Silica is the name given to a group of minerals composed of silicon and oxygen, the two most abundant elements in the earth’s crust. It is a natural compound, found all around us in nature. Silica can be found in most rocks, clays and sands. It is created when cutting, sawing, drilling, and crushing stone, rock, concrete, brick, block, and mortar. Silica in its finest form is also used as functional filler for paints, plastics, rubber, and silica sand is used in water filtration and agriculture. Silica is used as a filler in the cement, as well as in heat insulation and filling material for polymers and grouts. Silica is found commonly in the crystalline state. Crystalline silica, also referred to as quartz, is a common mineral. It’s found in soil, sand, granite, concrete, rock, and many other materials. In its crystalline form it is used in hydraulic fracturing. Used in the production of glass and used as a sedative. It is also used in the metallurgical industry as the raw material for silicon metal and ferrosilicon production. Silica sand is used in buildings and roads in the form of Portland cement, concrete, and mortar, as well as sandstone. Silica also is used in grinding and polishing glass and stone, in foundry molds, in the manufacture of ceramics, refractory material and as gemstones.
