Thermal conductivity ntawm iav

iav yog ib tug tsis zoo conductor ntawm tshav kub, nws thermal conductivity yog tsawg, feem ntau nyob rau hauv lub ntau yam ntawm 0.712 ~ 1.340W / (m·K), mas txiav txim los ntawm cov tshuaj muaj pes tsawg leeg ntawm iav, kub thiab xim. Lub thermal conductivity ntawm iav yog ib qho tseem ceeb heev, uas yuav tsum tau nyob rau hauv kiln tsim, iav pwm tsim, iav ntau lawm txheej txheem tshuav nyiaj li cas thiab hais txog. Lub thermal conductivity nce nrog qhov nce ntawm qhov kub thiab txias, thiab λ ntawm cov iav zoo tib yam yog kwv yees li ob npaug thaum nws tau rhuab mus rau qhov muag muag, uas tuaj yeem xam los ntawm cov qauv hauv qab no rau 3.3 siab borosilicate iav. λ=A+BlgT formula: A -- -0.003523;
