Silicon hlau 97 nrog zoo zoo

Cov ntsiab lus tseem ceeb ntawm cov hlau silicon 97 yog silicon, thiab nws cov ntsiab lus feem ntau yog nruab nrab ntawm 97% thiab 98% (hauv xyoo tas los no, cov khoom lag luam nrog Si cov ntsiab lus ntawm 99.99% kuj tau suav nrog hauv qeb ntawm cov hlau silicon 97). Ntxiv rau silicon, hlau silicon 97 kuj tseem muaj cov kab tsis huv xws li hlau (Fe), txhuas (Al), calcium (Ca), thiab lwm yam. Txawm hais tias cov ntsiab lus ntawm cov impurities no tsis siab, lawv yuav muaj qee yam cuam tshuam rau kev ua haujlwm. thiab siv cov hlau silicon 97.

Cov txheej txheem ntawm cov hlau silicon 97 feem ntau suav nrog cov kauj ruam ntawm kev npaj cov khoom siv raw, smelting, refining thiab casting. Tom qab ntxuav, tshuaj xyuas thiab ziab, cov ntaub ntawv raw yog yaj ntawm qhov kub thiab txias hauv lub cub hluav taws xob ua ke nrog tus neeg sawv cev txo. Thaum lub sij hawm smelting txheej txheem, cov khoom silicon yog txo los ua hlau silicon 97. Tom qab ntawd, impurities raug tshem tawm ntxiv los ntawm cov txheej txheem refining los txhim kho cov purity ntawm cov khoom. Thaum kawg, cov hlau ua kom zoo silicon 97 raug muab pov rau hauv cov blocks lossis granules rau kev ua haujlwm tom ntej thiab siv.

Nws yog xim hlau silicon 97 muaj qhov tsaus grey luster, siab melting point, zoo tshav kub tsis kam, siab resistivity, thiab yog heev antioxidant. Cov khoom siv lub cev no ua rau cov xim hlau silicon 97 dav siv hauv ntau qhov chaw. Hlau silicon 97 yog ib qho tseem ceeb raw khoom rau kev tsim aluminium alloys. Los ntawm kev ntxiv cov xim hlau silicon 97, cov khoom siv kho tshuab, kev tiv thaiv corrosion thiab thermal stability ntawm aluminium alloys tuaj yeem txhim kho tau zoo, yog li ua tau raws li qhov xav tau ntawm aluminium alloys hauv ntau qhov chaw. Thaum smelting tshwj xeeb hlau thiab non-ferrous alloys, hlau silicon 97 yog siv los ua deoxidizer thiab alloy additive, uas pab tshem tawm oxygen thiab lwm yam impurities nyob rau hauv cov hlau thiab txhim kho cov zoo thiab kev ua tau zoo ntawm cov hlau. Hlau silicon 97 kuj tseem siv tau los tsim cov khoom siv hluav taws xob xws li ceramic resistors thiab ceramic capacitors. Cov khoom siv no tau siv dav hauv cov khoom siv hluav taws xob, khoom siv sib txuas lus thiab lwm yam kev lag luam vim lawv qhov kub thiab txias tsis kam, corrosion kuj thiab cov khoom hluav taws xob zoo.

Silicon hlau 97 yog ib qho tseem ceeb raw khoom rau zus tau tej cov organosilicon tebchaw. Los ntawm cov tshuaj tiv thaiv, silicon hlau 97 tuaj yeem hloov mus rau hauv silicone roj hmab, roj hmab silicone, silicone resin thiab lwm yam khoom siv organosilicon, uas tau siv dav hauv cov txheej txheem, yas, roj hmab thiab lwm yam lag luam. Silicon hlau 97 tuaj yeem siv los tsim cov ntaub ntawv refractory, xws li silica cib, siliceous refractory av nkos, thiab lwm yam. Cov ntaub ntawv refractory no muaj qhov kub thiab txias tsis kam thiab tau dav siv nyob rau hauv kub kub industrial teb xws li steel, non-ferrous hlau, iav, cement, lwm yam.
