Qhov sib txawv tseem ceeb ntawm av nplaum thiab ceramic yog cov av nplaum muaj cov khoom siv moistened xws li aluminium silicates thiab crystalline silica, whereas ceramic muaj hlau oxides xws li zirconium oxide, silica oxide lossis silica carbide.
Cov ntsiab lus av nplaum thiab ceramic feem ntau yog muab piv rau hauv thaj chaw ntawm lub lauj kaub tais diav thiab ua cov khoom siv hauv tsev. Cov ntaub ntawv no muaj ntau yam kev siv tseem ceeb.
Clay yog dab tsi?
Av nplaum yog ib yam ntawm cov khoom siv hauv av uas muaj cov av nplaum. Cov khoom no feem ntau txhim kho plasticity thaum nws ntub txaus. Qhov no tshwm sim vim yog cov yeeb yaj kiab molecular ntawm cov dej uas nyob ib puag ncig cov av nplaum. Txawm li cas los xij, av nplaum yuav nyuaj thiab nkig thaum nws nyob hauv lub xeev qhuav lossis thaum cua sov / tua thiab ua tsis yog yas.
Daim duab o1: Pom av nplaum
Feem ntau, av nplaum dawb huv yog xim dawb lossis xim xim. Txawm li cas los xij, cov av nplaum tshwm sim tshwm sim qhia cov xim sib txawv vim muaj cov impurities. Cov xim feem ntau muaj xws li xim liab, xim av lossis xim liab-xim av. Cov xim no yog vim muaj cov hlau oxide sib txuas hauv av nplaum. Qhov tseem ceeb tshaj, av nplaum yog hom qub tshaj plaws ntawm ceramic.
Txij thaum ub, tib neeg tau tshawb pom thiab siv av nplaum ua cov khoom siv rau cov tais diav vim nws cov yas uas tsis yog yas thaum cua sov. Tsis tas li ntawd, cov khoom siv no muaj txiaj ntsig zoo hauv ntau qhov kev lag luam tam sim no, suav nrog kev tsim cov ntaub ntawv, kev tsim cov cement, thiab tshuaj lim dej.
YCeramic yog dab tsi?
Ceramic yog cov khoom tsis muaj zog, tsis yog xim hlau uas tau tawv tawv ntawm qhov kub thiab txias. Cov qauv atomic ntawm cov khoom no los ntawm cov ntaub ntawv xws li crystalline, non-crystalline lossis ib nrab crystalline. Txawm li cas los xij, cov khoom no feem ntau muaj cov qauv crystalline atomic.

Ntxiv mus, peb tuaj yeem faib cov ceramics ua cov tsoos lossis qib siab ceramic feem ntau, nyob ntawm lawv daim ntawv thov. Feem ntau ntawm lawv yog opaque tsuas yog iav. Silica, av nplaum, limestone, magnesia, alumina, borates, zirconia, thiab lwm yam, yog cov khoom siv raw rau ceramics.
Tsis tas li ntawd, cov khoom no yog kev poob siab resistant, siab zog, puas-resistant khoom. Txawm li cas los xij, lawv cov hluav taws xob conductivity tsis zoo. Tsis tas li ntawd, peb tuaj yeem tsim cov khoom siv no los ntawm kev tsim cov tshuaj txhuam hniav uas muaj cov hmoov zoo heev ntawm cov khoom siv raw thiab dej rau hauv cov duab muab thiab tom qab ntawd los ntawm sintering. Vim cov txheej txheem tsim, ceramic yog me ntsis kim dua iav. Tsis tas li ntawd, tej yam ntuj tso ceramics xws li pob zeb, av nplaum, thiab cov plooj (porcelain) kuj tseem siv tau rau lub neej txhua hnub.
Qhov txawv ntawm Av nplaum thiab Ceramic yog dab tsi?
Av nplaum yog ib hom ntawm cov khoom siv hauv av uas muaj cov av nplaum thaum cov ceramic yog cov khoom tsis muaj zog, cov khoom tsis yog xim hlau uas tau hardened ntawm qhov kub thiab txias. Av nplaum yog hom ceramic. Qhov sib txawv tseem ceeb ntawm cov av nplaum thiab ceramic yog cov av nplaum muaj cov khoom siv moistened xws li txhuas silicates thiab crystalline silica, whereas ceramic muaj hlau oxides xws li zirconium oxide, silica oxide los yog silica carbide. Ntxiv mus, av nplaum kilns yog zoo li earthenware kilns thiab yog zoo rau tsawg-hluav taws kub av nplaum tuav thaum ceramic kilns yog zoo rau high-hluav taws kub av nplaum tuav. Tsis tas li ntawd, av nplaum yog pheej yig dua li cov ntaub ntawv ceramic.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm av nplaum thiab ceramic hauv daim ntawv tabular.
Summary – Av nplaum vs Ceramic
Peb tuaj yeem txheeb xyuas av nplaum ua hom ceramic. Tab sis peb siv cov ntsiab lus sib cais vim av nplaum yog cov khoom siv uas muaj ntau dua li lwm hom ceramic. Qhov sib txawv tseem ceeb ntawm cov av nplaum thiab cov ceramic yog cov av nplaum muaj cov khoom siv moistened xws li txhuas silicates thiab crystalline silica, whereas ceramic muaj hlau oxides xws li zirconium oxide, silica oxide los yog silica carbide.
