Qhov sib txawv tseem ceeb ntawm fused silica thiab quartz yog fused silica muaj cov iav uas tsis yog-crystalline silica whereas quartz muaj crystalline silica.
Fused silica tseem hu ua fused quartz. Nws yog ib lub khob uas yuav luag dawb huv silica nyob rau hauv ib daim ntawv amorphous. Quartz, ntawm qhov tod tes, yog cov pob zeb hauv av uas muaj silicon thiab oxygen atoms.
Fused Silica yog dab tsi?
Fused silica, tseem hu ua fused quartz, yog iav uas muaj cov silica uas yuav luag dawb huv hauv daim ntawv amorphous. Hom iav no txawv ntawm lwm cov iav uas muaj nyob rau hauv kev lag luam nplai vim tias cov khoom xyaw ntawm cov fused quartz ntau lawm txawv ntawm lwm tus. Cov khoom xyaw no ua rau muaj kev hloov pauv ntawm cov khoom siv kho qhov muag thiab lub cev ntawm cov iav, nrog rau kev txo qis ntawm qhov kub thiab txias. Yog li ntawd, fused silica muaj qhov kub thiab txias ua haujlwm, siab melting kub, thiab lwm yam. Qhov no kuj ua rau cov iav tsis xav tau rau qee yam kev siv.
Daim duab 01: Kev siv ntawm Fused Quartz
Peb tuaj yeem tsim fused silica los ntawm fused / melting siab purity silica xuab zeb uas muaj quartz siv lead ua. Plaub hom fused quartz hauv kev lag luam suav nrog hom I, II, III, thiab IV.
Type I - tsim los ntawm induction melting ntawm ntuj quartz nyob rau hauv lub tshuab nqus tsev inter atmospheres
Hom II - ua los ntawm fusion ntawm quartz siv lead ua hmoov ntawm qhov kub kub
Hom III - tsim los ntawm kev hlawv silicone tetrachloride hauv cov nplaim hluav taws xob hydrogen
Type IV - tsim los ntawm kev kub nyhiab silicone tetrachloride hauv cov dej tsis muaj cov pa roj ntshav
Quartz yog dab tsi?
Quartz yog cov ntxhia hauv cov ntxhia uas muaj silicon thiab oxygen atoms. Nws muaj silicon dioxide (SiO2) molecules. Tsis tas li ntawd, nws yog cov ntxhia tshaj plaws nyob rau hauv lub ntiaj teb crust. Txawm hais tias nws muaj SiO2, qhov rov ua dua ntawm cov pob zeb no yog SiO4. Qhov no yog vim hais tias cov qauv tshuaj ntawm quartz muaj ib tug silicon atom bonded rau plaub oxygen atoms nyob ib ncig ntawm nws. Yog li ntawd, lub geometry nyob ib ncig ntawm silicon atom yog tetrahedral. Txawm li cas los xij, ib qho oxygen atom sib koom ntawm ob lub tetrahedral. Yog li ntawd, cov txheej txheem siv lead ua ntawm cov ntxhia yog hexagonal.
Daim duab 02: Qhov tshwm sim ntawm Quartz
Tsis tas li ntawd, quartz siv lead ua yog chiral. Qhov ntawd txhais tau tias quartz muaj nyob rau hauv ob daim ntawv raws li ib txwm α-quartz thiab kub-kub β-quartz. Daim ntawv alpha tuaj yeem hloov mus rau hauv daim ntawv beta ntawm ib ncig ntawm 573 ° C. Saib ntawm lawv qhov tshwm sim, qee hom quartz tsis muaj xim thiab pob tshab, thaum lwm cov ntaub ntawv muaj xim zoo nkauj thiab translucent. Cov xim ntau tshaj plaws ntawm cov pob zeb no yog dawb, grey, ntshav, thiab daj.
Qhov txawv ntawm Fused Silica thiab Quartz yog dab tsi?
Fused silica lossis fused quartz yog ib khob uas muaj cov silica uas yuav luag dawb huv hauv daim ntawv amorphous. Quartz yog cov ntxhia sib xyaw uas muaj silicon thiab oxygen atoms. Qhov sib txawv tseem ceeb ntawm fused silica thiab quartz yog fused silica muaj cov iav uas tsis yog-crystalline silica thaum quartz muaj crystalline silica. Ntxiv mus, fused silica yog tsim los ntawm fusing / melting siab purity silica xuab zeb uas muaj quartz siv lead ua, thaum quartz ib txwm tshwm sim thiab nws yog industrially npaj los ntawm kev siv "cov noob siv lead ua" (ib qho me me ntawm kev ua tib zoo xaiv quartz) uas cov quartz loj hlob.
Cov hauv qab no infographic teev qhov sib txawv ntawm fused silica thiab quartz hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Fused Silica vs Quartz
Fused silica tseem muaj npe hu ua fused quartz, thiab nws yog ib khob uas muaj cov silica uas yuav luag dawb huv hauv daim ntawv amorphous. Quartz yog cov ntxhia pob zeb uas muaj silicon thiab oxygen atoms. Qhov sib txawv tseem ceeb ntawm fused silica thiab quartz yog fused silica muaj cov iav uas tsis yog-crystalline silica, whereas quartz muaj crystalline silica.
