Izakhiwo ezinhle kakhulu kanye nokusetshenziswa kweama-cenospheres : i-refractoriness ephezulu. Izingxenye zamakhemikhali eziyinhloko zeama-cenospheres ama-oxide e-silicon ne-aluminium, lapho i-silicon dioxide icishe ibe ngu-50-65%, futhi i-aluminium oxide icishe ibe ngu-25-35%. Ngenxa yokuthi izinga lokuncibilika kwe-silica liphakeme ngo-1725 degrees Celsius, indawo yokuncibilika ye-aluminium oxide ingu-2050 degrees Celsius, womabili aphakeme.izinto eziphikisayo . Ngakho-ke, ama-cenospheres ane-refractoriness ephezulu kakhulu, ngokuvamile afinyelela ku-1600-1700 degrees Celsius, okuwenza abe yimpahla esebenza kahle kakhulu ephikisayo. I-lightweight, i-thermal insulation. Udonga lwama-cenospheres luncane futhi luyizigodi, futhi i-cavity iyi-semi-vacuum, inenani elincane kakhulu legesi (N2, H2 kanye ne-CO2, njll.), futhi ukuqhutshwa kokushisa kuhamba kancane kakhulu futhi kuncane kakhulu. Ngakho-ke, ama-cenospheres awagcini nje ngokukhanya ngesisindo (ubuningi bobuningi 250-450 kg/m3), kodwa futhi ahle kakhulu ekushiseni okushisayo (i-thermal conductivity ekamelweni lokushisa 0.08-0.1), okubeka isisekelo sokuba babonise amakhono abo ensimini. wezinto zokufakwa ezishisayo ezingasindi. Ubulukhuni obuphezulu namandla. Ngenxa yokuthi amacenosphere ayimizimba yengilazi eqinile eyakhiwe izigaba zamaminerali e-silicon aluminium oxide (i-quartz ne-mullite), ubulukhuni bungafinyelela ezingeni le-Mohs 6-7, amandla okucindezela okumile afinyelela ku-70-140MPa, kanti ukuminyana kweqiniso kungu-2.10-2.20 g/cm3. kuqhathaniswa nedwala. Ngakho-ke, ama-cenospheres anamandla aphezulu. Imvamisa, izinto ezingasindi ezinezimbobo noma ezingenalutho ezifana ne-perlite, i-zeolite, i-diatomite, i-pumice, i-vermiculite enwetshiwe, njll. zinobulukhuni obumpofu namandla, kanye nemikhiqizo yokufakwa kwe-thermal noma imikhiqizo ephikisayo engasindi eyenziwe ngayo inokungalungi kahle kwamandla. Ukushiyeka kwabo kuyinzuzo ye-cenospheres, ngakho-ke ama-cenospheres anezinzuzo ezincintisanayo kanye nokusetshenziswa okubanzi. Usayizi wezinhlayiya ezinhle kanye nendawo enkulu ethize. Usayizi wezinhlayiyana zobuhlalu obakhiwe ngokwemvelo yi-1-250 microns. Indawo ethize ingu-300-360cm2/g, efana nosimende. Ngakho-ke, ama-cenospheres angasetshenziswa ngokuqondile ngaphandle kokugaya. I-fineness ingahlangabezana nezidingo zemikhiqizo ehlukahlukene. Ezinye izinto zokuvikela ezishisayo ezingasindi zivame ukuba nosayizi abakhulu bezinhlayiyana (njenge-perlite, njll.). Uma ziphansi, umthamo uzokwandiswa kakhulu, futhi ukufakwa kwe-thermal kuzoncishiswa kakhulu. Kulokhu, ama-cenospheres anenzuzo. I-insulation kagesi enhle kakhulu. I-Cenospheres, ngemva kokukhethwa kobuhlalu kazibuthe, iyizinto ezinhle kakhulu zokuvikela futhi ezingezona eziqhutshwayo. Ngokuvamile, ukumelana kwama-insulators kuncipha ngokunyuka kwezinga lokushisa, kodwa ukumelana kwama-cenospheres kuyanda ngokunyuka kwezinga lokushisa. Le nzuzo ayitholakali nezinye izinto zokuvikela. Ngakho-ke, ingenza imikhiqizo yokushisa ngaphansi kwezimo zokushisa eziphezulu.
