Iyo gutwika, umwanda udasanzwe mungero ntangarugero urahagaze neza (nka sodium chloride ya sodium, potasiyumu chloride, sodium sulfate, nibindi), niba bidatewe no gutwika no guhumeka, ubu buryo burashobora gukoreshwa kugirango umenye ivu murugero.

[Uburyo bwo Kumenya] Shyira igipfukisho ceramic ceramic (cyangwa nikel crucible) ku itanura ryubushyuhe bwo hejuru (ni ukuvuga itanura rya ver) cyangwa umuriro wa gaze, gutwika kugeza ku buremere buhoraho hafi (hafi isaha 1), ubimure kuri calcium chloride yumye. n'ubukonje kugeza mucyumba cy'ubushyuhe. Umupfundikizo wingenzi wapimwe hamwe kuringaniza yisesengura hanyuma ushyirwa kuri G1 g.

Mugihe kimaze gupimwa cyane, fata icyitegererezo gikwiye (ukurikije ivu riri murugero, ubusanzwe ryitwa garama 2-3), ryavuzwe kuri garama 0.0002, umunwa wuzuye umupfundikizo wumunwa hafi ya bitatu bya kane, hamwe numuriro muke ushushe buhoro buhoro, kora icyitegererezo gahoro gahoro karuboni , nyuma yingenzi mumatanura yamashanyarazi (cyangwa flame ya gaz), ntabwo ari 800℃gutwika hafi yuburemere buhoraho (amasaha agera kuri 3), yimukiye kuri calcium chloride yumye, akonje mubushyuhe bwicyumba, apima. Nibyiza gutwika nyuma yamasaha 2, gukonjesha, gupima, hanyuma ugatwika kumasaha 1, hanyuma ukonje, upima, nkibiri bipima bikurikiranye, uburemere ntibuhinduka, noneho bivuze ko byatwitse burundu, niba ibiro bigabanutse nyuma yo gutwikwa kwa kabiri, noneho igomba kuba ya gatatu yaka, gutwika kugeza bisa nuburemere buhoraho, shiraho garama G.

(G-G1) / uburemere bw'icyitegererezo x100 = imvi%

.

2. Igihe cyo gutwika biterwa nuburemere bwicyitegererezo, ariko gutwika bisa nuburemere buhoraho.

3. Itandukaniro ryo gupima ryaka inshuro ebyiri zikurikiranye byari byiza kuba muri 0,3 mg munsi, itandukaniro ntarengwa ntirishobora kurenga mg 1, urebye nkuburemere muburemere burigihe aribwo.
