Diatomaceous Earth (DE) is a natural silica source formed from the sedimentation of single cell aquatic organisms called diatoms. DE can form in marine or fresh water environments and exhibit properties that are related to their unique shape and structure. These properties vary according to the diatom species found in each deposit, each with differing chemistries, shape factor and pore structures. Diatomite is the name of processed DE.
Natural grades are dried, milled and classified. The naturally bright ore is dried at about 200° C, sized and packaged. There is no high heat treatment. These products typically contain less than 0.1% crystalline silica. DiaFil grades are highly effective in gloss and sheen control.
