Akụkụ bụ isi nke diatomite dị ka onye na-ebu bụ SiO2. Dịka ọmụmaatụ, akụkụ na-arụ ọrụ nke vanadium catalyst bụ V2O5, cocatalyst bụ alkali metal sulfate, na onye na-ebu ya bụ diatomite nụchara anụcha. Nsonaazụ na-egosi na SiO2 nwere mmetụta nkwụsi ike na ihe ndị na-arụ ọrụ, ọ na-abawanye na mmụba nke K2O ma ọ bụ Na2O. Ọrụ nke onye na-eme ihe na-ejikọta ya na mgbasa nke nkwado na ihe owuwu pore. Mgbe emeso diatomite na acid, ihe adịghị ọcha oxide na-ebelata, ọdịnaya SiO2 na-abawanye, akụkụ elu nke kpọmkwem na ụda pore na-abawanye, ya mere mmetụta na-ebu ibu nke diatomite a nụchara anụcha dị mma karịa nke diatomite eke.

A na-etolite diatomite site na foduru nke silicates mgbe ọ nwụsịrị algae nwere otu cell, nke a na-akpọkọta ọnụ diatoms, ma bụrụkwa nke amorphous SiO2. Diatoms nwere ike ibi na mmiri ọhụrụ na nke nnu.

Akụkụ bụ isi nke diatomite eke bụ SiO2. Diatomite dị elu dị ọcha, yana ọdịnaya SiO2 na-adịkarị karịa 70%. Otu diatoms enweghị agba na nghọta, na agba nke diatomite na-adabere na mineral ụrọ na ihe ndị dị ndụ, wdg, na ihe mejupụtara diatoms sitere na isi mmalite ịnweta dị iche iche.

Diatomite bụ ihe nkwụnye ego diatomite fossil nke e hiwere mgbe oge nchịkọta ihe dị ka 10,000 ruo 20,000 afọ gasịrị mgbe osisi nwere otu mkpụrụ ndụ nwụsịrị nke a na-akpọ diatoms. Diatoms so na protozoa mbụ pụtara n'ụwa, na-ebi na mmiri oke osimiri na ọdọ mmiri.
