What is silicon dioxide?

Silicon dioxide is the most abundant mineral in the earth’s crust. It is found on all continents in forms ranging from fine powders to huge rock crystals.


Silicon dioxide properties

Silicon dioxide is a crystalline solid at room temperature. The pure silica is white and the density is 2.2g/cm3. It consists of one silicon atom and two oxygen atoms; the atoms are tightly bound together, making it resistant to many irritating chemicals. In nature, silica occurs in the form of sand or quartz crystals, which is relatively hard compared with most minerals. Silica has a strong heat resistance, with a melting point of 1650 (3000 degrees Fahrenheit).


What is silicon dioxide used for?

Silicon dioxide is used in many different ways. One of the most common uses is to make glass, an overheated and pressurized silica. It is also made for toothpaste. Because of its hardness, it helps to remove plaque from teeth. It is also a major ingredient in cement and used as an insecticide. Silica gel is a food additive and desiccant that helps to absorb water.


Is silicon dioxide harmful to humans?

Although silica is largely harmless, it poses health risks when inhaled. In powder form, small particles of minerals remain in the esophagus and lungs. It does not dissolve in the body over time, so it accumulates and stimulates sensitive tissue. One of these conditions, called silicosis, causes shortness of breath, fever and cough, and causes the skin to turn blue. Other diseases include bronchitis, with few cancers.
