Hmoov iav kub qis yog cov khoom siv iav inorganic uas tsis yaj thiab tsis sib xyaw uas tsim los rau kev tsim khoom lag luam niaj hnub uas tsis kub heev. Ua los ntawm cov khoom siv raw uas muaj cov khoom huv siab, cov khoom no yog tsim los ntawm kev sib xyaw cov khoom xyaw kom raug, kev sib xyaw kub siab, kev tua dej sai thiab kev sib xyaw ua ke zoo heev. Piv nrog cov hmoov iav ib txwm uas xav tau kub heev rau kev sib xyaw, cov qauv no tsis yaj thiab kub sib txuas tsawg heev, uas ua rau nws zoo tagnrho rau kev tsim khoom loj thiab kev ua cov khoom siv substrate zoo. Nrog kev ruaj khov tshuaj lom neeg zoo heev, lub zog sib txuas ntawm qhov chaw zoo dua thiab kev ua tau zoo heev, cov hmoov iav no tau dhau los ua cov khoom siv tseem ceeb rau kev ua tiav qhov chaw, kev tiv thaiv kev sib khi thiab kev pleev xim zoo nkauj hauv ntau yam kev lag luam teeb pom kev zoo thiab kev ua haujlwm raug.
Cov khoom no muaj cov khoom me me thiab sib npaug zoo, muaj dej thiab tawg zoo. Nws tuaj yeem sib xyaw nrog ntau yam xim inorganic, cov khoom siv ua haujlwm thiab cov kuab tshuaj feem ntau yam tsis muaj kev ntab, nag lossis kev sib sau ua ke, uas ua rau kev sib tov khoom yooj yim dua. Tom qab sintering qis kub, txheej iav muaj lub teeb ci ntsa iab thiab xim ntshiab, thiab nws yuav tsis ploj, tsaus ntuj lossis daj tom qab siv ntev. Lub caij no, cov txheej tiav lawm muaj qhov nyuaj nruab nrab, tiv taus kev sib txhuam zoo thiab tiv taus khawb, uas tuaj yeem tswj tau qhov chaw du thiab zoo txawm tias tom qab kev sib txhuam ntev thiab siv txhua hnub.
Hais txog kev hloov pauv ib puag ncig thiab kev ua haujlwm ntev, peb cov hmoov iav kub qis qhia tau tias muaj kev ruaj khov zoo heev. Nws muaj cov coefficient nthuav dav thermal qis, uas ua rau cov iav kho kom hloov kho rau qhov kub hloov pauv ntau zaus yam tsis muaj kev tawg, tev tawm lossis warping. Cov khoom siv yog inert tshuaj lom neeg, tiv taus cov kua qaub thiab alkali txhua hnub, oxidation thiab noo noo corrosion. Nws kuj muaj cov khoom rwb thaiv tsev hluav taws xob txhim khu kev qha, ua rau nws tsim nyog rau kev tiv thaiv rwb thaiv tsev ntawm cov khoom siv hluav taws xob thiab hluav taws xob. Txawm hais tias siv rau hauv qhov chaw kub tas li lossis sab nraum zoov huab cua hloov pauv, cov khoom tuaj yeem tswj tau qhov ua tau zoo thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom tiav.
Nws siv tau rau ntau yam kev siv rau pej xeem thiab kev lag luam. Hauv kev tsim khoom siv hluav taws xob, nws siv rau kev txheej txheej rwb thaiv tsev, kev sau qhov sib txawv thiab kev kaw ruaj khov ntawm cov khoom siv hluav taws xob me me, txhim kho kev nyab xeeb thiab kev ruaj khov ntawm cov khoom siv hluav taws xob. Hauv kev ua cov khoom siv ceramic thiab iav txhua hnub, nws siv rau kev iav qis-kub, kev kaw ntug thiab kev kho kom zoo nkauj, txhim kho qhov ci ntsa iab thiab cov qauv ntawm cov khoom siv tes ua thiab cov khoom siv niaj hnub. Hauv kev kho cov hlau nto, nws ua haujlwm ua cov txheej txheem tiv thaiv xeb thiab tiv thaiv xeb, hloov cov txheej txheem kub siab ib txwm muaj, txo qis kev siv zog ntau lawm thiab ua kom yooj yim rau cov txheej txheem ntau lawm.
Cov hmoov iav no yooj yim siv rau kev tsim khoom hauv kev lag luam. Nws haum rau ntau txoj kev tsim kho xws li kev txau, kev luam ntawv thiab kev dipping, thiab phim ob qho tib si dej thiab roj tsim cov txheej txheem. Cov txheej txheem sintering yooj yim thiab ruaj khov nrog qhov tsis ua haujlwm tsawg thiab cov khoom tiav siab, uas pab cov chaw tsim khoom tswj cov nqi tsim khoom zoo thiab txhim kho kev ua haujlwm zoo. Cov khoom tsis muaj tshuaj lom, tsis muaj saj thiab muaj kev nyab xeeb rau kev siv hauv kev lag luam txhua hnub. Nws yooj yim rau khaws cia thiab thauj mus los, thiab tuaj yeem khaws cov hmoov ruaj khov thiab ua tiav hauv qhov chaw qhuav thiab cua nkag.
Peb tsom mus rau cov khoom siv hauv kev lag luam uas ruaj khov thiab kho tau raws li koj xav tau. Peb tuaj yeem hloov kho qhov loj me ntawm cov khoom me me, qhov kub ntawm kev sintering, qhov pom tseeb thiab qhov nyuaj raws li cov neeg siv khoom cov txheej txheem tsim khoom tiag tiag thiab cov khoom xav tau. Nrog rau kev sib xyaw ua ke ruaj khov, kev ua tau zoo txhim khu kev qha thiab tus nqi tsim nyog, peb cov hmoov iav uas tsis muaj fusing tau siv dav hauv kev tsim khoom lag luam, pab cov neeg siv khoom txhim kho cov khoom zoo thiab txhim kho kev sib tw ua lag luam tas li.
