Daahan PG Pyrolytic Graphite daahan
Sida dahaarka loogu talagalay qalabka garaafyada ee la shaabadeeyey, graphite pyrolytic (PG) waxay samaysaa lakab ilaalin aan la dhaafin karin oo leh qalab farsamo, kulayl iyo koronto oo ka baxsan kuwa garaafka caadiga ah.PG waa badeecada ultrapure leh cufnaanta aragti dhow iyo anisotropy sare (300 W/mK jihada AB iyo 3.5 W/mK jihada C).PG kiimiko ahaan waa mid aan firfircoonayn oo deggan heerkul aad u daran (ilaa 3000°C).
Aan sun ahayn oo aan dhadhamin;
Nadiifin aadka u sarreeya (99.99%)
Degenaansho wanaagsan, Heerkul sare oo shaqeynaya
Dhaqdhaqaaqa kulaylka wanaagsan, fidinta kulaylka yar
qadiimiga ah, caabbinta shoogga kulaylka wanaagsan
Degganaanshiyo kiimiko oo wanaagsan, adkaysi u leh asiidhka, alkalis, cusbada iyo xubnaha-
ic dareerayaasha, oo aan dhex gelin ama ka falcelin birta dhalaalaysa
Heerarka gaaska oo aad u hooseeya
Daloolo ma laha, cidhiidhi hawo oo wanaagsan, mashiin fudud
