Imiterere myiza n'imikoreshereze myiza ya imiyoboro y'ikirere: ubushobozi bwo kutagira imbaraga nyinshi. Ibice by'ingenzi bya shimi imiyoboro y'ikirere ni okiside za silikoni na aluminiyumu, muri zo harimo diokiside ya silikoni iri hagati ya 50-65%, naho okiside ya aluminiyumu iri hagati ya 25-35%. Kubera ko ubushyuhe bwa silikoni bugera kuri dogere selisiyusi 1725, ubushyuhe bwa okiside ya aluminiyumu ni dogere selisiyusi 2050, byombi bikaba biri hejuru cyane. ibikoresho birwanya. Kubwibyo, cenospheres zifite ubushobozi bwo kugabanya ubushyuhe bwinshi cyane, muri rusange zigera kuri dogere selisiyusi 1600-1700, bigatuma ziba ibikoresho byiza cyane byo kugabanya ubushyuhe. Ifite ubushobozi bwo gukingira ubushyuhe bworoheje. Urukuta rw'icenospheres ni rugufi kandi rufite ubugari, kandi umwobo ni muto cyane, ufite gaze nke cyane (N2, H2 na CO2, nibindi), kandi uburyo ubushyuhe bugenda buhoro cyane kandi ni buto cyane. Kubwibyo, cenospheres ntabwo ari ibiro byoroshye gusa (ubucucike bungana na 250-450 kg/m3), ahubwo zinafite ubushobozi bwo gukingira ubushyuhe (gukwirakwiza ubushyuhe ku bushyuhe bw'icyumba 0.08-0.1), ibi bikaba ari byo bishyiraho urufatiro rwo kwerekana impano zazo mu bijyanye n'ibikoresho byo gukingira ubushyuhe byoroheje. Ubukana n'imbaraga byinshi. Kubera ko cenospheres ari ibirahure bikomeye bigizwe n'ibice by'ubutare bya silikoni aluminum oxide (quartz na mullite), ubukana bushobora kugera ku rwego rwa Mohs 6-7, imbaraga z'umuvuduko uhoraho zigera kuri 70-140MPa, kandi ubucucike nyakuri ni 2.10-2.20 g/cm3. Bigereranywa n'amabuye. Kubwibyo, cenospheres zifite imbaraga nyinshi. Muri rusange, ibikoresho byoroheje bifite imyenge cyangwa ubucucike nka perlite, zeolite, diatomite, pumice, vermiculite yagutse, nibindi bifite ubukana n'imbaraga nke, kandi ibikoresho byo gukingira ubushyuhe cyangwa ibikoresho byoroshye bikozwemo bifite imbaraga nke. Intege nke zabyo ni zo nziza za cenospheres, bityo cenospheres zifite inyungu zo guhangana kandi zikoreshwa mu buryo bwagutse. Ingano nto y'uduce duto n'ubuso bunini bwihariye. Ingano y'uduce tw'amasaro akozwe mu buryo busanzwe ni mikoroni 1-250. Ubuso bwihariye ni 300-360cm2/g, bisa na sima. Kubwibyo, cenospheres zishobora gukoreshwa neza nta gusya. Ubunini bushobora guhaza ibyifuzo by'ibicuruzwa bitandukanye. Ibindi bikoresho byoroshye byo gukingira ubushyuhe muri rusange bigira uduce duto (nka perlite, nibindi). Iyo bikozwe hasi, ubushobozi bwabyo buziyongera cyane, kandi ubushyuhe buzagabanuka cyane. Muri urwo rwego, cenospheres zifite akarusho. Ubushyuhe bwiza cyane bw'amashanyarazi. Cenospheres, nyuma yo gutoranywamo amasaro ya rukuruzi, ni ibikoresho byiza byo gukingira ubushyuhe kandi ntibitwara amashanyarazi. Muri rusange, ubushyuhe bw'ibyuma bikingira ubushyuhe buragabanuka uko ubushyuhe bwiyongera, ariko ubushyuhe bw'ibyuma bikingira burushaho kwiyongera uko ubushyuhe bwiyongera. Iyi nyungu ntabwo iboneka ku bindi bikoresho bikingira ubushyuhe. Kubwibyo, ishobora gukora ibikoresho bikingira ubushyuhe mu gihe cy'ubushyuhe bwinshi.
