- Cov khoom kub siab kuj: Tsis zoo li cov ntaub ntawv ntsuas kub, graphite tsis tsuas yog tsis soften thaum qhov kub nce ntxiv, tab sis nws lub zog kuj nce ntxiv. Ntawm 2500 degrees Celsius, lub tensile lub zog ntawm graphite yog ob zaug uas ntawm chav tsev kub.
- Thermal conductivity thiab conductivity: vim muaj cov hluav taws xob seem hauv cov pa hluav taws xob hauv cov dav hlau uas nyob ib puag ncig ntawm cov dav hlau uas nyob ib sab Lub thermal conductivity ntawm graphite yog raws nraim li ntawd ntawm cov khoom siv hlau dog dig. Nws muaj cov thermal siab heev ntawm chav tsev kub, tab sis raws li qhov kub nce ntxiv, cov thermal conductivity ua tau. Thaum kawg kub heev, graphite txawm ua ib tug thermal insulator.
- Kev Soj Ntsuam Tshwj Xeeb: nthuav nthuav ntawm graphite yog aniootropic, yog li macroscopic expansion coefficiion tsis loj. Cov xwm txheej ntawm kev hloov pauv kub tam sim no, lub ntim ntawm graphite tsis hloov ntau; Tsis tas li ntawd, nws zoo heev thermal conductivity tau ua rau cov thermal boilal tsis kam ntawm graphite.
- Lubricity: Tus interlayer ntawm graphite yog muaj ntawm cov van der Waas rog, uas muaj lub zog tsis muaj zog thiab muab nws lubricity. Lubrication ntawm graphite nyob ntawm qhov loj me ntawm graphite flakes. Qhov loj dua cov nplai, cov me dua kev sib txhuam coefficient, thiab zoo dua lubrication.
- Tshuaj lom neeg zoo thiab corrosion Kuj: Graphite muaj tshuaj lom neeg muaj zog ntawm chav sov thiab tsis cuam tshuam los ntawm cov kua qaub muaj zog, cov kuab tshuaj alkalis; Cov pa roj carbon atoms nyob rau hauv cov txheej txheem graphite tau raug sib khi ua ke los ntawm kev sib haum xeeb ntawm graphite phosphorus txheeb, uas tsis yog wetted los ntawm Molten Slag thiab muaj cov lus tsis muaj zog heev. Txawm li cas los xij, graphite yog nquag mus rau oxidation nyob rau hauv huab cua, thiab anti oxidation ntsuas yuav tsum tau ua thaum siv cov khoom lag luam refractory.
