Berilijum-oksid je neorgansko hemijsko jedinjenje čija je hemijska formula BeO.

Osobine uredi

Berilijum-oksid je beo, nerastvoran prah. Sa kiselinama gradi berilijumove soli, koje su po osobinama slične magnezijumovim. Reaguje i sa rastvorima alkalnih hidroksida. U reakciji sa kalijum-hidroksidom gradi K₂BeO₄.^[4]

Osobina	Vrednost
Particioni koeficijent^[5] (ALogP)	-0,0
Rastvorljivost^[6] (logS, log(mol/L))	0,9
Polarna površina^[7] (PSA, Å²)	17,1

Dobijanje uredi

Može se dobiti žarenjem metala ili nitrata na vazduhu, ali se najčešće dobija iz berila.^[4]
