[Diatomite]
 
   Diatomite comprises irregularly shaped diatom frustules with a chemical composition similar to opal or hydrous silica.The diverse structure and ornamentation of the frustules range from radial symmetry, resembling wheels, discs, & golf balls to bilateral symmetry looking like boats, feathers, ladders, needles, etc. While the frustules range in diameter from 5 to 1,000 ?m, the majority is in the 50 to 100-?m ranges. In the typical lace-like patterns, the combined area of the holes ranges from 10 to 30% of the total area. The range of grades may be extended still further through blending and the addition of cellulose fiber (particularly for precoating).
