Thermal Proderties ntawm Silicon Nitride

Siab melting taw tes silicon

Nitride muaj qhov pom melting ntawm yuav luag 1900 degree thiab tsis yauv tsis zoo rau kev ua tsis zoo lossis cov kev hloov pauv tseem ceeb hauv qhov chaw siab. Qhov no melting point tso cai rau Silicon Nitride rau nthuav qhia cov cua sov zoo heev hauv kev lag luam sov thiab kub heev. Piv txwv li, hauv cov cua sov kub thiab cov dav hlau cav, silicon nitride muaj peev xwm tswj tau ruaj khov, ua tau zoo txhim kho kev ntseeg tau thiab kev nyab xeeb ntawm cov khoom siv.

Tsawg coefficient ntawm thermal expansion

Cov coefficient ntawm thermal expansion ntawm silicon nitride yog hais txog 2.8 10-} ⁶ ⁶ ⁶ ⁶ / degree, uas yog qhov ntau dua li cov khoom siv hlau. Xws li cov coefficient ntawm thermal expansion muab silicon nitride tau zoo heev, nws tsis yooj yim deformed lossis tawg txawm tias muaj kev hloov pauv sai sai. Nyob rau hauv kev kub-ceev cov twj paj nruag lossis tshuab hluav taws xob, qhov tsis muaj zog thermal nthuav dav ntawm silicon nitride kev ua haujlwm zoo yog qhov tseeb ntawm cov khoom siv vim yog cov khoom siv thermal.

Zoo thermal poob siab

Kev ua hauj kub kub tsis kam lees txog qhov ruaj khov ntawm cov khoom siv nyob rau hauv qhov tseeb hloov pauv hauv qhov kub thiab txias, feem ntau yog cov khoom siv hluav taws xob tsis tshua muaj kev tawg. Silicon nitride muaj kev tiv thaiv zoo heev rau cov cua sov thiab tsis muaj kev cuam tshuam kom tawg, txawm tias muaj cua txias sai sai. Cov cuab yeej no yog qhov tseem ceeb tshaj plaws hauv cov ntawv thov xws li cov tshuab cua dav hlau thiab tso cai rau koj kom muaj kev pabcuam ntev nrog kev hloov pauv kub zaus.
