Qodista darajada cenosphere
Cenosphere waa meel fudfudud, qallafsan, bannaan oo bannaan oo inta badan silica iyo alumina ka samaysan oo ay ka buuxaan hawo ama gaas aan shaqaynayn, oo caadi ahaan loo soo saaro wax-soo-saarka dhuxusha ee dhirta tamarta kulaylka ah.Midabka cenospheres wuu ku kala duwan yahay cawl ilaa cad cad cufnaantooduna waa qiyaastii 0.35-0.45g/cc, taas oo siinaysa xamaasad weyn.Cf.mikrospheres galaas.

ASTAAMAHA:
Cenospheres waa adag yihiin oo adag, iftiin, biyuhu ma-macaan, aan waxyeello lahayn, iyo dahaarka.Tani waxay ka dhigaysaa inay aad uga faa'iidaystaan alaabooyin kala duwan, gaar ahaan kuwa buuxinaya.Cenospheres hadda waxaa loo isticmaalaa buuxinta sibidhka si loo soo saaro shubka cufnaanta hoose.Dhawaan, qaar ka mid ah soosaarayaasha ayaa bilaabay buuxinta biraha iyo polymers-ka cenospheres si ay u sameeyaan walxo isku dhafan oo khafiif ah oo ka xoog badan noocyada kale ee alaabta xumbo.Qalabka isku dhafan ee noocan oo kale ah waxaa loo yaqaan xumbo syntactic.Xumbo syntactic-ku-salaysan aluminium ayaa ka helaya codsiyada qaybta baabuurta.
Cenospheres-ka dahaarka leh ee qalinka ah ayaa loo adeegsadaa dahaarka korantada, tiirarka iyo maryaha.Isticmaalka kale waa in rinji conductive for daahan antistatic iyo gaashaanka electromagnetic.
ISTICMAALKA:
1.Dhismaha ( darbiyada gidaarka, looxa fiber la taaban karo, buuxinta alwaax)
2. Dahaarka (wadda weyn, tuubooyinka goglan, waddooyinka)
3.Gawaadhida (cadaynta codka, suufka biriiga, dahaarka hoostooda)
4. Madadaalada (sabaynta, looxyada dabaasha, qalabka golfka, iwm.)
5. Ceramics (tuug, bulukeeti, sibidh heerkul sarreeya, iwm.)
6.Garoonka saliidda (dhoobo qodista, sibidhka)
7. Caagagga (PVC, isku-darka, filim)
8.Aerospace (dahaarka dhoobada, iwm)
