Astaamaha
Marka ay timaaddo dhalaalidda birta, saxan saxan ayaa isbeddel oo dhan sameeya!Crucibles garaafyada waaweynu istaagaan sidii qalab lagama maarmaan u ah aasaaska, dukaamada birta, iyo shaybaadhka cilmi-baarista. Maraakiibtan adag waxaa loogu talagalay inay u adkeystaan heerkulka aad u daran iyo shoogga kulaylka daran-ilaa 3000°F xaaladaha qaarkood!
Laakiin maxaa run ahaantii kala sooca garaafyada waaweyn ee garaafyada? Waa awooddooda aan la soo koobi karin si ay si hufan u gutaan kulaylka, iyaga oo hubinaya in birahaagu ay si degdeg ah u gaaraan barta dhalaalka. Tani waxay ka dhigan tahay tamar yar iyo wax soo saar badan hawlgalkaaga.
Markaa, haddii aad dhalaalayso aluminium, naxaas, ama biraha qaaliga ah sida dahabka iyo qalinka, graphite crucible weyn ayaa ah xalka aad tagayso. Maqaalkan, waxaan ku baari doonaa codsiyadooda, astaamaha muuqda, iyo faa'iidooyinka aan la dafiri karin ee ay bixiyaan, kaa caawinaya inaad sameyso doorasho xog ogaal ah oo kor u qaadaysa socodkaaga shaqada. Aan quusno!
Kaarboonka graphite waxay leeyihiin isticmaalyo badan, oo ay ku jiraan:
Awoodda ay ku ilaalinayaan daacadnimada heerkulka sare ayaa ka dhigaya kuwo aan looga maarmin dhammaan noocyada codsiyada warshadaha

Waxaan ku takhasusnay soo saarista garaafyada kaarboon-garaafyada tayada sare leh anagoo adeegsanayna farsamooyinka wax soo saarka ee horumarsan sida riixitaanka isostatic qabow. Cruciblesyadayadu waxay bixiyaan waxqabad heersare ah marka loo eego caabbinta kulaylka, adkeysiga, iyo hufnaanta. Xakamaynta tayada adag eeyada waxay hubisaa in qolof kastaa ay la kulanto heerarka warshadaha ugu sarreeya, taas oo ka dhigaysa doorasho lagu kalsoonaan karo oo loogu talagalay baahidaada warshadeed. Haddii aad ku lug leedahay shubista birta, soo saarista daawaha, ama shaqada aasaaska, alaabadayada waxaa loogu talagalay inay buuxiyaan shuruudahaaga gaarka ah, iyagoo bixiya wareegyo nololeed oo dheer iyo hoos u dhac.
