PG uhi Pyrolytic Graphite uhi
Ma ke ʻano he uhi no nā lako graphite i hoʻopaʻa ʻia i hoʻopaʻa ʻia, hoʻokumu ʻia ka pyrolytic graphite (PG) i kahi papa pale impermeable me nā waiwai mechanical, thermal a me nā uila ma mua o ka graphite maʻamau.ʻO ka PG kahi huahana ultrapure me ka nui o ka theoretical density a me ka anisotropy kiʻekiʻe (300 W / mK ma ke kuhikuhi AB a me 3.5 W / mK ma ke kuhikuhi C).ʻAʻole kemika a paʻa ʻo PG i nā wela wela (a hiki i 3000°C).
