ʻO ka cenosphere papa wili
ʻO Cenosphere kahi pōʻai māmā, inert, hollow i hana nui ʻia me ka silica a me ka alumina a hoʻopiha ʻia me ka ea a i ʻole ke kinoea inert, i hana pinepine ʻia ma ke ʻano he hopena o ka puhi lanahu ma nā mea kanu wela.ʻOkoʻa ka waihoʻoluʻu o nā cenospheres mai ka hina a kokoke i keʻokeʻo a ʻo ko lākou nui ma kahi o 0.35-0.45g/cc, e hāʻawi iā lākou i ka buoyancy nui.Cf.aniani microspheres.

HIʻO:
He paʻakikī a ʻoʻoleʻa nā Cenospheres, māmā, wai ʻole, ʻinoʻino, a insulative.Hoʻohana nui kēia iā lākou i nā huahana like ʻole, ʻoi aku ka hoʻopiha piha.Hoʻohana ʻia nā Cenospheres ma ke ʻano he mea hoʻopiha i ka sima no ka hana ʻana i ke koki haʻahaʻa haʻahaʻa.I kēia mau lā, ua hoʻomaka kekahi mau mea hana e hoʻopiha i nā metala a me nā polymers me nā cenospheres e hana i nā mea hana composite māmā me ka ikaika kiʻekiʻe ma mua o nā ʻano mea ʻē aʻe.Ua kapa ʻia kēlā mau mea hoʻohuihui syntactic foam.Ke ʻimi nei nā ʻōhua syntactic kumu alumini i nā noi ma ka ʻāpana kaʻa.
Hoʻohana ʻia nā cenospheres i hoʻopaʻa ʻia i ke kala i nā pale conductive, nā tile a me nā lole.ʻO kahi hoʻohana ʻē aʻe i loko o nā pena conductive no nā uhi antistatic a me ka pale electromagnetic.
Hoʻohana:
1.Construction (pā pā, papa fiber concret, hoʻopiha lāʻau)
2. Coatings (alanui, undergound paipu, ala kaʻa)
3.Automotive (ka hoʻopaʻa leo, nā pale pale, lalo o ka uhi)
4. Nā leʻaleʻa (flotation, papa heʻe nalu, nā mea kolepa, etc.)
5.Ceramics (tiles, firebricks, high temperature cement, etc.)
6. ʻO ka ʻaila ʻaila (wili ʻalae, hoʻopaʻa ʻana)
7.Plastics (PVC, hoʻohuihui, kiʻiʻoniʻoni)
8.Aerospace (ka insulation ceramic, etc.)
