Njirimara microstructure nke diatomite

Ngwakọta kemịkalụ nke ụwa diatomaceous bụ SiO2, mana nhazi ya bụ amorphous, ya bụ, amorphous. A na-akpọkwa SiO2 amorphous opal.

Ngwa nke diatomite

N'ihi microstructure pụrụ iche nke diatomite, ọ nwere ọtụtụ ngwa ngwa n'ọtụtụ mpaghara dịka ihe owuwu ụlọ, kemịkalụ, ọrụ ugbo, nchekwa gburugburu ebe obibi, nri, na teknụzụ dị elu. Na Japan, a na-eji 21% nke ụwa diatomaceous eme ihe na ụlọ ọrụ ihe owuwu, 11% na-eji ihe na-emegharị ihe, na 33% na-ebu na ndị na-ebu ya.
