Chromium oxide (Cr2O3) yog ib qho inorganic compound

1. Cov tsos mob: Chromium oxide yog ntsuab crystalline particle los yog hmoov.

2. Melting point thiab boiling point: Lub melting point ntawm chromium oxide yog hais txog 2435 ° C, thiab boiling point tshaj 4000 ° C.

3. Ceev: Qhov ceev ntawm chromium oxide yog kwv yees li 5.22 g / cm³.

4. Cov khoom siv tshuaj: Chromium oxide yog ib qho chaw ruaj khov heev uas yog insoluble hauv dej thiab cov kuab tshuaj feem ntau. Nws muaj kev tiv thaiv siab rau acid thiab alkali. Tsis tas li ntawd, chromium oxide muaj kev hnav zoo thiab kub ua haujlwm.

Chromium oxide muaj ntau yam siv

1. Pigment: Vim nws cov xim ntsuab ci, nws feem ntau yog siv los ua cov xim ntsuab hauv kev lag luam xws li ceramics, iav, coatings, thiab plastics.

2. Corrosion inhibitor: Chromium oxide tuaj yeem siv los ua cov tshuaj tiv thaiv corrosion rau steel, alloys, thiab lwm yam hlau kom ntev lawv lub neej.

3. Catalyst: Chromium oxide tuaj yeem siv los ua cov khoom siv tshuaj lom neeg, xws li cov tshuaj ammonia oxidation.

4. Cov khoom siv hluav taws xob: Vim nws cov khoom siv hluav taws xob zoo heev, chromium oxide yog siv dav hauv cov khoom siv hluav taws xob, cov khoom sib nqus, thiab cov txheej txheem kho qhov muag.

Feem ntau muaj ntau txoj hauv kev los tsim chromium oxide:

1. Thermal decomposition method: Thaum tshav kub kub thiab decompose cov chromium ntsev tov los tsim chromium oxide.

2. Oxidation method: Siv cov pa oxidize hlau chromium rau hauv chromium oxide.

3. Hydrothermal txoj kev: Chromium ntsev reacts nrog dej los tsim muaju nyob rau hauv qhov kub thiab txias txias.

Thaum siv chromium oxide, cov ntaub ntawv kev nyab xeeb hauv qab no yuav tsum raug sau tseg:

1. Chromium oxide yog ib yam tshuaj lom, tsis txhob nqus cov khoom thiab ua rau daim tawv nqaij.

2. Thaum lub sijhawm ua haujlwm, cov khoom siv tiv thaiv tus kheej tsim nyog xws li hnab looj tes thiab tsom iav tiv thaiv yuav tsum hnav.

3. Tsis txhob sib xyaw nrog cov tshuaj acidic lossis cov nplaim taws kom tsis txhob muaj cov pa phem lossis hluav taws kub.

4. Thaum khaws cia, nws yuav tsum raug kaw kom tsis txhob muaj kev sib cuag nrog lwm yam tshuaj.
