PG txheej Pyrolytic Graphite txheej
Raws li cov txheej txheem txheej txheem graphite, pyrolytic graphite (PG) tsim cov txheej txheem tiv thaiv impermeable nrog cov khoom siv hluav taws xob, thermal thiab hluav taws xob tshaj li cov qauv graphite.PG yog ib qho khoom siv ultrapure nrog ze theoretical ntom ntom thiab siab anisotropy (300 W / mK nyob rau hauv AB kev taw qhia thiab 3.5 W / mK nyob rau hauv C kev taw qhia).PG yog chemically inert thiab ruaj khov ntawm qhov kub thiab txias (txog 3000 ° C).
