Ngwakọta kemịkalụ
Nke mbụ, anyị kwesịrị ịkọwa na ọcha carbon ojii na silicon dioxide nwere otu ihe mejupụtara kemịkalụ, usoro kemịkalụ ha bụkwa SiO₂. White carbon ojii bụ n'ezie ụdị silica kpọmkwem, ihe mejupụtara ya nwekwara ike ịbụ SiO2 · nH2O, ebe nH2O dị n'ụdị otu hydroxyl dị n'elu.
Ọdịdị na ihe onwunwe
N'ihe gbasara ọdịdị na ihe ndị e ji mara ya, ojii ọcha na silica dịkwa iche. Ọdịdị silica bụ ntụ ọcha amorphous, ọ naghị egbu egbu, ọ naghị esi isi, ọ dịghịkwa mmetọ. Ọdịdị ya dị okirikiri, na-agbaze, ma dịkwa ka nke netwọk, ọ naghị agbaze na mmiri. N'aka nke ọzọ, ọdịdị nke ojii ọcha bụ ntụ ọcha, granular ma ọ bụ nke na-adịghị agbanwe agbanwe, ọ na-agbaze na soda caustic na hydrofluoric acid, ọ naghị agbaze na mmiri, ihe mgbaze, na asịd (ewezuga hydrofluoric acid), ma nwee njirimara nke iguzogide okpomọkụ dị elu, enweghị ike ire ọkụ, enweghị isi, enweghị isi, na ezigbo mkpuchi eletriki.

N'ihe gbasara ojiji, ojii ọcha na silica nwekwara njirimara nke ha. Silicon dioxide bụ ihe dị mkpa eji emepụta iko, iko quartz, sodium silicate, eriri optical, ihe ndị dị mkpa nke ụlọ ọrụ eletrọnịkị, ngwa anya, ọrụ aka, na ihe ndị na-adịghị mma. A na-ejikarị ojii ọcha na ngwaahịa rọba, kemịkalụ ugbo, ngwaahịa kemịkalụ kwa ụbọchị, plastik, mkpuchi, ihe mejupụtara resin, na ihe na-ejupụta akwụkwọ. Na mgbakwunye, ejirila ojii ọcha na-acha ọcha dị ka ihe nnọchi anya carbon ojii na ngwaahịa rọba.
Ụzọ nkwadebe
Maka usoro nkwadebe, ojii ọcha nke carbon na silica dịkwa iche. Enwere ike ịkwadebe ojii ọcha nke carbon site na usoro mmiri ozuzo ma ọ bụ usoro gas, ụzọ nkwadebe dị iche iche na-ebute ngwaahịa abụọ dị iche iche nwere otu usoro molekul.
Àgwà arụmọrụ
N'ihe gbasara njirimara arụmọrụ, enwerekwa ọdịiche dị n'etiti ojii ọcha na carbon na silica. Black carbon ojii bụ ihe nwere oghere, nwere nhazi na obere nhazi yiri nke carbon ojii. N'aka nke ọzọ, Nano silica bụ ihe ọcha na-abụghị nke na-egbu egbu, na-enweghị isi, na nke na-enweghị mmetọ, nke nwere obere nha (0-100nm) na nnukwu mpaghara elu kpọmkwem. O nwere njirimara ntụgharị uche siri ike nke ukwuu maka ultraviolet, infrared, na ìhè a na-ahụ anya. Mmetụta olu na mmetụta ọwara quantum nke nano silica na-eme ka ọ nwee mmetụta percolation, nke nwere ike ịmepụta nhazi netwọk oghere yana ngwakọta molekul organic, na-eme ka ike igwe, ike, nguzogide iyi, na nguzogide ịka nká nke ihe polymer dịkwuo mma.
Na nchịkọta, ọ bụ ezie na ojii carbon ọcha na silica nwere otu ihe mejupụtara kemịkalụ, ha dị iche na ọdịdị, ihe onwunwe, ebe a na-eji ya, na ụzọ nkwadebe.
