What is diatomite? Diatomite or tunnel soil, also known as diatomite, diatomide, diatomaceous earth or kieselguhr soil, is a type of soil composed of fossil remains of single-celled algae belonging to the family Basilriophyses. In its skeleton, it contains significant amounts of silica and its sediments are in the form of fine grains. In addition to silica, small amounts of organic matter, clay and in some cases volcanic sediments are also observed in its structure.
Since this soil is composed of cell wall, it can be converted into powder. Its cell wall contains silica and diatomite soil silica content reaches up to 90%.
In most cases, it is a white powder and its particle size is 5 to 1000 micrometers and generally has a size between 50 to 100 micrometers, which are classified into different sizes according to different applications. Its distinctive features include its high absorption power up to 2 times its weight.
The first production of diatomite soil dates back to 1884 using reserves in Maryland. First, after harvesting from the mine, it is raw and calcined and processed, in which diatomite soil with different grades can be produced for different applications. Its first use dates back to 2000 years ago by the Greeks. The Greeks used this soil in the preparation of pottery, ceramics and pottery. It was also used in the early sixth century to build the Sufi church in Constantinople.
Alfred Nobel, the famous chemist, created TNT due to its ability to absorb liquid nitroglycerin, which is widely used today to increase safety in the transportation of these materials as well as in mining.
Comprehensive applications of diatomaceous earth (Tuncel soil):
Diatomite soil has the highest consumption as a filter aid and filter of suspended particles. Its main use in material filtration can be used in: antibiotics, juice filters, urban waters, drug filters, aircraft fuel, pool water filters and sugar factories.
In the paint industry, it is also used as a filler in the manufacture of paints, paper and abrasives, and by using the filler property of this soil to control the transparency and brightness of the paint. Other uses can be used in the insulation industry, so that the global consumption of diatomite soil in this industry is equivalent to 200 to 250 thousand tons per year.
