Itanura ryubushyuhe bwo hejuru cyane rikoresha sisitemu ya vacuum (ikusanyirizwa hamwe nibice nka pompe vacuum, ibikoresho byo gupima vacuum, valve vacuum, nibindi) mumwanya wihariye wurwobo rw'itanura kugirango bisohore igice cyibikoresho mumyanya yumuriro. , ku buryo umuvuduko uri mu kiziba cy'itanura utarenze umuvuduko usanzwe w'ikirere. , umwanya uri mu cyuho kugirango ugere kuri vacuum, ni itanura rya vacu.
Itanura ryinganda nitanura ryubushakashatsi ryashyutswe nibintu bishyushya amashanyarazi hafi ya vacuum. Ibikoresho byo gushyushya ibidukikije. Mu cyumba cy'itanura gifunzwe n'icyuma cyangwa ikirahure cya quartz, gihujwe na sisitemu yo hejuru ya vacuum ikoresheje umuyoboro. Urwego rwa vacuum rw'itanura rushobora kugera kuri 133 × (10-2 ～ 10-4) Pa. Sisitemu yo gushyushya mu itanura irashobora gushyukwa mu buryo butaziguye inkoni ya karubone ya silicon cyangwa silicon molybdenum, kandi irashobora no gushyukwa no kwinjiza inshuro nyinshi. Ubushyuhe bwo hejuru bushobora kugera kuri 2000 ℃. Ahanini ikoreshwa mu kurasa ceramic, gushonga vacuum, gutesha agaciro ibice byumuyagankuba, annealing, gukata ibice byibyuma, no gufunga ceramic nicyuma.
Isosiyete yacu irashobora gukora ibicuruzwa bya tungsten na molybdenum bikoreshwa mu ziko ry’ubushyuhe bwo hejuru, nk'ibikoresho byo gushyushya, ingabo zishyushya ubushyuhe, ibikoresho bifatika, ibikoresho bifatika, inkoni zifasha, electrode ya molybdenum, ibinyomoro n'ibindi bice byabigenewe.
