Silicon Nitride Ceramic

Silicon nitride ceramics (Si3N4)

Silicon nitride o se sima efuefu ma maualuga gau gau, e sili atu le tete'i vevela vevela, ma e fai si le mafai ona fa'aogaina i u'amea liusuavai.

I le faʻaaogaina o nei uiga, e faʻaaogaina i totonu o le afi afi afi e pei o vaega afi afi, masini uʻamea blowpipe nozzles, ma isi, aemaise lava vaega e manaʻomia ona faʻaaogaina i siosiomaga faigata e pei o le vevela.

Faʻatasi ai ma le maualuga o le faʻaogaina o le ofuina ma le maualuga o le malosi faʻainisinia, o ana faʻaoga i le faʻaaogaina o vaega taʻavale, faʻataʻamilomilo paʻu paʻu ma semiconductor gaosiga o meafaigaluega faʻapitoa o loʻo faʻalauteleina pea.
