Ngwongwo mara mma na ojiji nke cenospheres.

Magburu onwe Njirimara na ojiji nkecenospheres : elu refractoriness. Isi chemical components nkecenospheres bụ oxides nke silicon na aluminom, nke silicon dioxide bụ ihe dịka 50-65%, na aluminum oxide bụ ihe dịka 25-35%. N'ihi na ebe mgbaze nke silica dị elu dị ka 1725 degrees Celsius, ebe mgbaze nke aluminum oxide bụ 2050 degrees Celsius, nke abụọ dị elu.ihe refractory . Ya mere, cenospheres nwere oke refractoriness, na-erute 1600-1700 degrees Celsius, na-eme ka ha bụrụ ihe magburu onwe elu-arụmọrụ refractory ihe. Dị arọ, mkpuchi ọkụ. Mgbidi nke cenospheres dị gịrịgịrị na oghere, oghere ahụ dịkwa obere oghere, nwere naanị obere gas (N2, H2 na CO2, wdg), na njikwa okpomọkụ dị oke nwayọ ma dịkwa obere. Ya mere, cenospheres abụghị naanị ìhè na ịdị arọ (nnukwu njupụta 250-450 kg / m3), kamakwa magburu onwe ya na mkpuchi ọkụ (thermal conductivity na ụlọ okpomọkụ 0.08-0.1), nke na-atọ ntọala maka ha iji gosipụta talent ha n'ọhịa. nke ihe mkpuchi thermal dị arọ. Isi ike na ike dị elu. N'ihi na cenospheres bụ ozu iko siri ike nke silicon aluminom oxide mineral kpụrụ (quartz na mullite), siri ike nwere ike iru ọkwa Mohs 6-7, ike nrụgide static dị elu dị ka 70-140MPa, na ezigbo njupụta bụ 2.10-2.20. g/cm3. tụnyere nkume.
