Cov txheej txheem ntau lawm ntawm silicon nitride yog raws li hauv qab no: ntawm 1300 ～ 1400 ℃, hmoov silicon yog reacted nrog nitrogen; ntawm 1500 ℃, ntshiab silicon yog hnov mob nrog ammonia;
Hlawv qhov sib xyaw ua ke ntawm silica thiab carbon hauv nitrogen uas muaj me me ntawm hydrogen; cov khoom lag luam aminolysis Si (NH2) 4 ntawm SiCl4 yog qhov ua kom sov tag. Silicon nitride tuaj yeem raug siv los ua cov cab hluav taws xob hauv lub cev, cov khoom siv tiv thaiv kub, tshuaj pleev xim rau thiab txhim kho. Silicon nitride ceramics muaj cov yam ntxwv ntawm siab zog thiab siab kub kuj.
Ntawm cov khoom siv ceramic, lawv muaj cov khoom siv zoo tshaj plaws txhua yam, thermal shock tsis kam, oxidation tsis kam, hnav tsis kam thiab corrosion kuj. Ib tus neeg sib tw cov khoom siv. Hauv kev siv tshuab kev lag luam, silicon nitride ceramics yog siv los ua cov khoom npas, yob, lub pob sib tw, cov cuab yeej thiab cov pwm, cov cuab yeej tshiab ceramic, twj tso kua mis, thiab ntxaiv foob cov ntaub ntawv. Hauv kev lag luam chemical, silicon nitride ceramics yog siv coj los ua kev hnav-kev tiv thaiv thiab kev txhim kho tiv thaiv kev ua lag luam. Xws li cov pob, cov twj tso kua mis lub cev, kev sib txuas ntawm cov nqus pa, lim dej, thiab lwm yam.
