Product introduction and history
Silica is a mineral in the earth’s crust that is abundantly present on all surfaces of the earth. This substance exists in a variety of crystalline and amorphous forms. The reason for this variation is due to the flexibility of connection among 4SiO tetrahedrals. The stable crystalline form at room temperature and thermodynamically stable is quartz. This mineral is widely available and is one of the main ingredients of many ceramics and glasses.
The name silica is used for all minerals with the general formula 2SiO. The name Silicon is derived from the Latin word (Silicis) which means hard stone, flint or flint.
Silica is the second most abundant element in the earth’s crust with an abundance of 25%.
Silica is a non-metal, hard, colorless to white or dark gray with Si, atomic number 14, atomic weight 28.085, specific gravity 33.2 grams per cubic centimeter, hardness 7 on the Mius scale, white khaki color, no cleavage The boiling point is 2355 degrees Celsius and the melting point is 1410 degrees Celsius.
Silica is the main component of sandstone and siliceous sand, quartz and quartzite, crystal, triply and novacolite, artificial silica and chemical silicon, clay minerals, granite, tuff and diatomite.
Most of the land is covered with sand. Sand is made of only two elements: oxygen and silica, these two elements play a very important role in our life and human life.
Sand is a material that humans have known and used in their lives for thousands of years. Example: in house building, in ceramic making, etc., but in the 19th century, an important change occurred in Alim Shayimi, he introduced sand to the world as the most useful material for human life.
Silica is produced by crushing rock beds that contain this sand and is also found in abundance in nature.
Silica for water purification is one of the operations and processes that have been used for a long time. The first documentation of silica in the water purification industry dates back to 1804, and this coincides with the time when John Gibb designed and installed filtration filters.
Of course, the theory of this process started in 1804, but after about 20 years, it was expanded and refined. The first source of water purification by silica was designed and built in 1829 by James Simpson for the Chelsea Water and Wastewater Treatment Company.
After that, one of the most famous physicists named John Snow discovered the relationship between water quality and water quality, and then he continued the main and important studies for water filtration and purification, and finally, in 1855, the standards related to Water quality and drinking water filtration were tested.
Today, silica is known as one of the most widely used materials in the water and wastewater treatment industry, and it performs the water filtration process in sand filters by forming a silica bed.
Silica purifies water physically and due to its unique properties, it is used in the purification of drinking water, swimming pools and water parks, paper, chemical industries, etc.
