Porogaramu
Fused Silica ni ibikoresho byiza byifashishwa mu gushora imari, inganda, inganda, ubukorikori bwa tekinike, nibindi bikorwa bisaba ibicuruzwa bihoraho, bifite isuku ryinshi hamwe no kwagura ubushyuhe buke cyane.
| Ibigize imiti | Icyiciro cya mbere | Ibisanzwe | Icyiciro cya kabiri | Ibisanzwe |
| SiO2 | 99.9% min | 99.92 | 99.8% min | 99.84 |
| Fe2O3 | 50ppm max | 19 | 80ppm max | 50 |
| Al2O3 | 100ppm max | 90 | 150ppm max | 120 |

Inzira yumusaruro nibiranga
Silica Fuse ikozwe muri silika isukuye cyane, ikoresheje tekinoroji idasanzwe yo guhuza kugirango ireme neza.Silica yacu ya Fused irenze 99% amorphous kandi ifite coefficient nkeya cyane yo kwaguka kwamashyanyarazi no guhangana nubushyuhe bukabije.Fused Silica ni inert, ifite imiti ihamye yimiti, kandi ifite amashanyarazi make cyane.
Ikariso ikoreshwa ifite ibintu byiza cyane byubushyuhe nubumara nkibikoresho byingenzi kugirango imikurire imwe ya kirisiti iturutse ku gushonga, kandi ubuziranenge bwayo buhenze hamwe nigiciro gito bituma ituma bikurura cyane cyane imikurire ya kirisiti-yera cyane.Nyamara, mu mikurire yubwoko bumwe na bumwe bwa kristu, a urwego rwa pirolitike ya karubone irakenewe hagati yo gushonga na quartz ikomeye.
Ibyingenzi Byingenzi bya Silica
Silica ikoreshwa ifite ibintu byinshi bidasanzwe haba mubijyanye nubukanishi, ubushyuhe, imiti na optique:
• Birakomeye kandi birakomeye, kandi ntabwo bigoye cyane gukora imashini no gusya.(Umuntu arashobora kandi gukoresha lazeri micromachining.)
• Ubushyuhe bwo hejuru bwikirahure butuma bigora gushonga kuruta ibindi birahure bya optique, ariko kandi bivuze ko ubushyuhe bwo hejuru bushoboka bushoboka.Nyamara, silika yahujwe irashobora kwerekana devitrification (kristalisiti yaho muburyo bwa cristobalite) hejuru ya 1100 ° C, cyane cyane bitewe n’imyanda imwe n'imwe, kandi ibyo byangiza ibintu byiza.
• Coefficient yo kwagura ubushyuhe iri hasi cyane - hafi 0.5 · 10−6 K - 1.Ibi ni inshuro nyinshi ugereranije nibirahuri bisanzwe.Ndetse no kugabanuka kwinshi kwubushyuhe bwa 10−8 K - 1 birashoboka hamwe nuburyo bwahinduwe bwa silika ihujwe hamwe na dioxyde de titanium, yatangijwe na Corning [4] kandi bita ultra low kwaguka ikirahure.
• Kurwanya ubushyuhe bukabije bwumuriro nigisubizo cyo kwaguka kwinshi kwubushyuhe;hariho impagarara ziciriritse gusa nubwo ubushyuhe bwo hejuru bubaho kubera gukonja vuba.
• Silica irashobora kuba yera muburyo bwa shimi, bitewe nuburyo bwo guhimba (reba hano hepfo).
• Silica ni chimique inert, usibye aside hydrofluoric hamwe nibisubizo bya alkaline.Ubushyuhe bwo hejuru, nabwo burashobora gushonga mumazi (cyane cyane kuruta kristaline).
• Agace kibonerana ni kagari cyane (hafi 0.18 mm kugeza kuri 3 mm), bituma hakoreshwa silika yahujwe gusa mu karere kose kagaragara, ariko no muri ultraviolet na infragre.Ariko, imipaka iterwa ahanini nubwiza bwibintu.Kurugero, imbaraga za infragre zo gukuramo zishobora guterwa nibirimo OH, hamwe no kwinjiza UV biturutse kumyanda (reba hano hepfo).
• Nkibikoresho bya amorphous, silika yahujwe ni isotropic optique - bitandukanye na quartz ya kristaline.Ibi bivuze ko idafite birefringence, kandi indangantego yayo (reba Ishusho 1) irashobora kurangwa na formula imwe ya Sellmeier.
