Thermal Proderties ntawm Silicon Nitride

Siab melting point

Silicon nitride muaj qhov taw tes zoo nkauj ntawm yuav luag 1900℃thiab tsis yauv ua tshuaj lom neeg lossis cov kev hloov pauv tseem ceeb hauv qhov chaw kub. Qhov no melting point tso cai rau Silicon Nitride los ua kom pom zoo heev thermal stability hauv kev lag luam kub thiab txias heev. Piv txwv li, hauv kev kub sov thiab cua sov cav, silicon nitride muaj peev xwm tswj tau ruaj khov, kev txhim kho tau zoo siv kev ntseeg tau thiab kev nyab xeeb.

Tsawg coefficient ntawm thermal expansion

Cov coefficient ntawm thermal expansion ntawm silicon nitride yog hais txog 2.8 × 10-} ⁶ / degree, uas yog qhov qis dua cov ntaub ntawv hlau. Qhov kev nthuav dav tsawg ntawm thermal expansion muab silicon nitride tau zoo heev thiab tsis yooj yim deform lossis tawg txawm tias tsis muaj qhov hloov kub sai. Nyob rau hauv kev kub-ceev precision twj paj nruag lossis tshuab hluav taws xob, tsawg tsawg thermal nthuav dav ntawm silicon nitride kom paub tseeb vim yog cov khoom siv los ntawm kev nthuav dav.

Zoo tsis kam rau cua sov

Thermal poob siab tsis kam hais txog qhov muaj qhov ruaj khov ntawm cov khoom siv nyob rau hauv cov khoom siv kub, uas feem ntau ua rau cov khoom tawg lossis tawg. Silicon nitride muaj cov thermal zoo thermal poob siab tsis kam thiab tsis raug rau tawg txawm tias thaum txias txias ntawm qhov kub heev. Cov cuab yeej no yog qhov tseem ceeb tshaj plaws hauv cov ntawv thov xws li cov tshuab cua dav hlau thiab kev muaj lub zog muaj kev pabcuam ntev hauv chaw ib puag ncig uas muaj qhov ntsuas kub nquag.
