Babban bangaren diatomite a matsayin mai ɗauka shine SiO2. Misali, bangaren aiki na masana'antar vanadium mai kara kuzari shine V2O5, cocatalyst shine alkali karfe sulfate, kuma mai dauke da diatomite mai ladabi. Sakamakon ya nuna cewa SiO2 yana da tasiri mai ƙarfafawa akan abubuwan da ke aiki, kuma yana ƙaruwa tare da karuwar K2O ko Na2O abun ciki.

Diatomite gabaɗaya yana samuwa ne daga ragowar silicates bayan mutuwar algae mai sel guda ɗaya, tare da ake kira diatoms, kuma yana da hydrated amorphous SiO2. Diatoms na iya rayuwa a cikin ruwan gishiri da sabo. Akwai nau'ikan diatoms da yawa, waɗanda gabaɗaya za a iya raba su zuwa "tsakiyar hankali" diatoms da "feather striata" diatoms.
