12mpa · m1 / 2. Izi mbaraga nini hamwe nubukomezi bukabije bituma ikoreshwa cyane mubikoresho byo gutema, ibice birinda kwambara.
Gukoresha Aluminium Nitride Ceramics
1. Inganda za elegitoroniki
Mu nganda za elegitoroniki, aluminium nitride ceramics ikoreshwa cyane cyane mugukora ingufu nyinshi nibikoresho bya elegitoroniki byihuta. Bitewe nubushyuhe bwo hejuru bwumuriro nubushakashatsi buhebuje, bikemura neza ikibazo cyo gukwirakwiza ubushyuhe bwibikoresho bya elegitoroniki, kandi bikanemeza ko ibikoresho bya elegitoroniki byizewe cyane. Byongeye kandi, ceramics ya aluminium nitride irashobora kandi gukoreshwa mugukora ibikoresho bya microwave nibikoresho bya milimetero, kuzamura imikorere no gutuza kwibikoresho byitumanaho.
Inganda zimodoka
Mu nganda zitwara ibinyabiziga, ceramique ya aluminium nitride ikoreshwa cyane cyane mu gukora moteri, moteri ya silinderi hamwe na feri. Bitewe no kwihanganira kwangirika kwinshi nimbaraga za mashini nyinshi, irashobora gukomeza gukora neza mubushyuhe bwinshi hamwe nibidukikije bikaze igihe kirekire. Byongeye kandi, aluminium nitride ceramics irashobora kandi gukoreshwa mugukora ibyuma bya gaze kugirango hamenyekane ibice byangiza mumodoka kandi bitange umusingi wo gukora moteri.
3. Umwanya mwiza
Mu rwego rwa optique, ceramics ya aluminium nitride ifite ubushyuhe bwinshi nubushyuhe buhebuje bwumuriro, bityo ikoreshwa cyane mugukora lazeri ikora cyane, firime optique na fibre optique nibindi bikoresho byingenzi bya optique. Byongeye kandi, ceramique ya aluminium nitride irashobora kandi gukoreshwa mugukora ibikoresho bisobanutse nka spekrometrike, ibyuma byerekana ubushyuhe bwo hejuru hamwe na disiketi ya infragre, bigateza imbere ukuri kwizerwa.
4. Umwanya wa Semiconductor
Isahani yo gushyushya ibikoresho bya semiconductor ikoresha ibiranga ubushyuhe bwo hejuru bwumuriro mwinshi, aside na alkali irwanya kandi ikambara imyenda ya aluminium nitride ceramics. Nyamara, isahani ya aluminiyumu ya nitride iracyari mu bushakashatsi n’iterambere mu Bushinwa, ariko ni igice cy’ingirakamaro mu gukora chip
