Diatomite's physical qualities have led to its employment in a variety of commercial applications, the most prevalent of which being liquid filtration and filler applications, such as paints. Diatomite is also used as a pesticide and for insulation (fire bricks).
Diatomaceous earth is made up of fossilized diatoms.
The diatomite has these applications due to its lightweight, porosity, and ability to endure higher temperatures:
For polishing metals, it's used as an abrasive.
Toothpaste and toothpowder manufacturers use it.
Steam pipelines and blast furnaces are insulated.
Filters are used in the brewing, oil refining, sugar, and antibiotic industries.
Corrosive chemicals, notably explosives, are packed in this container.
In dynamites, it's used as an absorbent for liquid nitroglycerine.
Glasses, paintings, and porcelain are all made with it.
