Fa'amatalaga o oloa

Pyrolytic graphite o loʻo faʻaaogaina i totonu o le faʻaʻaʻa o pusi roketi, antimagnetic spheres mo satelite amio pulea, faitotoʻa faʻaeletoroni, faʻafefeteina mo le faʻafefeteina o uʻamea maualuga-mama, pulumu mo regulators voltage, potu lafoai o lasers, mea faʻapipiʻi mo ogaumu vevela ma epitaxial. wafers mo le gaosiga semiconductor.

Oloa Fa'ailoga

E le oona ma leai se tofo;
Mamaa maualuga-maualuga(99 .99%)
Mautu lelei, Maualuluga galue maualuga
Lelei fa'avevela fa'avevela, la'ititi fa'alautele fa'amama
cient, lelei tete'e te'i vevela
Lelei mautu kemikolo, tetee atu i acids, alkalis, masima ma okeni-
ic solvents, ma e le ofi i totonu pe tali atu i uamea liusuavai
E matua maualalo le fua o le gassing
Leai ni pores, malu lelei le ea, faigofie machining
