Cov khoom siv hluav taws xob ceramics yog dab tsi?
Cov khoom siv hluav taws xob ceramics yog cov khoom siv ceramic tshwj xeeb siv hauv cov khoom siv hluav taws xob, feem ntau yog ua los ntawm ceramic hmoov sintered ntawm qhov kub thiab txias. Lawv cov ntaub ntawv raw feem ntau suav nrog cov khoom siv ntxhia thiab cov khoom siv tshuaj. Cov khoom siv ntxhia muaj xws li av nplaum, bentonite, talc, magnesite, fluorite, rutile, thiab corundum; Cov khoom siv tshuaj muaj xws li kev lag luam-qib, tshuaj lom neeg-qib, analytical-qib, thiab spectroscopically-qib cov khoom ntawm qib purity sib txawv.
High-cov khoom siv hluav taws xob ceramic zoo yuav tsum ua tau raws li peb tus qauv hauv qab no:
1. Tshuaj muaj pes tsawg leeg: siab purity, tsis tshua muaj ntau yam thiab cov ntsiab lus ntawm impurities.
2. Particle loj: Tsim nyog particle inch, particle loj tis, thiab particle shape.
3. Cov qauv: suav nrog crystal morphology, stability, tawg, ntom, thiab porosity.
Particle fineness thiab qauv ncaj qha cuam tshuam qhov ntom thiab formability ntawm lub cev ntsuab. Cov khoom zoo nrog cov qauv ua tiav muaj cov haujlwm qis dua, uas tsis zoo rau sintering; conversely, finer hais muaj ntau dua kev ua, uas yog zoo rau sintering.
