Silica Sand – Shree Ram Group of Industries
Introduction Silica is the name given to a group of minerals composed of silicon and oxygen, the two most abundant elements in the earths crust. Silica is found commonly in the crystalline state and rarely in an amorphous state. It is composed of one atom of silicon and two atoms of oxygen resulting in the stone formula SiO2 Sand consists of small grains or particles of mineral and rock ...
Silica - an overview | ScienceDirect Topics
Fused silica is produced by fusion of very high-quality silica sand feedstock in electric arc and resistance furnaces. This converted silica can be used as a filler or electronic encapsulant. High-purity ground silica is a product from silica sand or soft friable rocks as an amorphous silica. It is mainly used in specialty, coating, plastics, rubber, electronics abrasives, and optics ...

Mesoporous silica - Wikipedia
Mesoporous silica is a mesoporous form of silica and a recent development in nanotechnology.The most common types of mesoporous nanoparticles are MCM-41 and SBA-15. Research continues on the particles, which have applications in catalysis, drug delivery and imaging.. A compound producing mesoporous silica was patented around 1970.
Sand casting - Wikipedia
Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.Over 60% of all metal castings are produced via sand casting process.
