Koj yuav paub li cas yog tias koj muaj diatomite?
Diatomaceous ntiaj teb. Diatomaceous lub ntiaj teb los yog diatomite yog ib lub teeb-xim pob zeb sedimentary li ntawm siliceous shells (frustules) ntawm diatoms. Diatomaceous lub ntiaj teb yog pob zeb mos thiab friable. Nws tawm ntawm tes plua plav yog kov thiab muaj lub cev tsis taus zoo li nws muaj qhov muag muag thiab lub teeb yuag sab hauv.
