Beryllia ceramic (Beryllium Oxide, los yog BeO) tau tsim nyob rau hauv 1950s raws li lub hnub nyoog ntawm cov khoom siv ceramic, thiab nws muaj kev sib xyaw tshwj xeeb ntawm cov khoom tsis pom nyob rau hauv lwm yam khoom siv ceramic. Nws muaj kev sib xyaw tshwj xeeb ntawm thermal, dielectric, thiab cov khoom siv kho tshuab, ua rau nws xav tau siv rau hauv cov ntawv thov hluav taws xob. Cov yam ntxwv no tshwj xeeb rau cov khoom siv no. BeO ceramic muaj lub zog zoo dua, tshwj xeeb tshaj yog tsis tshua muaj dielectric poob cov yam ntxwv, thiab ua kom sov zoo dua li cov hlau feem ntau. Nws muaj ntau dua thermal conductivity thiab qis dielectric tas li ntxiv rau Alumina lub cev zoo thiab dielectric zog.

Nws yog ib qho khoom siv zoo tshaj plaws rau cov ntawv thov uas yuav tsum tau muaj cua sov dissipation nrog rau dielectric thiab mechanical zog vim nws cov thermal conductivity zoo heev. Nws yog qhov tshwj xeeb tshaj yog tsim nyog rau kev siv raws li diode laser thiab semiconductor tshav kub dab dej, nrog rau cov thermal hloov ceev ceev rau cov khoom siv hluav taws xob me me thiab cov khoom siv hluav taws xob nruj.
