PG tube Pyrolytic Graphite tube
Pyrolytic graphite yog siv nyob rau hauv lub caj pas hauv ob sab phlu ntawm foob pob ua ntxaij nozzles, antimagnetic spheres rau satellite cwj pwm tswj, hluav taws xob raj rooj vag, crucibles rau smelting high-purity hlau, txhuam rau voltage regulators, tso chambers ntawm lasers, rwb thaiv tsev cov ntaub ntawv rau high-temperature furnaces thiab epitaxial. wafers rau kev tsim khoom semiconductor.
Non-toxic thiab tasteless;
Ultra-siab purity (99.99%)
Zoo stability, siab ua hauj lwm kub
Zoo thermal conductivity, me me thermal expansion coeffi-
cient, zoo thermal shock kuj
Zoo tshuaj stability, resistant rau acids, alkalis, ntsev thiab lub cev-
ic kuab tshuaj, thiab tsis infiltrate los yog react nrog molten hlau
Tsawg heev outgassing tus nqi
Tsis muaj pores, zoo huab cua nruj, yooj yim machining
