Izakhiwo ezinhle kakhulu kanye nokusetshenziswa kwe ama-cenospheres: ukuphikiswa okuphezulu. Izakhi eziyinhloko zamakhemikhali ama-cenospheres ama-oxide e-silicon ne-aluminium, lapho i-silicon dioxide ingama-50-65%, kanti i-aluminium oxide ingama-25-35%. Ngenxa yokuthi iphuzu lokuncibilika kwe-silica liphezulu njengo-1725 degrees Celsius, iphuzu lokuncibilika kwe-aluminium oxide lingama-2050 degrees Celsius, zombili ziphezulu. izinto eziphikisayoNgakho-ke, ama-cenospheres anokumelana okuphezulu kakhulu, ngokuvamile afinyelela kuma-degree Celsius angu-1600-1700, okwenza abe yinto enhle kakhulu ephikisanayo esebenza kahle kakhulu. Ukuvimbela ukushisa okulula. Udonga lwama-cenospheres luncane futhi lugobile, kanti umgodi u-semi-vacuum, unegesi elincane kakhulu (i-N2, i-H2 ne-CO2, njll.), futhi ukuhanjiswa kokushisa kuhamba kancane kakhulu futhi kuncane kakhulu. Ngakho-ke, ama-cenospheres awagcini nje ngokuba nesisindo esincane (ubuningi obungu-250-450 kg/m3), kodwa futhi angcono kakhulu ekuvimbeleni ukushisa (ukuqhuba ukushisa ekushiseni kwegumbi okungu-0.08-0.1), okubeka isisekelo sokuba abonise amakhono awo emkhakheni wezinto zokuvimbela ukushisa ezilula. Ubulukhuni namandla aphezulu. Ngenxa yokuthi ama-cenospheres ayimizimba yengilazi eqinile eyakhiwe yizigaba zamaminerali ze-silicon aluminium oxide (i-quartz ne-mullite), ubulukhuni bungafinyelela ezingeni lika-Mohs 6-7, amandla okucindezela okungaguquki aphezulu njengo-70-140MPa, kanti ubukhulu bangempela bungu-2.10-2.20 g/cm3. bufana nedwala. Ngakho-ke, ama-cenospheres anamandla aphezulu. Ngokuvamile, izinto ezilula ezinezimbobo noma ezingenalutho njenge-perlite, i-zeolite, i-diatomite, i-pumice, i-vermiculite enwetshiwe, njll. zinobulukhuni namandla aphansi, kanti imikhiqizo yokushisa noma imikhiqizo elula yokungaguquguquki eyenziwe ngazo inamandla okungekuhle. Ukushiyeka kwazo kuyinzuzo yama-cenospheres, ngakho-ke ama-cenospheres anezinzuzo zokuncintisana kakhulu kanye nokusetshenziswa okubanzi. Usayizi wezinhlayiya ezincane kanye nendawo enkulu ethile. Usayizi wezinhlayiya zama-beads akhiwe ngokwemvelo ungama-microns angu-1-250. Indawo ethile yendawo ingu-300-360cm2/g, efana nesamente. Ngakho-ke, ama-cenospheres angasetshenziswa ngqo ngaphandle kokugaya. Ubuncane bungahlangabezana nezidingo zemikhiqizo ehlukahlukene. Ezinye izinto zokuvikela ukushisa ezilula ngokuvamile zinezinhlayiya ezinkulu (njenge-perlite, njll.). Uma zigayiwe, umthamo uzokwanda kakhulu, futhi ukuvikela ukushisa kuzoncishiswa kakhulu. Kulokhu, ama-cenospheres anenzuzo. Ukuvikela kagesi okuhle kakhulu. Ama-cenospheres, ngemva kokukhethwa kwama-magnetic beads, ayizinto zokuvikela ukushisa ezinhle kakhulu futhi azihambisani nokushisa. Ngokuvamile, ukumelana kwama-insulator kunciphisa ngokwanda kwezinga lokushisa, kodwa ukumelana kwama-cenospheres kuyanda ngokwanda kwezinga lokushisa. Le nzuzo ayitholakali ngezinye izinto zokuvikela ukushisa. Ngakho-ke, ingenza imikhiqizo yokuvikela ukushisa ngaphansi kwezimo zokushisa eziphakeme.
