El óxido de berilio se emplea para la fabricación de crisoles, en pastas refractarias especiales, dada sus buenas aptitudes para aguantar el choque térmico a elevadas temperaturas. Es usado en la formulación de las porcelanas modernas.
Es altamente tóxico, aunque el óxido es de todos los compuestos de berilio el menos tóxico.
