Lub microstructure ntawm cov khoom refractory fiber ntau yog feem ntau ua los ntawm cov atoms tsim cov muaju hauv cov txheej txheem, lossis teeb meem tsis sib haum los ua lub khob lub cev. Ib qho atom yog tsim ntawm ib lub roj paug hluav taws xob tsis zoo thiab cov hluav taws xob tsis zoo rau hluav taws xob. Hauv qhov nruab nrab ntawm ib qho me me, cov hluav taws xob sab nraud tsis tshua nyiam los ntawm lub pob hluav taws xob, thiab cov xaim hluav taws xob tau yooj yim ploj. Hauv qee yam xwm txheej sab nraud, kev hloov pauv hluav taws xob tuaj yeem tshwm sim ntawm cov khoom. Cov khoom uas txais hluav taws xob qhia cov hluav taws xob tsis zoo vim muaj cov hluav taws xob ntau dhau, thiab cov khoom poob hluav taws xob qhia tau hluav taws xob zoo. Qhov tseeb, nyob rau hauv kev cuam tshuam ntawm cov yam sab nraud, cov txheej txheem ua rau cov khoom tsim hluav taws xob tsim hluav taws xob yog qhov hu ua hluav taws xob hluav taws xob. Yog tias tus nqi hluav taws xob tsim tawm ntawm cov khoom thiab tsis ntws, nws yog hu ua hluav taws xob zoo li qub lossis hluav taws xob zoo li qub.
Refractory fibers tsoo thiab tshiav sib, thiab tuaj yeem tsim hluav taws xob zoo li qub txawm tias thaum cov fibers raug rub thiab zaws. Yuav luag txhua qhov hluav taws xob zoo li qub tsim los ntawm cov fiber yog tshwm sim los ntawm kev sib txhuam, tab sis nws yog qhov tseem ceeb vim muaj kev sib cuag ntawm ob lub khoom. Kev txhuam txhuam tsuas yog nce qhov chaw sib chwv thiab txo qhov sib tiv tauj. Hauv kev tsim hluav taws xob thiab kev ua tiav, vim muaj qhov txav thiab kev sib txhuam ntawm qhov chaw sib cuag, cov txheej txheem ntawm kev sib cuag thiab sib cais tshwm sim, thiab lub teeb hluav taws xob tsiv ze rau txheej txheej, uas tsim hluav taws xob zoo li qub. Cov kev sim tau ua pov thawj tias thaum kev sib tiv tauj ze ntawm thaj chaw ntawm ob yam khoom yog tsawg dua 2.5 x 10- ~' cm, lawv muaj peev xwm tsim txom pawg neeg.
