• Cov Kev Qhia Tiag:

  1. purity: Purity yog ib qho tseem ceeb ntawm kev ua qauv ntawm quartz iav. Cov ntsiab lus ntawm SiO2 nyob rau hauv cov cuaj ciam uas niaj hnub yog ntau dua 99.99%. Cov ntsiab lus ntawm SiO2 nyob rau hauv high purity hluavtaws quartz iav yog saum toj no 99.999%.
  2. Kev kho qhov muag: Sib piv nrog cov iav nplaum iav, lub iav pobzeb pob tshab muaj kev pom zoo heev ntawm cov kab nrig tagnrho. Hauv cheebtsam infrared thiab pom lub teeb pom kev zoo, lub spectral transmittance ntawm quartz iav yog zoo dua li cov iav zoo tib yam. Hauv thaj av ultraviolet spectral tshwj xeeb tshaj yog cov luv yoj ultraviolet spectrum, lub khob iav yog zoo dua li lwm yam.
  3. Kub kub: Cov yam ntxwv thermal ntawm quartz iav muaj xws li kub tiv taus, thermal ruaj khov, hluav taws xob hloov pauv ntawm lub siab kub, meej txog cov cua sov thiab cov thermal conductivity, cov khoom siv crystalline (tseem hu ua crystallization lossis permeability) thiab qhov kub hloov pauv. Lub quartz iav thermal nthuav coefficient yog 5.5 × 10-7cm / cm ℃ li 1/34 ntawm tooj liab & 1/7 ntawm borosilicate. Cov yam ntxwv no tau siv rau hauv kev kho qhov muag ntawm lub teeb tsa qhov muag, lub qhov rai qhov kub thiab qee yam khoom xav tau qhov rhiab siab rau kev hloov pauv mus rau qhov tsawg kawg nkaus. Quartz iav raws li qhov nthuav dav coefficient yog me me, nws muaj qhov kub hloov ua haujlwm siab, pob tshab quartz iav rau hauv qhov cub hluav taws xob ntawm 1100 ℃ hauv qab cua sov 15 feeb, thiab tom qab ntawd mus rau hauv cov dej txias, uas tuaj yeem tiv taus 3-5 ncig tsis muaj kev sib tawg. Qhov muag muag ntawm quartz iav yog siab heev xws li cov pob tshab iav quartz yog 1730 ℃, yog li qhov siv kub tsis tu ncua ntawm cov ntsuas quartz yog 1100 ℃ -1200 ℃, 1300 ℃ tuaj yeem siv hauv lub sijhawm luv.
  1. Kev tshuaj lom neeg: Quartz iav yog cov tshuaj zoo acid. Nws cov tshuaj stability yog sib npaug 30 lub sij hawm ntawm cov kua qaub tawv tawv, 150 lub sij hawm ntawm cov xim nickel chromium alloy thiab hom zuaj ntawm cov kub thiab cov ntaub ntawv concentrated acid superiority tshwj xeeb tshaj yog tshwj xeeb tshaj yog cov hydrofluoric acid thiab 300 ℃ phosphate. Lub quartz iav tsis tuaj yeem ua eroded los ntawm lwm cov kua qaub, kua qaub qe, kua qaub, hydrochloric acid thiab aqua regia ntawm kev kub.
  1. Cov khoom vaj khoom tsev: Cov khoom sib xws ntawm cov iav quartz zoo ib yam li cov neeg ntawm lwm cov iav, thiab lawv lub zog nyob ntawm cov kab nrig me me nyob rau hauv lub khob. Modulus ntawm elasticity, tensile zog thiab flexural zog nce nrog nce kub, feem ntau yog ncav lub siab tshaj plaws ntawm 1050-1200 ℃. Pom zoo rau cov neeg tsim tawm nrog kev sib zog muaj zog yog 1.1 * 109Pa thiab kev tuav pov hwm lub zog 4.8 * 107Pa.
  1. Cov cuab yeej hluav taws xob: Quartz iav muaj qhov cim tseg ntawm alkali hlau ions uas yog ib qho kev tsis ua haujlwm. Nws lub dielectric poob yog heev me me rau txhua lub sijhawm. Raws li cov cuab yeej insulators, nws cov khoom hluav taws xob thiab khoom siv dag zog zoo dua li cov ntawm lwm cov ntaub ntawv. Ntawm qhov kub thiab txias, qhov kev ntseeg ntawm cov pob zeb ntawm lub iav yog 1019ohm cm, uas yog sib npaug ntawm 103-106 lub sijhawm ntawm cov iav zoo tib yam. Lub rwb thaiv tsev ntawm cov tawv dawb los ntawm lub cev kub yog 43 txhiab volts / hli.
  1. Hloov siab: Raws li, lub zog tensile yog siab heev tshaj 4 lab phaus ib square inch, optical iav ntawm tib lub thickness ntawm anti-dynamic zog yog 3 ~ 5 lub sij hawm ntawm zoo tib yam iav thiab dabtsi yog khoov zog yog 2 ~ 5 lub sij hawm ntawm zoo tib yam iav. Thaum cov iav puas ntsoog ntawm sab nraud quab yuam, cov khib nyiab feem ntau ua rau obtus kaum uas txo qhov raug mob rau tib neeg lub cev.
  1. Homogeneity: Cov tshuaj lom neeg muaj pes tsawg leeg yuav ua raws li lub cev nqaij daim tawv uas ua rau txo cov kab nrib, kab npuas, impurities, turbidity, deformation thiab hais txog. Hauv lub cuab lub cev thiab kev sib cai, nws muaj kev sib txig sib luag los txhawm rau xyuas kom ua tau zoo.
