Ibigize ibinyabutabire by’ingenzi mu masharubu areremba ni okiside ya silikoni na aluminiyumu, aho ingano ya silikoni diokiside iri hagati ya 50-65%, naho ingano ya aluminiyumu okiside iri hagati ya 25-35%. Kubera ko aho silika ishongera iri hejuru ya 1725 ℃ naho iya alumina ikaba 2050 ℃, byose ni ibikoresho birenza urugero. Kubwibyo, amasharubu areremba afite ubushobozi bwo kurenza urugero cyane, muri rusange agera kuri 1600-1700 ℃, bigatuma aba meza cyane mu kurerenza urugero. Uburemere bworoheje, ubushyuhe butuma amashanyarazi ashyuha. Urukuta rw'amasharubu areremba ni rugufi kandi rufite ubujyakuzimu, aho umwobo ni semi vacuum, ni gaze nto cyane (N2, H2 na CO2, nibindi), kandi ubushyuhe bugenda buhoro cyane kandi ni buto cyane. Kubwibyo, amasaro areremba ntabwo ari yoroshye gusa mu buremere (uburemere 250-450 kg / m3), ahubwo anafite ubushobozi bwo gukingira ubushyuhe (gutwara ubushyuhe 0.08-0.1 ku bushyuhe bw'icyumba), ibi bikaba ari byo bishyiraho urufatiro kugira ngo agire uruhare runini mu bijyanye n'ibikoresho byo gukingira ubushyuhe byoroheje.

Ubukana n'imbaraga nyinshi. Kubera ko agasaro k'amazi ari umubiri w'ikirahure gikomeye wakozwe na silica alumina mineral phase (quartz na mullite), ubukana bwako bushobora kugera kuri Mohs 6-7, imbaraga z'umuvuduko udahinduka zishobora kugera kuri 70-140mpa, kandi ubucucike bwako nyakuri ni 2.10-2.20g / cm3, bingana n'ubw'amabuye. Kubwibyo, amasaro areremba afite imbaraga nyinshi. Muri rusange, ibikoresho bifite imyenge yoroheje cyangwa ibidafite aho bibohera nka perlite, ibuye ribira, diatomite, sepiolite na vermiculite yagutse bifite ubukana n'imbaraga nke. Ibikoresho bikingira ubushyuhe cyangwa ibikoresho bigabanya urumuri bikozwe muri byo bifite ingaruka mbi zo kuba imbaraga nke. Intege nke zabyo ni imbaraga z'amasaro areremba gusa, bityo amasaro areremba afite inyungu nyinshi kandi akoreshwa mu buryo bwagutse. Ingano y'uduce ni nziza kandi ubuso bwihariye ni bunini. Ingano karemano y'amasaro areremba ni 1-250 μ M. Ubuso bwihariye ni 300-360cm2 / g, nk'ubwa sima. Kubwibyo, amasaro areremba ashobora gukoreshwa mu buryo butaziguye nta gusya.

Ubuto bushobora guhaza ibyo ukeneye mu bicuruzwa bitandukanye, ibindi bikoresho byoroshye byo gukingira ubushyuhe muri rusange ni uduce duto (nka perlite, nibindi), niba gusya byongera cyane ubushobozi, ku buryo gukingira ubushyuhe bigabanuka cyane. Muri urwo rwego, amasaro areremba afite ibyiza. Gukingira amashanyarazi neza cyane. Amasaro areremba ni ibikoresho byiza byo gukingira ubushyuhe kandi ntibitwara amazi. Muri rusange, ubushobozi bwo kwirinda bugabanuka uko ubushyuhe bwiyongera, ariko ubushobozi bwo kwirinda bugabanuka uko ubushyuhe bwiyongera. Iyi nyungu ntabwo iri mu bindi bikoresho byo gukingira ubushyuhe. Kubwibyo, ishobora gukora ibikoresho byo gukingira ubushyuhe mu gihe cy'ubushyuhe bwinshi.
