Bolfoarmige aluminiumoxidepoeder foar termyske ynterfacematerialen
produkt Omskriuwing
HRK rige bolfoarmige aluminiumoxide wurde produsearre troch hege temperatuer melting-jet metoade ûntwikkeljen op gewoane ûnregelmjittige foarm Al2O3, en dan ûndergiet screening, suvering en oare prosessen te krijen it definitive produkt.De verkregen alumina hat hege spheroidization taryf, kontrolearber dieltsje grutte ferdieling en hege suverens.Fanwegen syn unike eigenskippen lykas hege termyske conductivity en goede mobiliteit, It produkt is in soad brûkt as de filler fan termyske ynterface materialen, termyske engineering plestik en aluminium-basearre Koper-Clad Laminates ensafuorthinne.
