Ceramic ya Beryllia (Beryllium Oxide, cyangwa BeO) yakozwe mu myaka ya za 1950 nk'ibikoresho byo mu kirere bya tekiniki yo mu kirere, kandi itanga ihuza ridasanzwe ry'imitungo itaboneka mu bindi bikoresho by'ubutaka. Ifite imiterere yihariye yubushyuhe, dielectric, nubukanishi, bituma yifuzwa cyane gukoreshwa mubikoresho bya elegitoroniki. Ibiranga umwihariko wibi bikoresho. BeO ceramic ifite imbaraga zisumba izindi, zidasanzwe zo gutakaza dielectric, kandi ikora ubushyuhe neza kuruta ibyuma byinshi. Itanga amashanyarazi menshi hamwe na dielectric yo hasi ihoraho hiyongereyeho Alumina nziza yumubiri na dielectric.

Nibikoresho byiza mubisabwa bisaba ubushyuhe bwinshi kimwe na dielectric na mashini kubera imbaraga zayo nziza. Birakwiriye cyane cyane gukoreshwa nka lazeri ya diode na semiconductor ubushyuhe, hamwe nuburyo bwihuse bwo kohereza ubushyuhe bwumuzunguruko muto kandi burimo ibikoresho bya elegitoroniki.
