Thepa e babatsehang le tšebeliso eacenospheres : refractoriness e phahameng. Likarolo tse kholo tsa lik'hemik'hale tsacenospheres Ke li-oxide tsa silicon le aluminium, tseo silicon dioxide e ka bang 50-65%, le aluminium oxide e ka bang 25-35%. Hobane sebaka se qhibilihang sa silica se ka holimo ho likhato tse 1725 tsa Celsius, sebaka se qhibilihang sa aluminium oxide ke likhato tse 2050 tsa Celsius, tseo ka bobeli li leng holimo.lisebelisoa tsa refractory . Ka hona, li-cenospheres li na le refractoriness e phahameng haholo, hangata e fihla ho likhato tse 1600-1700 tsa Celsius, e leng se etsang hore e be lisebelisoa tse sebetsang hantle tse sebetsang hantle haholo. E bobebe, e futhumatsang mocheso. Lerako la cenospheres le tšesaane ebile le le sekoti, 'me sekoti ke semi-vacuum, se nang le khase e nyenyane haholo (N2, H2 le CO2, joalo-joalo),' me mocheso oa mocheso o lieha haholo ebile o monyenyane haholo. Ka hona, li-cenospheres ha li bobebe feela ka boima ba 'mele (boima bo bongata ba 250-450 kg / m3), empa hape li ntle haholo ka ho kenya mocheso oa mocheso (mocheso oa mocheso oa mocheso oa 0.08-0.1), o behang motheo oa ho bontša litalenta tsa bona tšimong. ea lisebelisoa tse bobebe tse futhumatsang mocheso. Boima bo phahameng le matla. Hobane li-cenospheres ke lihlopha tsa khalase tse thata tse entsoeng ke silicon aluminium oxide mineral phases (quartz le mullite), boima bo ka fihla boemong ba Mohs 6-7, matla a khatello ea static a phahame ho 70-140MPa, 'me boima ba' nete ke 2.10-2.20 g/cm3. e bapisoang le lefika. Ka hona, li-cenospheres li na le matla a phahameng. Ka kakaretso, lisebelisoa tse bobebe tsa porous kapa tse se nang letho tse kang perlite, zeolite, diatomite, pumice, vermiculite e atolositsoeng, joalo-joalo li na le bothata bo fokolang le matla, 'me lihlahisoa tsa ho kenya mocheso kapa lihlahisoa tse bobebe tse entsoeng ka tsona li na le mefokolo e fokolang. Mefokolo ea bona ke hantle melemo ea cenospheres, kahoo cenospheres e na le melemo ea tlholisano le ts'ebeliso e pharaletseng. Boholo bo botle ba likaroloana le sebaka se seholo se ikhethileng. Boholo ba likaroloana tsa lifaha tse entsoeng ka tlhaho ke 1-250 microns. Sebaka se khethehileng sa sebaka ke 300-360cm2 / g, se tšoanang le samente. Ka hona, li-cenospheres li ka sebelisoa ka ho toba ntle le ho sila. The fineness ka finyella litlhoko tsa lihlahisoa tse sa tšoaneng. Lisebelisoa tse ling tse bobebe tsa ho futhumatsa mocheso hangata li na le boholo ba likaroloana tse kholo (joalo ka perlite, jj.). Haeba li le fatše, matla a tla eketseha haholo, 'me mocheso oa mocheso o tla fokotseha haholo. Tabeng ena, li-cenospheres li na le molemo. Motlakase o motle ka ho fetisisa. Li-cenospheres, ka mor'a hore ho khethoe likhahla tsa makenete, ke lisebelisoa tse ntle tsa ho sireletsa le tse sa sebetseng. Ka kakaretso, ho hanyetsa ha li-insulators ho fokotseha ka ho eketseha ha mocheso, empa khanyetso ea cenospheres e eketseha ka ho eketseha ha mocheso. Molemo ona ha o fumanehe ka lisebelisoa tse ling tsa insulating. Ka hona, e ka etsa lihlahisoa tsa insulating tlas'a maemo a phahameng a mocheso.
