7N Giredhi Synthetic Quartz Sand Yapinda Mukugadzirwa Kwemazhinji!

Kwenguva refu, indasitiri yezvemagetsi epasi penyika yangu yanga ichivimba zvakanyanya nekutenga kunze kwenyika ye7N-giredhi repamusoro-jecha repurity quartz, rinoshandiswa mukugadzirwa kwemhando yepamusoro yesemiconductor. Ichi chave chiri chigumbuso chakakosha muindasitiri yeketani. Sezvo chip tekinoroji ichienderera mberi nekushanduka, maitiro epamberi akaisa zvakanyanya kuomarara zvinodiwa pakuchena, kufanana, uye kugadzikana kweiyo quartz substrate.

Nguva pfupi yadarika, fekitari yequartz yekuChina yave neruzivo rwakakura kubva pakuchenesa matombo equartz kuenda ku-kuchena kwemakemikari synthesis. Ivo vakagadzira yakazara tekinoroji cheni inosanganisira precursor tekinoroji, makemikari synthesis maitiro, musimboti wemidziyo yekuvandudza, uye kuongororwa kwekushandisa. Vakabudirira kugadzira uye misa-yakagadzira 7N-giredhi (99.99999%) rejecha requartz rine hutsvina hwakakwana husingasviki 20 ppb, iine kodzero dzakazvimirira dzepfuma yeruzivo. Iri jecha rekugadzira rinoshandiswa mukugadzira semiconductor{{9}grade quartz crucibles, photolithography, uye etching process, pakati pemamwe maitiro akakosha.

Kubudirira uku hakuna tsaona. Kambani iyi yakawana ruzivo rwepamusoro-yakachena quartz synthesis, yakagadzira matekinoroji akasiyana siyana ekudzora magadzirirwo, uye inokoshesesa yakadzama optimization, senge raw material kuchena kutonga, kubviswa kwezvinhu zvakasara, particle size control, dispersion tekinoroji, uye doping process. Aya matekinoroji akashandurwa kuita emakwikwi patent.

Maitiro eKugadzira High-Purity Quartz Sand kubva kuSilicon Tetrachloride by Liquid-Phase Hydrolysis

Chigadzirwa ichi chinoburitsa nzira yekugadzira yakakwira{{0}jecha yequartz yakachena kubva musilicon tetrachloride nemumvura-phase hydrolysis. Maitiro acho anosanganisira mvura-phase hydrolysis yesilicon tetrachloride nemvura. Chigadzirwa chacho chinowachwa, chakasimba-kuparadzaniswa kwemvura, kuomeswa, kukamurwa, kukuya, uye kuvhenekwa kuti chiwane yakakwirira-purity quartz powder. Nhanho yekupisa inosanganisirwa panguva yakaoma-kuparadzaniswa kwemvura, pakati pekugezwa uye kusimba{9}}kuparadzaniswa kwemvura, kana panguva yekugeza kukurudzira kuparara kweorthosilicic acid kuita metasilicic acid, kufambisa nekucheneswa, uye kuderedza marara. Iyo yekuomesa tembiricha ndeye 100-200 dhigirii, uye tembiricha yecalcination ndeye 1300-1500 dhigirii. Iyo calcination yevira dhizaini yakagadziridzwa kuve nechokwadi chekudziya yunifomu uye kudzivirira hupfu agglomeration.

Maitiro Ekugadzirira Ultra{{0}Yakakwirira-Purity Amorphous Silica Synthesized Quartz Sand

Chigadzirwa ichi chinoburitsa nzira yekugadzira ultra-yepamusoro-purity amorphous silica synthesized quartz sand. Kuita uku kunosanganisira kukwirisa-tembiricha nepamusoro{{4}kudzvanywa kweamorphous silica, mineralizer, uye ultrapure water, zvichiteverwa nekupatsanurwa kwakasimba-kumvura panguva yekuyerera. Chigadzirwa chacho chinobva chakuyiwa, asidhi -kusukwa, kucheneswa, uye kuomeswa kuti chiwanikwa. Maitirwo aya anoshandisa simba rereactor kuwana kuparadzaniswa kwakasimba-kwemvura panguva yekuburutsa, kuchengetedza mari. Inoshandisawo amorphous silica, ichizvitutumadza nekuchena kwepamusoro uye kunodzoreka, zvichideredza kushomeka kwe{11}}mhando yepamusoro yematombo equartz munyika yangu. Izvo zvinokonzerwa nejecha requartz rine yakaderera aluminium yemukati uye yakaderera huwandu hwese hupfumbamwe hutsvina.

A Semiconductor-Grade Synthetic Quartz Preparation Process

Iyi semiconductor{{0}grade synthetic quartz process process inosanganisira matanho mana: kugadzirira zvinhu, kubvisa tsvina, kuchinjanisa ayoni, uye kucheneswa kuchembera. Kugadzira zvinhu kunosanganisira kuwedzera alkali simbi silicate kumudziyo uye kunyungudika nekuinyungudusa nemvura yepakati-inopisa yakachena. Kubvisa tsvina kunosanganisira kuwedzera chinobvisa tsvina, kubvongodza, kubvumira musanganiswa kuti ugadzikane, uye kusefa kuparadzanisa heavy metal hydroxides nemushonga uchachinjaniswa. Kuchinjanisa ion kunosanganisira kupfuudza mushonga kuti ugochinjaniswa kuburikidza nekoramu yakasimba{{5}asidhi cation yekuchinjana kubvisa calcium neioni yesodium, zvichiita kuti pave nesol. Kucheneswa kwekuchembera kunosanganisira kubvumira sol kumira kuti ibudise gel, rinobva rachembera, kugeza, kuomeswa, kuputika, sintering, uye ultra{7}}yakakwirira{8}}kucheneswa kuti uwane chigadzirwa. Iyi nzira inoshandisa michina yakasanganiswa kuwedzera otomatiki uye kushanda nesimba.
