Kev faib tawm ntawm silica thiab nws daim ntawv thov
Silica yog ib hom ore thiab muaj peev xwm siv dav. Raws li qhov sib txawv muaj pes tsawg leeg thiab cov khoom ntawm silica, nws tuaj yeem muab faib ua ntau hom. Daim ntawv no yuav qhia txog kev faib tawm ntawm silica thiab nws daim ntawv thov hauv ntau qhov chaw.
Ua ntej, silica classification
Quartz: Quartz yog ib hom silica, nws cov khoom tseem ceeb yog silicon dioxide (SiO2). Quartz siv lead ua muaj siab hardness, siab melting point thiab kub tsis kam, thiab yog ib qho tseem ceeb muaj raw khoom. Quartz feem ntau yog siv rau hauv kev tsim iav, kev tsim khoom ceramic, kev lag luam hluav taws xob thiab cov khoom siv hauv tsev.
Quartz xuab zeb: Quartz xuab zeb yog cov pob zeb hauv av tsim los ntawm cov khoom zoo quartz. Nws muaj hardness siab, hnav tsis kam thiab tshuaj lom neeg ruaj khov, thiab yog ib qho ntawm cov khoom siv raw hauv kev tsim kho, iav, casting, abrasive thiab lwm yam lag luam.
Siliceous pob zeb: Siliceous pob zeb yog ib lub pob zeb uas muaj ntau cov siliceous minerals, xws li quartz, feldspar, thiab lwm yam. Siliceous pob zeb muaj nyob rau hauv lub ntiaj teb crust thiab yog ib qho tseem ceeb ntawm cov khoom siv hauv tsev thiab cov khoom siv kho kom zoo nkauj.
Wollastonite: Wollastonite yog cov carbonate ore nrog cov ntsiab lus silicon siab. Nws yog feem ntau siv hauv metallurgy, iav tsim thiab cov khoom siv hauv tsev.

2. Daim ntawv thov teb
Kev lag luam iav: silica yog ib qho tseem ceeb raw cov ntaub ntawv rau iav manufacturing. Lub siab purity thiab tshuaj stability ntawm quartz thiab quartz xuab zeb ua rau lawv zoo tagnrho rau kev tsim ntau yam khoom iav, xws li iav ca, iav kho qhov muag, thiab fiber ntau optics.
Kev lag luam Electronics: Silica muaj cov ntawv thov tseem ceeb hauv kev lag luam hluav taws xob. High purity quartz yog siv los ua cov khoom siv semiconductor, hnub ci vaj huam sib luag thiab cov khoom siv hluav taws xob xws li cov kua siv lead ua kua.
Cov khoom siv hauv tsev: silica thiab nws cov derivatives yog siv dav hauv cov khoom siv hauv tsev. Quartz xuab zeb feem ntau yog siv rau hauv kev npaj pob zeb, cement thiab mortar, thiab cov pob zeb siliceous tuaj yeem siv rau lub tsev pob zeb thiab kho kom zoo nkauj sab hauv.
Kev lag luam tshuaj: Silica kuj tseem muaj cov ntawv thov tseem ceeb hauv kev lag luam tshuaj. Nws yog siv los ua cov khoom siv raw rau kev sib txuas ntawm cov khoom siv silicone, xws li roj silicone, silicone roj hmab thiab silicone resin.
Lwm yam kev lag luam: Silica kuj tau siv dav hauv metallurgy, kev ua liaj ua teb, cov tais diav thiab dej kho thiab lwm yam. Hauv kev lag luam metallurgical, silica feem ntau yog siv rau hauv kev npaj cov alloys thiab cam khwb cia hlau. Hauv kev ua liaj ua teb, silica tuaj yeem siv los ua cov av txias los txhim kho cov kab mob tiv thaiv thiab tawm los ntawm cov nroj tsuag.
Nyob rau hauv luv luv, silica yog ib qho tseem ceeb ore, uas yuav muab faib ua ntau hom raws li nws muaj pes tsawg leeg thiab cov khoom. Ntau hom silica tau siv dav hauv ntau qhov chaw, suav nrog kev lag luam iav, kev lag luam hluav taws xob, khoom siv hauv tsev thiab kev lag luam tshuaj. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho kev lag luam, daim ntawv thov kev cia siab ntawm silica yuav dav dua.
