Hakowa darajar cenosphere
Cenosphere wani nau'i ne mai nauyi, mara nauyi, mara sarari wanda aka yi shi da silica da alumina kuma an cika shi da iska ko iskar gas, yawanci ana samar da shi azaman sakamakon konewar kwal a masana'antar wutar lantarki.Launin cenospheres ya bambanta daga launin toka zuwa kusan fari kuma yawansu ya kai kusan 0.35-0.45g/cc, wanda ke ba su babban buoyancy.Cf.gilashin microspheres.
