Iimpawu ezintle kunye nokusetyenziswa kwe ii-cenospheres: ukunganyangeki okuphezulu. Iinxalenye eziphambili zeekhemikhali ze ii-cenospheres zii-oxide ze-silicon kunye ne-aluminium, apho i-silicon dioxide imalunga ne-50-65%, kwaye i-aluminium oxide imalunga ne-25-35%. Ngenxa yokuba iqondo lokunyibilika kwe-silica liphezulu njenge-1725 degrees Celsius, iqondo lokunyibilika kwe-aluminium oxide lingama-2050 degrees Celsius, zombini ezi ziphezulu. izixhobo ezichasayo. Ke ngoko, ii-cenospheres zinamandla aphezulu kakhulu okuchasana, ngokubanzi zifikelela kwi-1600-1700 degrees Celsius, nto leyo eyenza zibe zizinto ezichasana nokusebenza kakuhle. Zilula kwaye zigqunywe ngobushushu. Udonga lwee-cenospheres lubhityile kwaye lungenanto, kwaye umngxuma ulu-semi-vacuum, unomlinganiselo omncinci kakhulu wegesi (i-N2, i-H2 kunye ne-CO2, njl.njl.), kwaye ukuhanjiswa kobushushu kuhamba kancinci kakhulu kwaye kuncinci kakhulu. Ke ngoko, ii-cenospheres azilula nje kuphela ngobunzima (ubuninzi obuyi-250-450 kg/m3), kodwa zikwabalaseleyo kwi-thermal insulation (ukuqhuba kobushushu kubushushu begumbi obuyi-0.08-0.1), nto leyo ebeka isiseko sokuba zibonise italente yazo kwicandelo lezixhobo zokukhusela ubushushu ezikhaphukhaphu. Ubunzima namandla aphezulu. Ngenxa yokuba ii-cenospheres ziyimizimba yeglasi eqinileyo eyenziwe zii-silicon aluminum oxide mineral phases (quartz kunye ne-mullite), ubunzima bunokufikelela kwinqanaba le-Mohs 6-7, amandla oxinzelelo oluzinzileyo aphezulu njenge-70-140MPa, kwaye uxinano lokwenyani yi-2.10-2.20 g/cm3. Zifana nelitye. Ke ngoko, ii-cenospheres zinamandla aphezulu. Ngokubanzi, izinto ezikhaphukhaphu okanye ezingenanto ezifana ne-perlite, i-zeolite, i-diatomite, i-pumice, i-vermiculite eyandisiweyo, njl. zinobunzima obuphantsi kunye namandla, kwaye iimveliso zokuthintela ubushushu okanye iimveliso ezikhaphukhaphu ezenziwe ngazo zinamandla aphantsi. Ukusilela kwazo zizinto ezilungileyo ze-cenospheres, ngoko ke ii-cenospheres zineengenelo zokukhuphisana ngakumbi kunye nokusetyenziswa okubanzi. Ubungakanani be-particle entle kunye nommandla omkhulu womphezulu othile. Ubungakanani be-particle yee-beads ezenziwe ngokwemvelo yi-1-250 microns. Ummandla othile womphezulu yi-300-360cm2/g, efana nesamente. Ke ngoko, ii-cenospheres zingasetyenziswa ngokuthe ngqo ngaphandle kokusila. Ubunono bunokuhlangabezana neemfuno zeemveliso ezahlukeneyo. Ezinye izinto zokukhusela ubushushu ezilula zihlala zineziqwenga ezinkulu (ezifana ne-perlite, njl.njl.). Ukuba zigayiwe, umthamo uya kwanda kakhulu, kwaye ukhuseleko lobushushu luya kuncitshiswa kakhulu. Kule meko, ii-cenospheres zinenzuzo. Ukhuseleko lombane oluhle kakhulu. Ii-cenospheres, emva kokuba kukhethwe iintsimbi zemagnethi, zizinto ezikhuselayo ezibalaseleyo kwaye azihambisi moya. Ngokubanzi, ukumelana kwee-insulators kuyehla ngokunyuka kobushushu, kodwa ukumelana kwee-cenospheres kuyanda ngokunyuka kobushushu. Le nzuzo ayifumaneki kwezinye izinto zokukhusela. Ke ngoko, inokwenza iimveliso zokukhusela phantsi kweemeko zobushushu obuphezulu.
