Calcined Diatomaceous Earth
Calcined diatomaceous earth has been treated at a temperature above 1500F to agglomerate the exoskeletons of the diatoms in order to create a range of permeabilities for better filtering agents. While it is used primarily as a fine filter aid, it has many other uses.
The characteristic color of calcined diatomaceous earth comes from the oxidation of iron during calcination; it is sometimes referred to as “Pinks” for this reason. Our natural grades are off-white.
We produce our calcined DE at two locations: Basalt, Nevada and Burney, California. We can ship to your worldwide location by utilizing our close US West Coast shipping ports.
