Chromium Oxide CAS 1308-38-9

Chromium oxide yog siv dav hauv cov txheej txheej, ceramics, metallurgy, catalysts, thiab cov ntaub ntawv tshwj xeeb vim nws cov tshuaj lom neeg tshwj xeeb thiab muaj zog ntsuab pigmentation. Nws ua haujlwm zoo li - cov xim ua tau zoo hauv cov xim, cov xim, cov yas, thiab cov khoom siv hauv tsev uas qhov ntev - xim nrawm, huab cua tsis kam, thiab kev tiv thaiv tshav kub yog qhov tseem ceeb. Nyob rau hauv ceramics thiab iav, nws muab cov xim ntsuab zoo ib yam thiab ua raws li tus neeg sawv cev opacifying, haum rau cov vuas, huv si, thiab cov hniav glazing. Raws li polishing abrasive, chromium oxide yog siv rau hauv kev ua tiav ntawm cov hlau, gemstones, optics, thiab cov cuab yeej txiav. Hauv metallurgy, nws pab tsim cov yeeb yaj kiab tiv thaiv ntawm cov alloys, txhim kho corrosion thiab oxidation tsis kam nyob rau hauv siab - qhov kub thiab txias ib puag ncig xws li aerospace thiab industrial equipments. Chromium oxide kuj tseem siv los ua cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob hauv ntau yam tshuaj tiv thaiv, suav nrog dehydrogenation, hydrogenation, thiab cov txheej txheem organic synthesis. Cov ntawv thov ntxiv suav nrog cov refractories siab heev, siab - cov cements, cov khoom sib nqus, thiab cov khoom tshwj xeeb uas yuav tsum tau muaj zog thiab thermal stability.

Chromium oxide muab kev sib xyaw ua ke ntawm durability, thermal kuj, thiab tshuaj inertness uas ua rau nws muaj kev ntseeg siab rau kev thov kev lag luam. Nws muaj zog tiv thaiv UV hluav taws xob, ya raws, acids, thiab kub siab ua kom ntev - xim tuav tau ntev thaum siv los ua xim, txo cov nqi tu thiab txhim kho cov khoom lag luam. Cov khoom siv lub hardness thiab zoo particle yam ntxwv ua kom meej, zoo polishing, yielding daim iav-zoo li tiav ntawm ob qho tib si hlau thiab optical nto. Nyob rau hauv ceramics thiab refractories, nws ruaj khov nyob rau hauv huab cua kub pab rau deformation kuj, structural kev ncaj ncees, thiab ntev ntawm cov khoom raug thermal shock. Raws li cov catalyst lossis kev txhawb nqa, chromium oxide muaj qhov ruaj khov ntawm qhov chaw siab, txhawb kev ua haujlwm catalytic zoo ib yam thiab txo qis degradation dhau sijhawm. Nws muaj nuj nqi hauv kev tiv thaiv cov txheej txheem txhim kho corrosion kuj ntawm cov hlau, yog li txhim kho kev nyab xeeb, kev cia siab, thiab kev pab lub neej ntawm cov cuab yeej siv nyob rau hauv ib puag ncig hnyav. Thoob plaws txhua qhov kev siv, nws qhov kev ua tau zoo sib xws thiab kev sib raug zoo nrog cov ntaub ntawv sib txawv ua rau nws tus nqi - siv tau thiab ntau yam khoom ntxiv.
