Agricultural Uses Silica is silicon dioxide, one of the most abundant materials on the earth's crust. Quartz is an example of silica. It is used as a filler in fertilizers, and also, in the manufacture of glass, ceramics, abrasives, rubber and cosmetics. Safety Profile .
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand.Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product.

Silica sand is used extensively as a raw material for producing glass, and with suitable binders, to make molds for metal castings. The Cheyenne sandstone of Barber, Comanche, and Kiowa counties, Kansas, is composed of loosely cemented grains of silica associated with approximately 2 percent other minerals.
Abrasives. There are so many options when it comes to choosing the right blast media for a particular finish. Productivity and cost must be the first consideration when making this decision, although, sometimes a specific finish can only be achieved with a media that may be more expensive than others.

The designation -325 mesh is simply saying the powder passed through a 325 mesh screen. If you needed a powder that was closer to size you would need to specify two mesh sizes. For example: Tantalum Powder, -40+100 Mesh, 3N8 Purity. This powder would have particles that were smaller than 40 mesh (420 micron) but larger than 100 Mesh (149 micron).

Crystalline silica exists in several forms, the most common of which is quartz. If crystalline silica (quartz) is heated to more than 870°C, it can change to a form of crystalline silica known as trydimite, and if crystalline silica (quartz) is heated to more than 1470°C, it can change to a form of crystalline silica known as cristobalite.
