Specifications of Diatomaceous Earth FCC Food Grade:
Diatomaceous Silica; Diatomite; D.E.
CAS: natural powder and calcined powder [CAS 61790-53-2]
CAS: flux-calcined powder [CAS 68855-54-9]

DESCRIPTION
Diatomaceous Earth occurs as a powder of varying colors consisting of processed siliceous skeletons of diatoms. The natural powder (gray to off white) is air dried and classified by particle size; the calcined powder (pink to buff-colored) is air dried, classified, calcined at a high temperature (815C to 982C), and again classified; the flux-calcined powder (white) is air dried, classified, calcined in the presence of a suitable flux (generally soda ash or other alkaline salt), and again classified and the acid-washed powder is any of the preceding powders having been further purified by washing in acid and rinsing with water. It is insoluble in water, in acids (except hydrofluoric), and in dilute alkalis.
Function: Filter aid in food processing.
