Isi ya Diatomaceous ni ubwoko bw'urutare rwa siliceous sedimentary rukomoka ku binyabuzima, rugizwe ahanini n'ibisigazwa bya diatom bya kera. Imiterere yarwo ahanini ni SiO2, irimo ingano nto ya Al₂O₃, Fe₂O₃, CaO, MgO, K₂O, Na₂O, P₂O₅n'ibintu bikomoka ku bimera. Imikoreshereze y'ingenzi ya diatomite ni ibikoresho bifasha mu kuyungurura, ibirungo, ibirungo bifasha mu kuyungurura, ibikoresho bifasha mu gukurura ibintu, ibikoresho by'ubwubatsi bitangiza ibidukikije n'ibindi.
