MuSi uye FeSi kugadzirwa, iyo huru Si sosi iSiO2, muchimiro chequartz. Kuita neSiO2 kunogadzira SiO gasi iro rinowedzera kuita neSiC kuenda kuSi. Munguva yekupisa, quartz inoshandura kune mamwe maSiO2 magadzirirwo ane cristobalite seyakagadzika yepamusoro-tembiricha chikamu. Shanduko kune cristobalite inzira inononoka. Mwero wayo wakaongororwa kune akati wandei maindasitiri equartz masosi uye yakaratidzwa kuti inosiyana zvakanyanya pakati pemhando dzakasiyana dzequartz. Mimwe misiyano yehunhu panguva yekudziya pakati peaya maquartz masosi, akadai sekunyorovesa tembiricha uye kuwedzera vhoriyamu, zvakadzidzwawo. Iyo quartz-cristobalite chiyero ichakanganisa chiyero chemaitiro anosanganisira SiO2. Mhedzisiro yeindasitiri uye zvimwe zvinorehwa nemusiyano wakaonekwa pakati pemhando dzequartz zvinokurukurwa. Mubasa razvino, nzira nyowani yekuyedza yakagadziridzwa, uye kuferefetwa kwemamwe akati wandei equartz masosi kwakasimbisa iyo yekutanga yakaonekwa musiyano mukuru pakati peakasiyana masosi. Kudzokororwa kweiyo data kwakadzidzwa uye mhedzisiro yemhepo yegesi yakaongororwa. Migumisiro yebasa rekutanga inosanganiswa sehwaro hwehurukuro.
Fused quartz ine yakanakisa kupisa uye makemikari zvimiro se crucible zvinhu zveimwe kristaro kukura kubva mukunyunguduka, uye kuchena kwayo kwepamusoro uye kudhura kwakaderera kunoita kuti iwedzere kukwezva mukukura kwemakristaro akanyanya-kuchena. Zvisinei, mukukura kwemamwe marudzi emakristasi, chidimbu chepyrolytic carbon coating chinodiwa pakati pekunyunguduka uye quartz crucible. Muchikamu chino, tinotsanangura nzira yekushandisa pyrolytic carbon coating ne vacuum vapor transport. Iyo nzira inoratidzwa kuti inoshanda mukubereka zvakati yunifomu coating pahupamhi hwehukuru hwecrucible uye maumbirwo. Mhedzisiro yepyrolytic kabhoni coating inoratidzwa ne optical attenuation zviyero. Mune imwe neimwe nzira yekupfekedza, ukobvu hwekuputira hunoratidzwa kuswedera kune chekupedzisira kukosha nemuswe wakajeka sezvo nguva yepyrolysis ichiwedzera, uye avhareji ukobvu hunowedzera zvakanyanya mumutsara nereshiyo yehuwandu hweiyo inowanikwa hexane vapor kusvika pamusoro penzvimbo yepyrolytic. coating. Quartz crucibles yakaputirwa neichi maitiro akashandiswa kubudirira kukura kusvika ku2-in-diameter Nal single crystals, uye mhando yepamusoro yeNal crystal yakawanikwa ichivandudza sezvo ukobvu hwekuputira hunowedzera.
