Diatomaceous earth may be heated to high temperatures (called calcined diatomaceous earth) or left unheated (uncalcined); only uncalcined material is used as an insecticide. Aqueous solutions of sodium silicate can be dried and formulated into very light powders that are more effective (require less material); this is called silica aerogel.
