Cordierite yog ib hom khoom siv ceramic uas feem ntau siv rau hauv ntau yam kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov rooj tog zaum, catalytic converters, thiab qee hom cookware. Cov muaj pes tsawg leeg ntawm cordierite ceramics feem ntau suav nrog cov khoom tseem ceeb hauv qab no:
1. Magnesium Oxide (MgO)
Feem ntau ntawm magnesium oxide feem ntau pom muaj nyob rau hauv cordierite ceramics, uas pab lawv muaj thermal expansion thiab zoo tiv thaiv thermal shock.
2. Aluminium Oxide (Al₂O₃)
Aluminium oxide yog lwm qhov tseem ceeb, pab ua kom tiav qhov kev xav tau ua ke ntawm cov khoom, xws li kev ruaj ntseg kub thiab qis thermal expansion.
3. Silicon Dioxide (SiO₂)
Silicon dioxide, tseem hu ua silica, feem ntau muaj nyob rau hauv cordierite compositions. Nws cuam tshuam cov txheej txheem ceramic thiab cov khoom.
4. Lwm yam additives
Dhau li ntawm cov khoom tseem ceeb no, cordierite ceramics kuj tseem muaj lwm yam ntxiv rau lawv los txhim kho qee yam khoom lossis ua kom cov txheej txheem tsim tau yooj yim dua. Cov additives no tuaj yeem suav nrog:
- Cov ntsiab lus taug qab
Qee qhov me me ntawm lwm cov ntsiab lus tuaj yeem muaj raws li impurities lossis txhob txwm ntxiv rau lub hom phiaj tshwj xeeb.
- Kev pab ua haujlwm
Ntau yam kev pab cuam, xws li binders, plasticizers, thiab lubricants, tuaj yeem suav nrog los pab txhawb kev tsim thiab tua cov khoom siv ceramic.
Qhov tseeb muaj pes tsawg leeg tuaj yeem sib txawv nyob ntawm qhov kev xav tau ntawm daim ntawv thov thiab cov txheej txheem tsim khoom siv. Cov neeg nyiam cordierite ceramics vim tias lawv tuaj yeem tswj qhov kub thiab txias. Qhov no ua rau lawv zoo rau kev siv qhov twg thermal shock kuj tseem ceeb.
