Si3N4 tau lees paub tias yog cov khoom siv zoo tshaj plaws ceramic substrate nrog cov thermal conductivity thiab kev ntseeg siab hauv tsev thiab txawv teb chaws. Txawm hais tias lub thermal conductivity ntawm Si3N4 ceramic substrate yog me ntsis qis dua li ntawm AlN, nws lub zog flexural thiab tawg toughness tuaj yeem ncav cuag ntau tshaj ob npaug ntawm AlN. Lub caij no, cov thermal conductivity ntawm Si3N4 ceramic yog ntau dua li ntawm Al2O3 c

Txij li thaum xyoo pua 21st, bulletproof ceramics tau tsim sai nrog ntau hom, suav nrog Alumina, Silicon Carbide, Boron carbide, silicon Nitride, Titanium Boride, thiab lwm yam. Ntawm lawv, Alumina Ceramics (Al2O3), Silicon Carbide ceramics (SiC) thiab Boron Carbide Ceramics. (B4C) yog cov siv dav tshaj plaws.
