Titanium-aluminium carbide (TI-Al carbide) yog hom tshiab ntawm peb txheej txheej ceramic, cov khoom siv, uas tau txhawj xeeb los ntawm cov ntaub ntawv tshawb fawb thiab tus kws tshaj lij vim nws cov khoom tshwj xeeb.
Titanium aluminium carbide (Ti2AlC) belongs rau hexagonal crystal system, thiab muaj cov yam ntxwv ntawm cov hlau thiab ceramics: nws muaj tib lub conductivity thiab tshav kub conduction li hlau, tab sis kuj muaj tib lub siab elastic modulus thiab zoo heev kub-kub kho tshuab zog xws li ceramic , nrog cov zoo conductivity thiab kub conduction muaj peev xwm, siab elastic modulus thiab tsis Vickers hardness, thiab zoo puas kuj muaj peev xwm.

Nws tuaj yeem tshuab hauv chav tsev kub thiab tsim cov yas deformation ntawm qhov kub thiab txias.Nws tseem muaj qhov kub zoo ruaj khov thiab oxidation tsis kam. Nws kuj muaj zoo thermal poob siab tsis kam, tiv thaiv kev puas tsuaj thiab zoo tshuaj corrosion kuj.
MAX theem ceramics (suav nrog Ti3SiC2, Ti2AlC, thiab lwm yam) yog hom tshiab ntawm cov khoom siv ua muaj plooj hluavtaws. Cov ceramics no muaj ntau tshaj li rau caum ternary carbides los yog nitrides. M sawv rau pem hauv ntej hlau caij ntawm kev hloov pab pawg; A sawv cev ntawm cov pab pawg tseem ceeb, feem ntau yog cov ua ntawm pawg peb thiab pawg thib plaub; X yog rau cov pa roj carbon lossis nitrogen. Ti3SiC2 yog qhov muaj kev kawm ntau tshaj plaws. Ti3SiC2 tau ntse ua tiav los ntawm kub nias hauv 1996 los ntawm cov xibfwb Barsoum M ntawm Drexel University hauv Tebchaws Meskas thiab nws cov khoom zoo heev tau pom. Vim nws qhov tshwj xeeb nanometer fawm kib siv lead ua qauv, hom khoom zoo nkauj no muaj cov khoom xws li oxidation tsis kam, nws tus kheej lubrication, lub siab pob txha, tawv ntawm chav sov thiab kev coj ua. Cov khoom zoo li no tuaj yeem siv dav raws li cov txheej txheem kub kub, cov khoom siv txhuam hluav taws xob, cov khoom siv tshuaj tua kab mob thiab ua kom kub lub zog kub. Cov khoom lag luam yog siv rau kev kub txheej txheej, MXene ua ntej, kev coj tus kheej lubricating ceramics, lithium ion roj teeb, supercapacitors, electrochemical catalysis.
